Can you only run one stepper at a time and see if a specific one(s) is causing the issue? Maybe it's physically closer or has a better line of sight to the CPU?

- fxtentacle 1y agoIn the end, I acquired an EMI probe. The DC +48V cable from power supply to spindle was emitting lots of interference. I had not really considered it because usually EMI is generated by changing voltage and in theory that line should remain at the same voltage. But it seems like tiny sparks in the spindle (or something like that) will momentarily drag down the power supply line, thereby causing HF emissions.
