Y axis length failure
what would cause a 'Y axis length failure' on the selftest. There is also a strong clicking sound. What is the solution?
RE: Y axis length failure
The bed must move 210 mm; easy to measure. Manually slide the bed to the front then to the back, it should move 210 mm, or a bit more. Anything that prevents that range of motion will cause a failure.
Bearings installed wrong; cable ties positioned wrong (the build instructions are very clear); cables routed where they interfere; U-bolys installed where they interfere (very close tolerances, any positioning errors they can hit the frame); etc.
Another common cause if the motor drive gear is not installed correctly, or a loose belt.

I retightened the screws on the belt mounts after moving one a bit more to the far side to stretch the belt. Now its working!
many thanks.
