Y-Axis test fails. Bearings hitting ends, but still wanna continue
You can see in the video that the bearings hit the bend end, but not smoothly. Seems like it wants to continue a few milimiters, but it bounces off at the end and the test fails.
- Checked the belt tension, seems fine. Followed Prusa guide.
- Re-reposition the left bearings, but still the same.
- Tried and older firmware and the same. Running 6.0.2 now.

RE: Y-Axis test fails. Bearings hitting ends, but still wanna continue
Have you checked the screws holding the pulley to the motor shaft? Had a similar problem a while ago with the y-axis test failing, turned out the grub screws became a bit loose and the pulley was slipping on the motor shaft.

Thanks! It was the belt tension. The Prusa support was really awesome and helped me with that.
