FluidNC Alarm 10

FluidNCAlarmNot a position problem

The spindle controller reported a problem.

Not a position problem. Hamrun's reading: FluidNC doesn't say. If it stopped mid-cut, home before trusting position. (Hamrun's reading)
What to do
  1. Check the spindle or VFD is powered and its cable is connected.
  2. Check the spindle section of your FluidNC config file.

Got a different message?

Paste it into the decoder. Hamrun's editor checks your G-code before you run it, so a toolpath that leaves the machine's travel or a missing feed rate is caught before the machine stops.
