I would like to know what's inside the Proma 150, the technology and why it's so expensive for a piece of equipment that does very little. After voltage dividing I don't see why it's costs so much?

FYI, the video says you connected the up/down to inputs 1/2 but you’re actually wired for the default of 2/3 (pins 11 & 12). Pin 1 is the Arc_OK, which I’m curious about because yours appears to be pre-wired - where are you getting that signal? Ours was not pre-wired, and Mach3 wouldn’t run a program with THC enabled until I wired from the Proma’s Arc_OK output to input 1 on the interface board. Then… for reasons we can’t figure out, Mach3 ignores the THC up/down requests. We can see them in the diagnostic screen, but the PC will not adjust the Z height in jog mode or during a program. We overcame this by checking the box in Settings | Pins | Milling to Use THC input regardless of THC being on or off. Now the THC works during a program, but during jogging / manual cutting it will only adjust up, not down. Seems like a bug.

Yes you are correct. My mistake. I just uploaded a new video with some more information. For the thc to work it needs three arc signal. I pulled direct from the cpc on the machine. It's an open closed signal needs one ground and one to an input

@@practicalfabricator Thanks! Yep, watched that new video a couple hours after you posted it. We’re on the right track with the wiring, but can’t solve the Mach3 behavior completely. The Milling setting seems to essentially say “ignore the THC on/off selector and force it on always”. This probably isn’t an issue in practice, if that’s what it takes, but seems to be working around a bug. We’ve seen videos where this is working normally, but can’t tell how our Mach3 setup is different.
