grblHAL Error 15
grblHALErrorPosition is kept
A jog would go past the machine's travel, so it was ignored.
Position is kept. An error means the controller refused that one line or command, so nothing moved for it. (Hamrun's reading)
What to do
- Jog a shorter distance, or jog the other way.
- If the machine isn't homed, home first so it knows where its limits are.
Official grblHAL message: “Jog target exceeds machine travel. Jog command has been ignored.” 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.
