Yup first thing I did. Stuff the compressor tanks in the rafters and ran plumbing back to the pump and motor on the ground. In a cabinet. Best thing is that the extra plumbing acts as an air cooler helping remove water from the air.

Okay this is fun. So first of your amp reading is no Bueno. As I can tell you have no real load on the circuit so your amp draw will be low. Until something acts as a load like a light bulb contacting the frame and the neutral line or your hands. So the amp will rise.
Now the next thing there is power going to the motor, with out the foot pedal engaged?
A quick hunch makes me say is the new foot pedal wired backwards? On ac circuits it’s you cut power at the switch and the rest of the unit is connected to neutral line all the time.
Those sowing machine motors are typically “universal motors” they are brushed motors that can run on both ac and DC. So power flows from footpedals to brushes to armature, to windings back out the other brush. It’s a bit on the weird side that the shaft has voltage. It could be from a brush sitting funny maybe. But I would most definitely just check the wiring orientation for starters. Then go from there. Adding a ground connection isn’t a solution. A ground wire is to prevent you from getting hurt when this happens.

Don’t waste your time with ignorant little shits like that.

This is so wrong it’s absurd. I work on machinery. Heavy equipment, I’ve dicked around with industrial robots and hell I even have and use a 3 axis cnc mill from 1986.
Most of the stuff that’s out there is reliable as time with very little maintenance required. Oil or grease movable joints. Top up oils, change oils every 1000hrs. It’s not hard or expensive to keep up on maintenance. Pay a premium and replace gear oil with PAG type oil, and you will never have to change that oil in your life.
Machines just work, they don’t have feelings, they don’t take sick days, they don’t take lunches. And why they fuck are you buying equipment with out way to pay it off first. Build it, and they will come. It doesn’t work all too well when everyone and their grandma has a cnc shop these days.

I got a bit excited, because I have a 40ft with the exact same set up but with steel. To store round bar stock, pipe, square tube etc for metal work. It even had an over head crane to move stock in and out. It was awesome until some fuck decided to back an excavator into the front doors and sides. Mangled the whole thing to shit.

That’s right. Every tool is a lathe one way or another.

Yes but now the fire place chanel is just that more emersive. Also I keep our plasma in the bedroom. On cold winter nights it makes things cozy.

Don’t feed the dipshit troll. It is trying to get people bent out of shape with a long-term agenda.

Bud, you’re stuned. It’s bad, its fucking up kids. You are in denial flat our running the tobacco playbook.

Yeah, open tub fermatation is safe. The yeast out competes everything else in the tub, not really giving any other microbes any chance to form a colony.

Is this a joke? Like actually? If your speaker wire is “rusting and failing” I got bad news for your 120v/240v service and plumbing.
This is just dumb.
Also who the fuck would rip out celling and walls for low voltage speaker wire run. Being a bit dramatic there bud. Just use the old shit to pull the new wire through. Cut small holes where you can’t.
- Comment on So how would you handle this? 3 months ago:
Battery bad… 120v ac good. Just one wire in the hot side touch one screw. Put it on a random timer, too , this way when they say it’s shocking it everyone else will think they crazy.

Plasma is made from basicly over charging a gas with electrons the gas getting all pissy about having those electrons and starts dumping them. something do with elements wanting stability. In that process you get alot of heat out put. Now f you make it more dense I would conclude simply, you now have more ionized atoms in the plasma stream, meaning your plasma will be hotter if the stream will be the same size or if the plasma stream is shrunk but has the same number of ionized gas atoms, you have the same heat out put but in a smaller stream.

Well I would start of by testing the shit stained components on back bottom right. That looks to be the most significant amount of damage.
Or you can do it the good old read the smoke signals. And force power in to by putting a bigger fuse and letting the part that’s fucked burn up and show you the way. But you kina only have one chance at it.
What is the load on the relay?

I fucking love it! I have been there so many fucking times to the point of putting a hole in a wall. Best part is I’d give up walk away for a month or so then literally turn the stupid fuck on and press print and it would print just fine. I just use glass on one printer and carbon fiber on the other. I had pei once threw that shit right in the garbage. A good scuff with 80 grit sand paper on both and wash off with rubbing alcohol. I did have an issue once with a bent touch probe that would fuck my z offset so the first layer wouldn’t actualy be low enough.

Oxygen isn’t flammable.
It just helps other things become ashes faster.
