unsuccessfull y-axis selftest (Prusa CoreOne assembly kit)
I ordered the Prusa Core One as an assembly kit and assembled it. During the subsequent self-test, I received a negative result for the Y-axis test. Unfortunately, I have no idea what the problem might be (I made a video of the test).
I can't find anything about this in the manual.
When tensioning the belts, I'm experiencing the phenomenon that the frame tension settings affect each other.

Can't see the video, so this is a bit of a stab in the dark: Take a look at the cable to the side filament sensor. Does it run straight towards the back wall (below the CoreXY frame)? If it got caught in a cable tie and bulges inward a bit, the cable can rub against the Y linear bearing -- enough to obstruct the Y travel and calibration.

That's it... I had to readjust the belt tensioner on the right side because the extruder guide rail wasn't flush on both sides.
The subsequent X-axis test failed again, but simply repeating the tests finally made it work.
Thanks for your support.
