Z Axis self test failure
I can't seem to get past the Z axis calibration. My XL came with FW 4.7.1, but I have tried with 4.7.2 and the 5.1.0 alpha firmware and have the same issue. The Z motors were pretty quiet when it was homing to the top of the Z axis, but it made some noise when going to the bottom. This seems to have been resolved with a bit of grease on the Z axis leadscrews. How can I get a more detailed error message as to what is happening? It doesn't seem to give me any error aside from the X next to the Z axis test which isn't helpful at all. Video attached for reference.

There was a small ball bearing underneath the spring steel sheet very close to the right z motor that was screwing up the calibration. Chat support was super helpful getting this figured out. It is much harder to tell on an XL if there is anything underneath the spring steel sheet due to the semi enclosed design and just how big the build plate is. Need to be extra diligent to make sure the heated bed is free from debris before putting the spring steel sheets on.

Found this article:

It says there is a menu with diagnostics that doesn't seem to exist:
Selftest results
During the selftest, its results are shown on the screen, indicating success or fail for each point. Alterantively, the results can be shown at any time on the following path: LCD Menu - Calibrate - Diagnostics - Show selftest results.
There is no Diagnostics menu to be found.
