Hi Guys.
Well the problem is i want to retrofit a plasma, current motors and electronics are not working correctly.
I will put NEMA 34 whit a 1:5 gearbox -> rack and pinion , only on X,Y axis, Z will be driven with a NEMA24 (using the existing lead screw)
Still not sure , open loop or closed loop steppers (more cabels more chances of EMI)
So all I/O <-> (HOME ,LIMIT , THC , USER BUTTON) will be optically isolated with a relay and additional optocoupler (machine <-> MEASA )
The current setup has an braded cable sleeve around the plasma cable in a drag chain besides all the other cables.
My question is what should i do about HF/HV arc start of the Hyperterm max 100?
I know grounding is imperative. The CNC electronics box will well away from the plasma transformer.
Add an aditional ground rod?
Kind regards Marko
