FluidNC Alarm 17

FluidNCAlarmPosition is kept

A G-code error while running a file raised an alarm, so the job stopped.

Position is kept. Hamrun's reading: the controller stops on the bad line before moving for it. (Hamrun's reading)
What to do
  1. Look at the error just before the alarm: it names the problem line.
  2. Fix the file (or the post-processor), unlock and run again.
Official FluidNC message: “GCode Error” source

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.
