My PM45 won’t cut through 16 gauge steel at regular speeds. It fires, but cuts half way through and blows slag all over the place. You just get an 1/8” wide melted grove in the metal. It’s at the...

The X axis on my plasma cutter has stopped working intermittently. I have a 4X8 plasma table. X axis is along the 4 foot gantry, Y runs the 8 foot length of the table. It started developing a symptom...

Thank you. That totally did exactly what I wanted.

And thanks to everyone who responded. I don't think I made it exactly clear that I'm rotating the pipe (x axis) under the torch and the torch...

I built a tube cutter attachment out of the headstock of 9x20 lathe for my CNC plasma cutter. I can cope pipe with it all day long. I know there's a coping calculator on the internet and I've used it...

I'm only guessing here, but I suspect the thinking is it could cause the bearings to arc as they turn, but I also suspect that would be much more of an issue with rotary welding than plasma cutting....

The ground was on the table. And the pipe is resting on a metal cradle I made for it to ride on, which is bolted to the table. I powder coated the individual parts of the lathe headstock and...

I used the gears because it just happened to mesh with the gear that was already on my stepper. It was like providence. :-)

Thank you. I think that's where I eventually ended up. I jogged the motor one complete rotation and noted that it came out to something like 5.23 inches. I took the steps per unit, multiplied it by...

My first cutter had a Thermal Dynamics plasma cutter on it. Stay way from those. Get a Hypertherm. The Thermal Dynamics machine ate consumables like no tomorrow. It cost a fortune run. I love the...

This is one of those situations where you get out the same quality you put in. You just have to learn to create vector drawings and some kind of CAD program is your best bet.

I actually hand draw...

So I was cleaning the shop and wondering what to do with this 9x20 lathe I picked up for spare parts. And it occurred to me, that's practically all the parts a guy would need to cut tubing. The gears...

So, to answer my own questions, "Yes! It will work!"

Of course, it wasn't quite as simple as KMtronic's step-by-step instructions made it out to be. I had to install several windows component...

How about this.

I buy this One Relay Controller off ebay: USB One Relay Controller RS232 Serial Controlled | eBay

I follow these instructions to install it: KMtronic USB relays from Mach3 -...

Yes. Twice. I'm on the third computer system. I've replaced electronics. I've removed software updates, I've installed software updates. Yes, I've called support. Yes, I've followed their...

If I wanted to fire a relay to fire a torch out of Mach3, how would I do that?

Let me explain. I have a 4x8 table I built. It's a Precision Plasma gantry machine, PM45, with CandCNC electronics. ...

I used a Cutmaster A40 for about 3 years. I'm glad I got rid of it. I built a new machine and put a Powermax 45 on it. It's worth its weight in saved consumables.

I'm getting anywhere from 5 to...

I understand that it shouldn't rise, but it often does anyway. 18 gauge gets springy, warped, and all kinds of fun stuff. So when I say "rise" it's not supposed to, but it does anyway. It will do a...

I haven't yet, but that's because I just requested to join that group. Just waiting on replay for access.

I honestly can't say if the arc ok stays lit or not. It happen for such a short bit of...

I've bought a PowerMax 45, a gantry kit from Precision Plasma and BladeRunner electronics from CandCNC.

I've built the table. Everything is fine.

I've installed the motors and software. I've...

I usually cut a lot of 18 gauge cold roll. I also cut a lot of 16 and 14 gauge hot rolled. I sometimes cut 12 and 10 gauge hot roll. Every once in awhile I'll cut 1/4" sheet, or cut holes in 1/4...

I bought some mig welder nozzle gel that people use to prevent splatter buildup just to see what it would do. I put some in a little dish and after each row of parts (9 parts, 81 piercings, about...

The control box only stopped once last night, but when it did, two things happened. Because the J6 jumper is gone (and smashed with a hammer), Mach stopped on a dime along with it, which means it...

J6 jumper is gone! Mach won't budge unless the motors have power. Nice. Thank you.

I'm going to assume the error code status lights are the 6 LEDs located in the blackbox above the label "PWR...

I'm going to include a link to a youtube video I made. I was hoping someone might be able to help me out.

The video contains two clips illustrating two different problems.

I have the A40 and the thing bleeds tips and electrodes. One tip and electrode may last a full sheet of 4x8 16 gauge hot rolled, the next set might last half a sheet. A full sheet being around 2,200...

I cut a lot of the same parts over and over. Like 200 of this or 400 of that, so I've considered creating a custom-fitted set of slats that would allow the torch to cut without hitting the underlying...

I've noticed while cutting the voltage can spike around corners to as much as 108v with the target being 95v. If I'm understanding it right, with a target of 95v, anything over 104.5v would be over...

Everything looks fine with the ground. I think I tried using a shield cap once before, but it didn't work out well. I don't remember why. Probably just wasn't setting it up right.

I changed to a...

Cool. That's much easier. Thank you.

I run into this sometimes while creating drawings to be plasma cut. I'll draw in the top view port, but sometimes end up with curves on different z locations.

My solution: If you have some curves...
