PLASMA NOISE

I�m using the software to run a plasma cutter (gantry
style)

I�m getting an interference between the motors and the
plasma.

If I run the machine without the plasma, it runs very
smooth, but once I turn the plasma on the motors gets
something as an on/off pattern or like a vibration.

The plasma cut is not even, it�s something like a
small zig zag pattern.

I�m running the machine with Geckodrives G201, Pacific
Scientific stepper motors and Microkinetics PWR36
power supply.

What can I do to isolate this problem?

Best regards

Raul Lara
