anyway, i have a question for the general:
should i use a 12V 20A switching power supply over a standard 12v 10A wall adapter for my printer?

the printer i got has some reports from other owners of the stock power supply failing (it's one of those big plastic laptop style power supplies)
the switching PSU i have is one of those units that come in a silver aluminum case with a fan and has screw terminals (iirc, some printers come with these)

would the amperage be too much?
i have noticed huge dips in bed and hotend temps right at print start, though (seems like power issues to me)
only other thing than amps is the polarity on the printer power jack that i'd have to figure out, which should be easy

When I found it, I turned the extruder up to 210 and pulled it off. Smoke emitted and smelled like burnt plastic. Maybe the hot plastic melted the wiring insulation? This is what it's like now and I'm afraid to reheat it (I still have a headache). Any idea of what to do? I have a dual extruder (e3d chimera) so I could just install that. Problem is this is one of my first dozen or so prints. I never really got got good prints with PLA with the stock hot end (the ABS fan shrouds came out fine but those were just two). Can I salvage this one? How? Or should I just install the chimera?

also, might just rig up a spare computer ATX psu instead


also wanted to ask:
abs juice (liquidy) vs. abs slurry: which is better?
i used some low ratio abs juice and prints have stuck well to the heated bed with very little warping on a cold spot
would it be worth making a thicker abs slurry? it seems like it would take just a bit more effort to apply evenly, though
>>
>>1077103
Me and a couple other people made the OP copypasta during the first general. It was whipped up in a day as sort of a placeholder, but very little work has went into it since then.

The 2015 one that was up from the same site was just as bad

I've switched to purple gluestick at this point. slurry is too high maintenance.

The purple is very important.

I get good results with PVA based wood glue.
I mix it with 5 parts water and whipe it on the bed at 60°C.

I have 2 printers both running on 30A Supernight power supplies.

Knock on wood, but I havent had an issue with either of them (other than the fan being noisy, but my one printer is covered in noisy ass fans).

I would buy the 30a over the 20a just to have the headway if you need it, you wont be running your PSU as hard and they only cost a few dollars more (for the cheap clones)

>>1077339
The i3 design is good and very popular, many people have all different variants of it.

The "Original Prusa" made by Josef himself come with high end parts which is why it costs more than cheaper ones.

Its going to be a nice printer. I know of at least 1 guy who has bought the original and posted about it ITT.

There are people with dirt cheap bottom of the barrel kits who do just fine with the design, having the money to buy a premium kit is a really nice thing.

I finished them. The flash makes it look like there are a lot more voids and imperfections than you can actually see IRL.
There were just real quick .3 layer prints to see if they fit. They pass the eye test well enough im probably going to just leave them.

>>
>>1077360
Its an open source design. He released the design for anyone and everyone to do as they please with it. Whether it be to modify it or sell it or whatever.

So in essence there cant really be a "knock off" of the printer.
He only recently started selling the printers themselves, while people have been selling his design for like 4-5 years now.

By "knock offs" it talks about on the sales page is referring to the cheap clone Arduino based boards that control the printers. A lot of them are complete shit, but they work and are dirt cheap.

You can buy an i3 printer kit that will lay plastic for 200$.
It just has very low quality parts that you will eventually want to replace or they will fail.

Thats were buying the premium kit comes in. It has a very high end electronics board, and a very high end hotend (two things you would want to replace in the cheap kits). And of course it has a better frame which is a lot harder to replace if you get a cheaper kit.

It also comes with acme screws and of course its got the auto leveling calibration deal.

But a cheap kit will get by perfectly fine. There is a pretty steep learning curve regardless.

Its a great printer, but cheap kits make great printers in the right hands too.
>>
>>1077363
Thanks. It wasnt really the first print. I printed a few 1-2 layer pieces to check for fit. It was the first full chamfered piece with the screw hole in it.

The whole scanning a traced paper into a SVG and then cleaning it up in photoshop got it very close first shot. Im shocked at how well it worked

>>1077368
I think I'm going to go with the expensive one

>>1077372
Keep us updated on it.
I have seen auto leveling sensor upgrades before, but ive never seen that full XY calibration thing.
It looks like a pretty interesting setup

Yeah, the tracing (or just placing what youre trying to fit into on a scanner) is a great way for making parts, especially when you need to match irregular shapers like that

It is not that good but I haven't seen a better one yet. The copypasta needs some rework in the hotend and filament sections and I think that we should move it a bit away from advertising. Also there should be some links for SLA, SLS and other techniques.
>>
>>1077405
It's kinda hard not to advertise in it, it's such a niche market with so little brands.
It's not like the thread was paid by E3D, but there aren't any other good hotends out there.
>>
>>1077407
Yes the E3D is the best alternative and I think that j-head doesn't even exist anymore. For filaments I thought that there should be categories: "most commonly used","a bit harder to use" and "special filaments" and then just a recommendation not to buy the cheapest chinkshit one can find.

I was worried that he'd just download a few things off Thingiverse and then it would collect dust in the corner of a room, the guy's 62, a retired electrical engineer and he took to CAD like a duck to water. His first design was a skeletal tablet stand, designed to be printed without supports and it came out perfectly. One of his daughters is a civil engineer so, naturally, anything he designs is getting pretty brutally scrutinised.

>>1077741
>Any suggetions / opinions regarding self build SLA/DLP printers?
check out the buildyourownsla forum
>Any downsides to consider compared to the standard DPM printers?
Resin handling is a mess.
There is a different set of problems like adhesion to the vat floor for bottom-up designs and inconsistent layer height for top-down. Then there is light bleed to worry about and in my case random uncured holes likely related to bubbles. I often end up using my FDM machine instead.

>>
>>1077741
you definitely want to use http://www.nanodlp.com/ to control it
the concept of your printer acting as a server and accessing it from any browser without having to install additional software is just awesome
>>
so i finished my first big print recently and i had to make extensive use of supports
the piece is very detailed (like relief sculpted into stone, lots of overhangs)


is there anything to removing supports or do i just get cracking?
also, are there any settings i can change to make the supports weaker/easier to remove?
i think on my next prints i might reduce support line width, i guess


https://www.youtube.com/watch?v=bnpEfRWqDKU
>>
>>1077383
And once you got an image, openscad can extrude that shape for you (see surface command) ;-)
>>
>>1078563
I just crack em, and then use an exacto blade to cut the remaining stuff.

Weakening and reducing supports is all done within settings of your slicer (assuming you used your slicer to automatically add supports)
Some slicers work better than others.

I've just found the perfect way to release prints without any effort on my part. I'm using a borosilicate glass bed so it might be risky to try this with a soda glass bed.

Essentially, you print with the bed heated to 60C then transfer immediately to a fan, I use this Honeywell fan because the front is flat and it can be pointed vertically upwards, two of the corners rest on the inside of the lip and a small printed stand holds it at an angle to allow decent airflow. Within 5 minutes the parts usually come off of their own accord or, at worst, pop off with a gentle tap. I've tried letting the bed cool slowly with the same part but it seems like shock cooling is the answer.

I'm thinking of putting together a thermoelectrically cooled pad for the build plate to sit on after printing to cause even faster cooling.

Bridging each hair to a sacrificial wall. Then you cut them and shape them with heat gun. It is a bit tricky to shape them. They sag due to gravity when they are heated, which can cause problems, but you can also use it in your advantage if you orient part in the way that gravity helps you shape the hair as you want. Strands also like to stick to each other and when they do is hard to separate them without messing everything up. And they also like to curl a bit, but this could be because it is ABS.
That is why hair doesn't have a perfect shape, but is good enough.

If it droops, than you need more fan. But a small droop shouldn't be a problem, as long as all bridges droop the same imo. The problem would be If bridges don't get across. Generally my bridges were fine, but I still got some loose strands, incomplete bridges, drooloops,... I just removed them before shaping it with heat gun

Repair both files and retry. If its not working reduce the mesh in lion and retry. If you ran out of RAM during the process swap is so slow that it can take ages with large files. I've worked with very large mesh files and the longest calculation times has been just couple of hours. That boolean shouldn't take more than few minutes. You can also try that in blender it works sometimes better than meshmixer with booleans (It is still shitty though)

A little update: I tried 123d design. It says that meshes are not closed. I go back to Meshmixer to repair both files. One file is not able to repair no matter how much I try. That is the file I created in Solidworks, so I go back to Solidworks to modify part, to avoid this kind of errors.
Back to Meshmixer. Both files are closed. I try boolean union. Again it's stuck at the same point as before. I give up and start reducing mesh. I reduced mesh for 90% but it still look decent. ok. Boolean union. It looks like it is doing something. After a while it finishes, but there is a lot of holes in the object. I try to tweak some parameters, no improvement and hours are going by. I give up and click Accept, maybe I can repair it somehow later. Get pic related. Fuck. I try 123d design. After a while there is no spinning circle when I hover mouse over the window. Is it done? Click on the window and it disappears. Try again, same result. Fuck.
Not to worry. Next one is Openscad. I have no idea what I am doing. Get some error (ERROR: CGAL error in CGALUtils::applyBinaryOperator union: CGAL ERROR: assertion violation! ...)
But somehow I find out that you can also import STL in Solidworks! What? How have I never heard about this before? So after almost 2 hours it manages to combine those two files together.

tl;dr: It took me 3 whole days to combine 2 files together.

My 10th generation tronxy prusa i3 shits itself when I try to heat the bed, I can't really pinpoint the source of the problem.


Whenever I try to preheat the bed, or send a job to the printer, it heats up normally, maybe 5°C or 10°C, then, the bed temperature reading shoots from a normal temperature, like 40°C, to 750°C or so in <1 sec, it stays there for less than a second and comes back to 40°C, then the printer throws the following error:

>Err: MAXTEMP BED
From there I have to unplug my printer and start the heating process again, otherwise, it just stops heating the extruder and bed.

Strangely enough, this issue happens more commonly when the bed is at room temperature, if it's >50°C, sometimes it has no problem reaching 65°C without throwing an error.


At the moment this issue is driving me crazy, since I would have to spend ~30 minutes alone heating up the bed in 2, or 5 °C increments

Should I simply replace the thermistor/sensor on the bed and hope for the best? I inspected the cables coming from the main board and they seem OK, I wiggled them right where the bed makes contact with the sensor and it didn't help.

Sorry if I made this post longer than it should be
>>
>>1082728
It sounds like a fucky thermistor to me, I would replace it.

I would NOT turn off the maxtemp bed failsafe.
You dont want a runaway heated bed due to a failed thermistor.

Your failsafe software is working correctly.
>>
>>1082743
Thanks, I did think of disabling the maxtemp bed failsafe just for a test, fortunately I couldn't find that option in the menu of the printer, I guess there's no point in risking the heated bed for a part that can be replaced very cheaply.
>>
>>1082753
>fortunately I couldn't find that option in the menu of the printer,

Its done at the firmware level of your Ramps/Arduino.

Im not sure how hot a heated bed can theoretically get, but I know that runaway heater cartridges get hot enough to melt aluminum. I cant seem to find the pic, but someone had an all metal hotend with a runaway heater cartridge and it melted the whole heater block.
A dislodged heater cartridge or hotend that has melted down is how 3d printers catch fire and burn houses down.

Bed maybe not so, but could still be dangerous

any recommendations on cheap smoothie compatible boards?

you maybe misinterpreted my post I'm not looking for 32bit microstepping but a 32bit processor
delta printers greatly profit from the increased processing power since the mathematics to position them accurately are more complex than in cartesian systems
8bit boards just can't keep up at high speeds and you'll get worse resolution/accuracy especially at the edges of your buildspace

>Couldnt you just buy a cheap smoothieboard clone?
sure but the cheapest ones are $50 vs $25 for a devboard (already got ramps and drivers)

I'm building a 3d printer from scratch.
What gauge wire would be best to run to the hotend, and the bed? I need to go buy a few spools, all my wire is 22 gauge and up. 18 or 16 gauge ok?

its a 12"x12" pcb bed on a 12v powersupply. People are trying to sell me on speakerwire, but seems retarded, being around heat an all.
I could be totally wrong, idk I'm not much of an electrician.

Right now its a generic chinashit extruder i pulled form a previous printer. Works well but nothing to write home about.

Have a spare E3dLite6 and plan on getting a titan and bltouch one day. Volcano worth it too? Its a big printer, so plan on using it for engineering prototypes. Sick of ordering parts from custom fab sites.

I have that exact same saw, and that exact same problem.
>>
>>1083235
What wires do you need for a hotend?
The heater cartridge should have its own wires.

As for what gauge, I personally have 14 AWG from bed -> ramps, and from PSU -> ramps.

I was one of the few who had their Ramps terminals burn up because the wire gauge was too small.
>>
>>1083239
heater cart just needs longer wires to reach the board.

I'll go for 14 AWG then, better too thick than too thin.
>>
>>1083235
don't run your hotbed on low voltage DC,
the high currents you need to get any reasonable amount of power are a huge fire hazard,
see >>1083239
>Ramps terminals burn up
run your hotbed on mains power controlled by a SSR, this is not only safer but also more energy efficient
since you don't have the losses from a power supply

also use 24V for your steppers and heater cartridge,
you'll get quicker movements and thinner more flexible wires to your hotend,
also less losses in your wiring

Until today, I had volume issues with my prusa clone. It would shake the house down, and even over the TV I'd hear the constant drone of it vibrating away.

People mentioned placing a foam mat under the printer to keep it quiet. I didnt think it would make much difference, but I picked up some kids foam play mats, placed one underneath, and the difference is insane.

This machine is now an order of magnitude quieter than it was before.

Mucho recommendo

My NEMA 17 for the extruder is making a very weird noise, like "wi-wi-wi-wi-wi-wi-wi-wi..." constantly, and when it stops extruding makes another continous noise...but I don't see anything weird with the overall performace of that NEMA.

Also, I put my 2 Z axis NEMA on 0.40 miliamps and they only make more noise, is it adviceable to lower the amps or is just fine as it is?
>>
>>1083328
Whining probably means you are running them really hard.

What kind of stepper drivers are you using?

A currents differs on different stepsticks
A DRV8825 is current limit = Vref x 2

So your mulitmeter reads .40 you are running at .8a

An A4988s current limit is Vref x 2.5
So .40 would be a whole 1a.

You need to look at your steppers amp ratings and decide how strongly you are going to drive them.
The stronger you drive them, the more powerful they will be but the hotter they will run.

You put in too much power it will overheat and miss steps.
With that said you dont give it enough power it will also miss steps.
Its a balance of heat and power.

I think I have my steppers running at ~60% of their max rating.
With that said they are decent 84oz, 2a rated steppers. I dont need to drive them hard

I was thinking about getting an expansion kit for my prusa here.

https://www.moebyus.com/partes-filamento/mecanica/kit-ampliacion-de-cama-metacrilato-detail

Ignoring the indigenouspeak this is what includes(for 90 euros)

>200x300 heatbed MK2 with thermistor included and wiring.
>10mm methacrylate support for heatbed
>2 O8 smooth rods of 435mm
>2 O10 crewed rods of 470mm
>4 LM8UU
>1 solid state relay.
>1 meter of MK2 belt
>1 meter of 2 conducting cables.

Or I could try to transition from a prusa i3 to a SIRIUS with what I already have and just buying the structure, new rods, new heatbed and heatbed support. But idk if I should get new printed parts for a complete transition, and although I haven't made the exact calculations the estructure is around 85 euros and the heatbed 65 so I can count that it would be 200-250 euros if the things listed are the only things required.

Which one would you recomend?

I'm thinking of building a Prusa i3 Rework from scratch buying my own parts. How accurate is this wiki?
http://reprap.org/wiki/Prusa_i3_Rework_Bill_of_materials
I've got limited knowledge but it all seems pretty cheap except the hotend.
I was thinking of laser cutting some 6mm ply as it's probably available at my uni and free to use, this requires two extra stands I've seen on some videos I think, pic related.
Any advice?
>>
>>1083995
Plywood frame sounds a bit weak but then again the stresses aren't that massive; I've built mine from 2020 alu profiles. The downside is that mine required all custom parts that I had to cut on a CNC, couldn't just order a set of prusa plastic parts, but that was largely because I also used openrail V slot style rails instead of 8mm steel rods, and 12mm trapezoid threaded rods plus 12mm steel rods for Z axis (only real reason behind that was that I had them laying around). V slot rails are a lot quieter than rods, but then they have their own set of problems.
I bought a cheap chink e3d knockoff hotend for under $10 and it's working fine. Supposedly it's a bit of a gamble as some of them are shit and end up jamming, but mine has been working fine. I planned my printer for 24V instead of 12V straight off and it proved to be a good decision because I can push the heated bed a lot more, though the chinkshit RAMPS' bed mosfet ended up failing when I was running the bed at around 180W, I just replaced it with a better one for now. Eventually might just switch to a relay.
>>
>>1084027
What's the MOSFET?
There's an extra support with the plywood that's supposedly to stengthen it, I have access to some CNCs but it'll be difficult to produce the frame shape for the i3 a it's all sharp corners. Do you also mean you produced the printed parts on a CNC? There are so many I'd probably rather spend the ~£25 to get them off ebay. This would be the first printer I've made so I'm gonna keep it vanilla.

Anyone else have problems with their heated bed as such?:

It has a hell of a time getting to the set temp when it's set above 70. It can get up to one degree under the target temp, and then it drops 5 degrees, goes back up 5, drops 6, goes up 4 etc etc... but when it finally hits the target temp (40 minutes later) it has no problem maintaining it.

I originally had it at 90, and then set it to 80 and the exact same thing happens. I've tried altering the PID values using this: http://reprap.org/wiki/PID_Tuning as a reference but I feel like everything I do just makes it worse. Any advice would be appreciated!
>>
>>1084028
MOSFETs are transistors on the RAMPS board that switch the power to the bed and the extruder heater. And yeah, I produced alternatives to the printer parts on a CNC, from HDPE, but I replaced most of them when I got the printer to work, they were only meant to be temporary.
>>1084064
I sourced the parts one by one and built my own, the total costs were just over 200 euros, no customs to pay. I ordered everything from china, the only issue I ran into was that some of the steppers had slightly misaligned shafts. This isn't something that would ruin regular prints, but it might be better to buy the steppers locally if you want to make sure that precision is as good as it can be.
>>
>>1084211
Have you also sourced your 2020 from China?

Nah, that and the filament were cheaper to buy in Europe, motedis.com. They have expensive shipping, some 15 euros, but the profiles themselves are the cheapest I could find by a long shot. They also have very cheap filament, but in the long run it's not worth ordering from them because of the shipping, I just got one roll with the extrusion order.
>>
>>1084137
Consider using bang-bang temperature control for the bed rather than PID; I find it works better for me. Failing that, you can try modifying the PID parameters manually as per:

I don't know how is that possible. It is like I had woken up in different timeline. I had googled how to import stl in solidworks, although it was a while ago. Maybe that was not the option at the time and is only available in newer versions.

The shaft of the stepper is at an angle, maybe it's bent somewhere, I don't know, but the point is that it's not an exact 90 degree to the front surface of the motor, but maybe some 87. This makes your leadscrew move around as it rotates, messing with the height.

Is there any reason not to get this 3D printer?
>>
>>1086301
I have one. It's a fun project. I feel like I've replaced half of it. Definitely the best printer at it's price range, but to get it printing really well, there are a few mods people recommend.

>>1086319
>Is there any reason not to get this 3D printer?
You can spend more money to get a better printer. Better printer is less hassle. But of course you'd have to spend more money.

There's so many recommended changes like Z-braces, glass plate, metal extruder, compared to something like the Prusa i3 mk2 that is 100% out of the box.

Still the best for that price though.
>>
>>1086319
>>1086301
There is nothing wrong with the printer

Just be ready for a hobby that has a very very steep learning curve, thats expensive, and the results arent all that great.

If you dont go balls deep, itll end up sitting in a closet because its too much of a pain in the ass to master.
>>
>>1086324
Z braces are unnecessary and in many cases introduce banding in an I3 design. They can help out the rigidity of an acrylic printer, but thats not needed with the boxed steel wanhao.

Maybe the official Prusa which doesnt have a metal frame benefits from it too. Who knows.

The official Prusa kit is ok, but its pretty expensive for what you get.

You dont get metal frame, you dont get hardened rods, you dont get high quality bearings, its a proprietary heat bed, you dont get a full graphic LCD, you get the same old shit PSU, you get meh tier steppers.

If you would price out a top tier I3 yourself in the 700$ range, you could have all that and more.

Instead you are paying out the ass for a full metal E3D, for "real" electronics", and for Prusas leveling and calibration files. Ignore the corners cut on the rest of the printer becuase they will work ok too. You could get a printer that works "ok" for a whole lot less money.

I dont fault people wanting to support him, but its not a bang for buck printer at all.

An E3D lite is easier to use and doesnt require active cooling like a full metal E3DV6.
The high end electronics that work no better than cheap clones have no bearing on end print quality.
Getting a reprap printer kit under the guise of "its plug and play" is a fucking joke and will make it much harder in the long run when they dont learn fundamentals of their printer using autoleveling.

And the auto leveling itself is terrible on an I3. Its a bottleneck to your speed because it causes you to overwork your Z axis and causes more vibration. The I3 wasnt designed to move the Z axis during XY movements originally.

Its not a significantly higher printer and it wont have better prints, even though it costs more than 50% more money.
>>
>>1086332
Z braces are helpful because the vertical frame is only held to the base by a few screws, which aren't going to stop the thing from moving. I would not want to pick up the printer from the top without the z brace mod.

An e3d lite doesn't require as much active cooling, but I wouldn't want to use it without it. Most hotend designs don't passively get rid of heat enough to prevent heat creep.

I will agree the electronics don't seem that good compared to a standard RAMPS. And why the fuck does it not have the full graphic display which is only slightly more expensive.

But overall it's still a kit and some people don't want to deal with selfsourcing everything, and the only comparable kit I think would be the RepRap Wilson II. Which I might like better actually with it's extrusion frame and the guy's custom PICA board.

What programrs do you use for your 3d printer and why?(and of course, include the 3d printer you use asuming you have just 1)

I've been trying to make one of those cheap-ish filament extruders, something along the lines of http://www.instructables.com/id/Build-your-own-3d-printing-filament-factory-Filame/

Since ABS is relatively difficult to print and PLA is very difficult to source where I live, I've decided to try going for either PET or PETG. I managed to procure some 30kg of PET regranulate and about 20kg of PETG regrind. Things that I've learned:
>it's very hard to source plastic if you want less than a metric ton
>but you can lie about only wanting a sample, nobody cares about sub-50kg amounts
>PET is completely unsuitable for this kind of extruder, you need to extrude it vertically and directly into water
>these car wiper motors are just-barely strong enough for a 16mm screw to run more or less consistently when extruding pellets
>they're definitely not strong enough to work with regrind flakes, which frequently get stuck and need to be cut through
In light of this, I changed plans and will try to get a single-phase AC motor around 300-500W that is geared down to ~70RPM, as per the precious plastics extruder. I'll change the support, swap to a larger auger bit, depending on what size of steel tube I can find that matches precisely, so as to have an easier time with PETG flakes (flakes are again easier to source, or rather, you can only source flakes here). I'll probably design the whole line around vertical extrusion, but the tube and the motor will be horizontal, I'll just add a 90 degree turn near the extruder and another heating element after the turn.

Oddly enough, the only project I managed to find where people actually tried to extrude PET filament is https://www.wevolver.com/matthew.rogge/thunderhead-filament-extruder/main/description/
>>
>>1086464
cool stuff. post pics.
Did you consider making 3D printer with direct extrusion from granulate instead of making a filament? Wouldn't that be easier and cheaper?
>>
>>1086490
It looks almost the exact same as the one in instructables, just with a bigger mess around it. I welded the tube instead of using all kinds of screw-on crap, but that was about the only major change. I'll post pictures once I get around to sourcing all the shit for the second version, but it's gonna be a while.

I saw some people doing that direct extrusion but I don't think it's a great idea. Compared to filament, feeding granulate is a lot more inconsistent, you also need a lot of power to turn the auger, which means the whole assembly is going to be heavy and yet it's still not going to be powerful enough to work as reliably as filament extrusion. I'd prefer to have the printers remain their own thing and doing what they were meant to do, instead of adding yet another layer of complexity and source of problems.
>>
>>1086494
I was thinking that if you can extrude a filament with more or less consistent diameter you should also be able to extrude consistent lines for 3d printing. Of course the table would move in x, y and z direction, so the extruder can be as big/heavy as it needs to be. A potential problem could be start/stop and retraction, but something like spiral vase should work imo.

Something to think about, if filament extrusion doesn't work out.
>>
>>1086499
Thing is that for extrusion you need a ton of shit to make it consistent, pullers, coolers, sensors, industrial machines have multizone temperature control and special screws even, plus as I said motor power is a big issue. On these small machines, people are super happy if they get +-.15 accuracy, the typical filament is .05 (though rated .1). Overflow would inevitably be bigger since you need larger heat chambers. I don't see it as worth all the bother, unless you are doing 3D printing as a service and have printers running all the time. If I manage to make good enough filament, I'll probably offer it for sale to offset the costs of the machine - there's no such opportunity if you build a printer that uses pellets. You might be able to sell the printer I guess, but I wouldn't count on that.

I keep blowing up my Arduino Mega's voltage regulator. The symptoms are that the LCD screen is super bright and the text is washed out and you can barely read it, but it'll work fine if you power it through the USB 5V and rip out the voltage regulator. On the robotdyn megas, the voltage regulator is completely destroyed, and will only take 5V power. I've just ordered some new voltage regulators on Aliexpress to try fix them up and so I don't have to spend more money on MEGAs.

So it's not really /3dpg/ but it kind of is. I'm planning out pic related for a future CNC build. I got some amazing linear bearings out of some biotech gear and it prompted me to get my ass into gear and make a machine.

Mechanically it's good to go, I can easily source what hardware I don't have and electronically I have a good idea of how I'm going to control motors and get feedback from the device. Now comes the time to choose a uC, but that hinges on the part I have been putting off, stepper selection, which I know dick all about. All I really know of steppers is the finer the step angle the better, and as big as you can fit. But I worry about accuracy, pulley gearing ratios etc, and how it all fits together, especially when it comes time to program the controller.

Is there more to stepper selection? And do libraries for stepper control allow you to set your "drive ratios", so, for example, it knows 100 steps in a given direction on servo A always equals 5mm, but on servo B only 45 steps gives 5mm? I guess the whole calibrating-controller-to-pulley-and-gear-ratio-fuckery process escapes me.

How do you guys do it when your scratchbuilding machines?

While belts are fine for 3D printers you should realy reconsider using them if you want to machine stuff.

Hey /3dpg/

Looking for a new printer for my firm.
>structural engineering
>used to print small models / parts of connections to fit together.

budget is limited - up to an absolute maximum of £1350 (budget isn't set by me)

Anyway, a few years ago I built a prusa i3 hephestos - was ok, but print quality wasn't great and it took a lot of tweaking.

have things improved with the self builds?

If not, anyone have any decent workhorse printers for a price within the £1350 budget?

Thanks in advance.

Yeah
I know that for a standard reprap using Marlin firmware that you set your "steps" within the firmware. And you can temporarily change them using the LCD.

You routinely have to change them if you mess around with extruder changes, with different gearing or gears.

There is a calculator in here that gives you "steps per mm" which any controller should be able to use.

http://prusaprinters.org/calculator/
>>
>>1087019
>have things improved with the self builds?

Not really
I bought my first kit printer about 3 years ago, and nothing at all has really changed except stuff has gotten cheaper.

Scratch and kit built printers are as good as its builder and operator, and its still far from plug and play.

For small parts and connectors, youll probably be better off with an resin based SLA printer instead of an FDM printer.

I would search and see what kind of SLA printers you can find in your price range.
>>
>>1086824
>http://reprap.org/wiki/RepRap_Samuel

Looks interesting...the frame thing was to gain rigidity on the X-Z axis
>>
>>1087056
Not necessarily small parts that need to fix together. (Although that would be handy)

I'd be printing models of fully assembled steel connections etc.

We'd also use it to show off structural skeletons of proposed structures that we design basically as a rapid prototyping for buildings.

I've only ever used FDM printers, am I to take it that SLA is better for fiddly stuff, but is lacking in the stuff that FDM is good at?

Are the strength properties any good?

I see your point and am aware of the limits of belts, but the primary use of this machine will be cutting ply and medium duty timber sheet (up to maybe 12mm) and plastics. I have a larger format leadscrew driven machine on the books for metal and full milling, but they will both serve different purposes. For what I'm wanting of it and the nature of the machine (built from 80 odd percent reclaimed scrap parts) this level of accuracy will be more than adequate.

>>1087051
I suspected (hoped) you could, but good to know, and that link is sick as aids. Thanks anon. I'm likely going to be going Atmel for my uC, I'ma bout to dig through some OP links, but any protips on versatile reprap controllers that can be modified to purpose?

So I take it I'm on the money with steppers then. Short of size, power and thermal constraints just use whatever can move the load with a fine a step as possible?

Pic related for those interested, the shell all this shit will be going in. Used to be a fabric printer.
>>
>>1087347
Ramps 1.4 (which runs on top of an arduino 2560) is as versatile as anything if you are looking for reprap controllers.

You install DRV8825 stepper drivers onto the ramps, and you can run big steppers up to 2.2A

Here is a CNC built with 3d printer parts, using a Ramps. So you may be able to use some of the programs or ideas or whatever.

So I recently decided to get my old PrintrBot up and running again. Everything still works, but very shittily; I don't think it was THIS bad when I stopped using it.

Why are my prints turning out so shitty? The model that I have (original PrintrBot LC) uses 3mm filament, and that's what my archaic version of Slic3r is calibrated to - despite this, it looks like it's overextruding, even on a multiplier of 0.9 extrusion. The edges are very wavy, but I've tightened all the bolts (as much as I can with a plywood frame). The bottom layer(s) look like garbage, while the top ones are barely acceptable.

It looks like the printrboard is not a standard reprap electronics board, and uses a modified version of the reprap software.

If you have had print quality issues the whole time, it may be an issue with old outdated firmware

It's faster (on this printer), with my settings) this way. Keep in mind this is an at least 3-5 year old printer; my X and Y axes move faster (and more precisely, hopefully) than my Z axis does so the print gets done faster.

I honestly don't think that any kind of nozzle would poison you given that you print hundreds of meters of molten plastic through it - that much use should clean it even if there was anything on the surface.
>>
>>1088891
You need a stainless steel nozzle, brass has lead in it.
There are a few plastics that can be OK, but the inherent nature of 3d printing leaves printed objects porous enough that they become unsafe over time.

Kind of like plastic cutting boards get very unsafe over time, printed shit gets unsafe much quicker

>brass has lead in it
I don't think that the minute amount of lead that leeches, if any, makes any difference if the printed project is "food safe".

The rest I agree with, though.
>>
>>1089113
sand it flat, preferably coat in safe coating and definitely don't worry about the lead considering what most tap water goes through. Just getting a smooth finish on natural PLA would be enough though for most.

Has anyone else built the ikea LACK enclosure? Sort of works in 2 ways for me by giving a good place to store my printer and also enable ABS printing.

For someone who doesn't have access to a working 3D printer, what is a good extruder(Can be fine with just a cold end as I have a E3D Lite) to start with? The Greg Wade setup I have just doesn't work well, and I am not sure why. I was thinking of grabbing something off of Ebay (Pic related) as I just want to to start pushing some plastic. While I prefer not to use a bowden because I don't want to drill yet another set of holes on to the printer,

You need to give us more information

How do you plan on mounting that extruder you listed if you cant print a mount for it?

Also what symptoms are you having with the gregs wade, because they are a pretty good setup?

Also im not sure why you would need to drill holes in your printer for bowden. You dont have to mount your extuder on the fram
>>
>>1089751
I have pic related mounted to a standard Prusa i3 carriage. I had a friend print it out for me, though I can't reliably bug him for more parts. It's also one reason that bowden may not be a good idea as it can't hold a hot end super firmly without an extruder on top of it.

With the Greg Wade I am having issues with underextrusion, namely after a while it just stops putting stuff out, and past the first layer it is really choppy. The filament isn't grinding based on my inspections. I have tried changing things IE repositioning the hobbed bolt, changing tension, but I am not having much luck. The E3D is set up right I believe as the nozzle is in the right spot and the fan is always running. I am wondering if it is due to the filament that is going in to the extruder coming in from an incorrect angle.

I will look at finding different ways at mounting a bowden. I didn't realize that there were other ways.

I appreciate your reply a ton.
>>
>>1089755
I currently have my bowden extruder (its a printed Airtripper) on an old computer monitor stand.
I cut a piece of plywood out, mounted it to the stand like pic related and then the extruder onto the wood. Works beautifully.
Ive had it mounted on other stuff, hotglued to the bottom of a cup, mounted on the wall, zip tied to a small milk crate.

I too didnt want to drill holes in my I3 frame. Just putting it out there that its pretty trivial to have it mounted elsewhere. It doesnt twist or turn or move so it doesnt really have to be locked down too hard.

I have no experience with the ebay extruders, but I wouldnt put bowden out of the running yet. You could probably make a groove mount like plate to mount your hotend on your existing mount. mount your existing stepper to a 10$ chinese extruder like the red and black ones they sell.

It honestly doesnt seem that painful or expensive to do if you are over the gregs wade.

Maybe others will chime in with ideas on why your gregs wade is failing to work properly.

Mine failed because my large gear wasnt round so I had extreme backlash on 2/4 of the gear, caused underextrusion
>>
>>1089765
Thanks for the advice anon. I just replaced the stand for my computer earlier this month, so doing the same as you will be easy. I will try using a spare groovemount I have and seeing if it fits.

The framework is probably pretty weak on this. Either buy the folgertech kit, or put one together yourself with 2020 alu frame - if you have some basic knowledge about electronics, it's not hard at all to build an i3 clone.
Also, even if they send that printer from Germany, it will not have tax included in the price, you'll be paying another 50 euros for that.

is that for VAT taxes or what?
if it's VAT then i'm fucked because in pastaland VAT is 22%
>>

Yes, it's VAT plus some extra charges for imports. A 190 eur printer will not have VAT included. If you order parts, they will usually not get taxed, since items cheaper than ~20 eur are exempt from taxation.
>>
>>1089755

Does the wade click?

I had similar issues, my extruder stepper wasnt pulling hard enough to turn my filament spool. It would print fine if there was plenty of slack in the filament, but would fail when tension built up.

Cranking up the power on the extruder stepper driver did the trick for me - worth trying before you shell out for a new extruder set up

anyone have a difinitive Bill of Materials for the original i3 Mk1 and Mk2?
>>
>>1090483
The main hardware difference is probably E3D hotend and new heated bed with bed calibration. As far as I know you can't buy the new heated bed.
Why don't you post pictures of your prints and describe problems that you have. Someone might be able to help you, before you start buying new parts and spending money.
>>
>>1090494
Ah, there's a little more info I didn't mention.

I have to buy new parts anyway - the X-tensioner part snapped (my spare then snapped too) and I can't print anything.

Ordering off 3Dhubs.

Pic related is a pikachu I was printing for a friend.

You can see the wobble, my threaded rods are bent as fuck, so I'm replacing them with 8mm lead screws - again I need to order these parts as my printer is fucked.

After that I intend to get it working well and print myself parts to upgrade or build a MK2 from scratch.

That is quite bad. I can't believe this is just from bent threaded rods.
I don't think there is complete BOM. But this might help you: https://grabcad.com/library/original-prusa-i3-mk2-printer-1

>>1090515
>That is quite bad. I can't believe this is just from bent threaded rods.

Agreed, but when i get the new parts for the lead screws etc. I'll probably rebuild the entire thing.

I also need to make sure my settings are correct (the printer isn't nearby) - making sure my steppers aren't moving fractions of a turn that they're unable to actually achieve. (if that makes sense)

Any tips?

>And maybe you should just consider buying this: http://shop.prusa3d.com/en/printer-upgrades/106-original-prusa-i3-plus-to-mk2-upgrade-kit.html

Mine isn't a stock prusa i3 - it's a variant - so I'd have to mod it back to a standard i3, then use the upgrade kit.

I actually pull a good amount of line out as my jury rigged filament spool can't be trusted to rotate well. That is good advice. I will give that a shot, it can't hurt.

The margin of error you are talking about is so minute its not noticeable in a print. Its done by your slicer
With that said, if your axis steps are not properly tuned, it will move too far or not far enough per each step command given to the printer

Here is a calculator, double check all of your step values.

My interest waxes and wanes on this additive manufacture stuff but I'm trying to get the printer into a working state.

I'm actually a structural engineer.

My MD asked me to find a 3d printer for the firm for less than £1k - I ended up realising that the Prusa i3 Mk2 is the only printer with a decent build quality that isn't 2k+ - so we're going to buy that one.

I'll probably use the work printer to upgrade mine in the new year, but I'm pretty desperate for the broken parts.

Hi guys, just finished assembling my first 3D printer (an Anet A8) today and went for a test print with a fresh spool of PLA.
Since I heard that the stock cooling nozzle was shit I printed this one instead. Just used the standard presets of Cura for PLA at 0.1mm layer height, but instead of 2.85mm plastic I changed that to 1.75mm as my filament.
Also no support material was used.
I don't like how uneven are the layers (and don't ask me why one is missing), how can I improve the quality of my future prints?
Thanks!

I don't have SSR with AC bed yet, but I am thinking about it. As far as I know you are suppose to use Bang bang control instead of PID control. You must change this in firmware. Repetier also has Bang bang control every x second, where you adjust time interval.
I am also looking at Marlin and there are some options suitable for relays, but it still uses PID control and it is in section that is meant for extruder and not heated bed. So, I don't completely understand what you are supposed to do there.

What relay are you using? a cheap Fotek?

Okay guys, a friend gave me one of the original MakerBot replicators, with the lasercut frame. I've been beating my brains out trying to use it, as every time I try to print something or use the onboard bed level program, the printer homes and then runs all axis out to their maximum and attempts to go further, resulting in ugly noises. What the fuck am I doing wrong or will flashing Sailfish firmware help?
>>
>>1091091
From the printer? No. It's compiled.
>>
>>1091283
I might have made a mistake. It says "for heated bed with relay". They probably meant power relay and not SSR.

Maybe pulses are too short and SSR can't respond that fast? That is my next guess. I never truly understood PID, so I can't help you more.

I am choosing between 500W and 750W heaters. So I would like to have a bit more overhead. I will probably buy cheap Fotek 10A-50A (even if it is counterfeit).

honestly I would put more trust into a 5A properly rated one running at 3.5A
than a chinese knock off one with numbers pulled out of their arse running at only 10%
in the end the best option is probably to just spend the 20€ or so on a genuine high current one

and I'm running ~200W on it, doesn't get hot at all even after a long time running, so I'd imagine it could handle 500W. I also tried pulsing it at 500msec and it could handle that without issues, again I think you could probably go lower.

that's more than enough if you don't run your hotbed on it
a stepper will draw ~5W and a hotend ~30W so even if everything would be running simultaneously at max load (spoiler, that will never happen during regular operation)
90W plus some for the electronics would be enough.

Its performing great, for the £150 price of the kit. First printer I've owned, and after climbing the steep learning curve and calibrating the firmware and slic3r, it is working really well.

Constructing it was a bit of a bitch, as i had no instructions. Parts were semi-assembled, so I just went through online instructions for "similar" i3 clones, and fusged it together.

However, I _did_ have instructions. On the supplied SD card. In chinese moonrunes.

Great project, and an excellent intro to 3D printing for the low price.

My main tip would be to design and print a cooling fan for the hotend
