Turn on the printer,
. The printer head starts moving, follow with grinding rattling noise
. Then, the screen displays " Homing Failed: Printer Halted - Please Reset "
All the helps are greatly appreciated.
Need more info on “starts moving” does it move up, down, left, right, forward?
Which axis is grinding?
Off hand, I’d say you’ve got a failed limit switch on the X or Y.
Or post a picture of where it is stuck and grinding?
…
As per advise from LulzBot supports, it’s wiring issue with partial connection somewhere (?).
From my first attempt, I did unplug and carefully re-plug every connection point that relates to the X-axis/motor and the concern is gone.
Many thanks for your great supports!
