A hard stop was triggered.

Position is lost: home again. Hamrun's reading: a hard stop halts at once. (Hamrun's reading)
What to do
  1. Find what triggered it (stop button, limit, fault).
  2. Home the machine, then set your work zero again before restarting the job.
Official FluidNC message: “Hard Stop” 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.
