I'm using:

  • Workbee CNC
  • SKR1.4 Turbo with TMC5160
  • Marlin 2.0

Steppers suddenly disabled during job. But, they get back working as soon as you restart the machine.

I've had the problem twice with this setup. Once with the Z-axis and once with the Y-axis (that uses two steppers, one keeps on working while the other was disabled).

When I had the problem in Z-axis, I decided to lower current on that axis from 2 A to 1.9 A. It's already 1.5 A for both steppers on the Y-axis.

Just switching off and on the machine is enough to let steppers work again say it seems not to be a wiring problem.

Any clue? Any advice is welcome.

I think I fixed the problem.

Marlin was configured in hybrid mode with stealth chop mode at low speed then spread cycle when the stepper goes faster.

I removed stealth chop and set spread cycle at any speed and it seems to be OK.

I could let the machine work for hours with no issue
