@Tommylight - I have my Proma 150 wired up as Proma directed; negative to the torch, positive to work clamp. I've done all the wiring internally on the plasma cutter to reduce wire length and HF interference.
@Islander261 - I have no clue how to deal with the portions of the code that have question marks next to them. I don't even know if all these are supposed to go into the machine HAL. I am assuming as much, but more complete instructions are necessary for my skill level.
Just a quick peek inside my (grounded) control box
Use a shielded cable from control box to the Proma THC, grounded only on the control box side.
Use a simple relay for the probe switch, powered from the same power supply as the drives ( assuming you are using 24V ), or if you do have a 5V one. The probe switch should just turn on that relay, nothing else, the NO side of the relay should be wired to the input of your mesa card. That will eliminate all the interference from the cable going to probe switch.
As a side note, i refrain from putting the Proma THC anywhere near the plasma, i use double shielded cable to wire the output voltage wires to the proma. I am fully aware that if those two wires come near each other all hell will break loose the instance the torch is fired.
I would advise to move the voltage cables from the output terminals and rewire them as near as possible to the capacitors that are used to protect the rectifier inside the plasma. That will help a lot in avoiding interference.
@Tommylight
I'll swap over the proma to the controller box and run a shielded cable to it. I'll see what I can do about adjusting the mounting points of the the voltage cables for the thc, it's a pretty dense unit and it was pretty difficult to get them where they are currently.
My float switch is normally open and I have my relay setup (inside the shielded controller box) as normally open, with pins 13(-) and 14(+) triggering the relay. That would be => hm2_7i96.0.ssr.0.out-00
@Islander261
I think the problem I'm having is understanding the actual inputs of these individual components. I'm going to have to read that source and see if I can make heads or tails of this code.
Hahaha, yeah I stuffed it all into a galvanized steel box until I can get a PC case. I'll tidy it up a lot more here soon.
I'm putting the entirety of the THCUD files (that aren't specific to postgui & xml) into a custom HAL, will that negatively affect the program running?
