X Axis layer shift

I reached out to Prusa Support earlier today but I figured I would come here too and share the issue I'm having.

This is the second time this has happened. I bought this printer assembled back in July of this year. I haven't been using it much because I don't have too many STL's sliced for it yet.

I've checked everything the first time it happened and disabled crash detection and printed again and no issues. Thought it was solved. Woke up this morning to a three day print with around fourteen hours left and the X layer was shifted again. I am attaching some images to perhaps help with the diagnosis.

Best Answer by Artur5:

A value of 209 for the Y belt is very low, meaning the belt is over tightened. The ideal value according to Prusas is  275. The X belt is better at 242 but still a bit too far from 275.

Check manually the tension of the belts, specially the Y axis. Can you squeeze them easily between your fingers ?

RE: X Axis layer shift

On the print above, did you have the crash detection on or off?

I had crash detection off. I had an issue before and read somewhere to disable that. Thank you for the reply.

I have made some adjustments. An individual from Prusa support mentioned the same thing. Right now the values are hovering around 250 on both X and Y. Perhaps I'll tweak it some more then. Thank you!
