here are my config files for the machine
Due to the problems I have disconnected the motors. As a test, I had one motor rotating freely on the controller - no difference. I now have an oscilloscope and can check the output of the motor signals if necessary. Currently, only the Ethernet cable and the power supply are connected to the Mesa 7i96s.

Created with PnConf Standard with minimal settings. No limit switches and no sensors. Settings for my JMC cl stepper (microsteps, 5mm/rev ...)

Maybe I have a fundamental error in the configuration? 

 

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
