Hi all,

H have a home made plasma table running Mach 4 with a Warprunner THC. The THC is new to the machine. I believe I have my Warprunner wired correctly, but it's misbehaving, it dives and...

I'm a home hobby user with a home built plasma table. It works great, no real issues. I recently added the Warp 9 Warprunner THC and I think it's working correctly, but I'm finding it might be more...

I'm 99.9% sure I now know the problem. I'll verify tonight, but the problem must be low voltage from the power supply. The ESS wants only 5 v, but the Warp runner needs 12-24v. I was only giving...

I think my old THC 301 plasma interface board had 2 different (optional) ways to detect ARC OK and I incorrectly wired them both up "Belt and suspenders". So I don't think I ever needed the HECS...

Hi all, I have an old Hypertherm Powermax 1000 on a home made plasma table. I recently upgraded from Mach 3 to Mach 4 and my old THC did not seem to have a plugin for Mach 4. No problem, I...

I just got my old homemade plasma cutter running again. This time running using Mach 4. It's running great! Video link below shows it making it's first project under Mach 4 control. I have a...

Well, my decision is made. For now at least. the machine is going back to Mach 3 to get it back online. I'm going to try the Physics Anonymous screen set. Then I'll play with Mach 4 when I get a...

Hi Pete,

I'm very interested in your experience, Please share! The software looks fantastic, no doubt the support will be top notch! I called there yesterday and spoke to Dave who I believe is...

I was all set to order the nighthawk, but now you guys have me worrying about these missing functions. Is this really a problem or just a theoretical problem? I do need to het a part cut, so I...

Hi Roger,

I'm really considering the Nighthawk controller from CNC3D once they implement Inches in there Commander software. The UI looks pleasant, modern and much easier to use than Linux CNC or...

I was definitely on that forum and there are some absolute geniuses there that really try to help. I'm just a fish out of water in Linux. I did get the basics working, but with nothing but constant...

Hi, I a home hobby user, no revenue, just for fun home shop projects. I have an old Bridgeport BOSS 5 that was setup with Mach 3 with an Ethernet Smooth Stepper. I have a 4th access rotary table...

Yes Mach 3 absolutely works, but for how long? I just expect some windows update will kill Mach 3 for good. If the PC didn't crash, I'd keep running it, but since I lost my licensed screen sets and...

I recognize the clear advantages of the metric system and I've tried to work in it when I first got into 3d printers that like metric, but old dog syndrome kicks in. I just can't visualize what 13...

Commander & Nighthawk look very interesting. I've never seen this option. Watching some videos on it now. The software sure seems more modern and the software seems to be free so there should be...

Thanks BOSS5 for your reply. You are correct. I did already replace my motors with the new NEMA 42's while I picked up a bit of performance, it was probably not worth the effort and cost. While...

On a friend's recommendation I changed the setting in Mach 3 to "CV Mode" and I doubled the speed on the helix. It still can't go more than 16 ipm on the Helix, but it's better than the 8 ipm I was...

Couldn't get the time off from work to go to the workshop. How was it? I really wanted to go, but need my job more. Hopefully it was a success and they will do another one next year. I do have a...

Thanks Mike. I'm sure this is a nice vice, but only opens to 6". What makes this type of vice better than a Kurt 688 which opens to nearly 9"? There has to be a reason these smaller capacity vices...

I have two Bridgeport's one manual step pulley machine and the other is a Boss 5 CNC Machine. I've had a Kurt 688 vice on my manual machine for many years and love it. I have a "CNC vice" on the...

Steve, I tried both the inrush current limiter and the MOV's across the contactor. No Luck. I'm now dealing with the interference problem by using an Ethernet smooth-stepper and relocating the PC a...

Steve,

Yes, I'm switching the AC main on the primary side of the transformer using a magnetic contactor (PMDX-Contactor18-120). I've seen some posts about adding a capacitor to to solve this....

This problem seems to be worse in the cold. When the motors are cold it may take 3 or 4 restarts until it starts. Once it starts (goes ready with no fault) it's good and does not fault while...

I have another issue with my new plasma table. My setup is new so something could be wired wrong. I have an intermittent fault on power up. Sometimes it faults most times it doesn't. If it faults...

I went through my pile of parts and found an identical motherboard. I swapped it in and got the exact same result. Strange, 2 motherboards with the same problem. Motherboard design flaw perhaps? ...

I swapped out the drive and still no luck, so I swapped parallel ports. I put the Gecko on Port 2 (intended for my THC) and everything works. So the problem is with the parallel port on the...

Great,

I'll give that a try. My parallel cable theory did not pan out. I swapped the cable for a different one and no joy. I suppose it's possible it's the port. swapping Y drive with A drive...

I'm building a plasma table based a G540 that I won at last years Digital Machinist CNC workshop in Ann Arbor. Thanks for Donating it!!! Such a nice small form factor, seems perfect for this...

I'm building a stepper motor based CNC Plasma table. We can skip for now the stepper/servo debate and stick with stepper.

I'm using NEMA 34 motors from keeling. I could not find the max RPM on...
