i don't see a schematic for the v6 hotend on google but assuming the heating element is being pwm'd by a switch i see three possibilities. one is that the switch controlling the heating element is damaged and leaking. another is that it's inadvertently being run at a low duty cycle by bad code. the third is that the gate or base circuitry of the switch is being pulled weakly to one rail by contaminants on the board.

measure the resistance across the switch when everything is off. it should be 100k+. if not you have a broken switch. otherwise measure the voltage across the heater when the system is on but not heating. it should be near zero. if it's not then the switch is fine. use the duty range on your multimeter (if you have one, otherwise voltage) to measure between the gate and source (base and emitter) of the heater switch. should be 0% or <100mV. if duty isn't zero it's a software issue. if the voltage is above that level and your board's not contaminated then the problem gets interesting.

if none of that is wrong then just kill yourself or something.

thx ill try tomorrow.

Use the right thermistor table in the firmware and do a PID autotune again.

it's stooopid coz you gotta be real careful with it so jack doesnt break. ideally you should be able to rip them off your head, and throw them on a hook in a single fluid motion, like jack might do with his hat.

I don't know how small your garage is but cover the timber with sheet metal is fine
Just check after you finished your work that nothing is cooking

>>1222941
Timbers aren't all that flammable. They would need a horizontal surface for hot material to sit on to be a serious fire risk. Sheet metal should be plenty so long as there isn't a gap at the bottom where spatter can lie against the wood, and the wood itself is smooth and in good condition.

Most stick and MIG spatter stops within a few feet, but occasional bits might travel 20 feet or more, especially if the floor is sloped. TIG is generally not a spark/spatter risk. If you're doing stick or MIG, clear the area well around where you'll be welding of any flammables, especially things contacting the floor. If that's not practical, check back periodically after finishing welding to make sure that nothing is smouldering.

A bigger concern is probably ventilation. Welding fumes are bad for you, so get a fan if the open door isn't circulating the air enough.

They should be fine. When I was a kid I was welding up a gokart right next to a can of gas. Make sure you have good ventilation for fumes.

1 month is too short a drying time. Come back to them in a season or 3. Google how to dry wood and learn how to set them up so they won't warp so much while drying.

several woodworking books I have mention one year drying time per inch of thickness

If you've got a fuckhuge microwave capable of holding it, you could try sticking it in a plastic bag, heat up for 2min at a time, empty the water out and repeat until dry
Until then, you got a while to wait

>It leaks in from the kitchen door and the back door when the outside water level gets high enough
there is standing water outside/up against the building?

>>1222779
Kinda sorta. Most of it is runoff from the neighbor's driveway, which falls into the path along the side of our duplex.

You are living in like feet of mold.

You need more sand bags. If you still want a pump you need a generator too

Here are the bikes that will be merged into one to hold the motor. The blue one belonged to my grand parents and the red one was taken from a junk pile.

>>1222743
Toss the chain for sure. there's no coming back from that. Besides that.. the shitty chrome on the muffler [wasn't real clearly] just clean it off good, and use some high heat paint on it. Piston and head look good and clean, at least the sides I can see, if the gas tank has nasty rusty shit inside, just clean it good with what ever you think will work, and coat it with POR 15. the shitty china motor's carb jetting is normally really fucking off, so plan a small rejet.

but nice blogpost.

>>1222909

That's really what I was going for, just need the best methods to clean up the metal before reassembly. This is my first time screwing with a 2 cycle.

fire need air, fire hot, fire burn

might have originally had a collar that allowed to adjust the air flow

Like the collars around the openings here in pic related? Making a new one seems easy enough

I'm canadian so trade requirements may vary, but for drainage all you need for height is enough for 1/4" drop per 1' off the p trap. And even that isn't necessarily mandatory.

For water supply lines, if you use PEX and sharkbites you'd be go to go.

Do you have any previous experience in plumbing? and/or own a crimping tool for PEX?

>>1222588

I don't have any real experience beyond fixing toilet leaks and cleaning p traps. This seems like a simple enough job for a noob because I'm literally just going to install y-fittings at the cold water supply valve and drain and run a line for each along the wall to the sink, which is going to be a plastic basin with a supply valve at top and a drain at bottom, all sitting on a structure made from 2x4s.

>>1222588

Forgot to add thanks for the info on the slope. I will look into how to work with PEX lines and sharkbite fittings

I don't know much about dyeing cloth but I know about mixing colours. if you dye purple over teal it will probably look kind of muddy. the middle part where the two blend probably won't look too bad, but as the purple gets stronger, the red in the purple and the green in the teal will make it look a little brownish. for the brightest colours you should start with white cloth.

>>1222268
>thanks buddy

>>1222268
i didnt think to think about the purple make up with the reds and what . good point

>>1222141
I would try to determine the maximum continuous discharge current determined by the battery manufacturer and then cross reference it with your discharge C or E rating.

Yay math!

>>1222141
I really hope you meant +9V not -9V.
D2 might be reversed. It can be omitted if you promise to never reverse the battery.
Q1 might be mis-connected. Different type numbers may have different pinouts. Check datasheets and ensure yours is correct.
Otherwise, start taking voltage measurements around the circuit and note them on the schematic so you have something to ponder while the battery cools down.

>>1222141
this exact thing has happened to me on a pedal build before
a reversed diode to ground was the culprit

Those shits don't work as deodorant.

I say this as a working man who is married to a woman who is addicted to doterra. She makes all kinds of things that do work wonders, but deodorant is not one of them.

>>1222013
Than may i ask how can i make those shits work as a perfume?

The watt rating is for how much watts the resistor will endure before it blows up. So using a 1W resistor in place of a 1/2W is good, using a 1/4W resistor would be a no go.

you can make good money in HVAC if you have your own company, even if it's small. Hang in there pepe.

hvac is the walmart greeter of mechanical engineering

FACT

>>1221839

HVAC techs actually make more than $15/hr, MEs don't.
