Nomad 3 unable to initialize, homing failed after power trip

Hello,

I had been using my Nomad 3 for awhile but recently a power trip occur and the machine seems to forget its setting/configuration.

When i tried to initialized, the machine shown the following error “GRBL Alarm 6: Homing fail. Reset during homing cycle.”

I’ve tried both $23 and G92 after moving the spindle to the top most right corner for zero-ing.

It still doesn’t work. Anyone had the similar situation or know the solution to this?

Verify nothing is mechanically interfering and that the machine is well-lubricated.

Power down, move the machine to the middle, then power up, connect, go to Settings and test each homing switch — does each present as the correct input?

If there’s nothing obvious to address and it still won’t home, check in at support.
