Problems with the Y-Calibration
Hi,
Got the Prusa core One Kit and assembled it and now got down the rabbit hole in fixing this calibration error for Y. The thing is that I‘m not sure where to look next.
X and Z worked very well. At the beginning got issues with X because of the belt tension.
used the app for the belt tension. Checked nearly everything (with what I found in the forum). Not sure where to start next.
maybe you can see something on the video - or if not, where to start troubleshooting.
got a second Core One and this works fine without issues in the calibration process.
I hope that you can help with this. Thank you!

I’ve got the exact same problem too! It also is happening when unloading filament and it attempts to ‘park’ the extruder. My new printer is just junk at this point.
RE: Problems with the Y-Calibration
Check to make sure your gantry is still parallel to the frame. Release the belt tension so it is slack. Move the gantry all the way to the front and check that it hits the end blocks at the same time on both sides. If not, then use a wrench to pry the opposite side and then slightly manually bend the side with a gap it until it is square. When retightening the belts, ensure it's done slowly and evenly or can end up bending the gantry out of square again.
If the gantry is already squared, then check under the left hand side rail that the bearing is not colliding with a loose cable

also consider getting in touch with Prusa's support. It may take long but they will help
