Hi,

I haven't been around here in a long time, and to be honest I haven't used my crappy old upgraded CNC3020 in ages. Anyway I had a little job to do, so last night i went and fired it up, everything seemed to be working ok until I turned the spindle on, then the Y axis started moving about on it's own.

I have tried a few things but not sure where to go from here...


  • Swapped the axis cables at the back of the panel, and it was still the motor plugged into the y stepper driver.
  • Swapped the stepper controllers over and still the Y Axis.
  • Swapped the data cables on the BOB, still the Y axis
  • Rerouted spindle wires as far away from anything else as possible.


In case it's relevant the Y axis always seems to move in a positive direction.

Regards,

Les
