FluidNC Alarm 15

FluidNCAlarmPosition isn't set yet: home first

FluidNC is starting up, or its setup didn't finish.

Position isn't set yet: home first. Nothing has been homed yet. (Hamrun's reading)
What to do
  1. Wait for startup to finish.
  2. If it stays here, read the boot messages (look for lines starting with ERR) and fix the config file.
Official FluidNC message: “Init” 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.
