Layer shift on Y axis after mmu2 upgrade
I had a perfectly working MK3 which I recently upgraded to the mmu2. This included a firmware update to 3.7.1.
After this upgrade I'm now getting weird layer shifts on the y axis at the beginning of every print.
The upgrade had no changes on the y axis and I've checked the belts, both y and X are fine.
Any idea what's causing this?

RE: Layer shift on Y axis after mmu2 upgrade
I have the same problem I think. Went from MK3 to MK3S + MMU2S and ever since my print quality has been terrible.
The reading for the Y belt tension was very high but I can’t get it below 275. I tensioned it to the point that I worry about the tensioner breaking. The X belt reads 250 but it’s way looser.
(Print in the photo is Prusa PETG but the layer shifting occurs with every filament I’ve tried so far)
