Y-Axis Shift (and then back again!) during print

2 times this has happened, see the photo which describes it better than words.   Does anyone have any troubleshooting advice?

ASA Prusament Material with Prusa-standard temps, printing in an enclosure 35-36C, 20% RH.  MK3S with 6 days printing time.

TIA!

Looks like a loose grub screw on the motor belt pulley. Alternative it could be the belt skipping a tooth and back again.

Have a look at my models on Printables.com 😉

Thank you for the replies, I've re-installed the Y-axis pulley and refit the grub screws.  Hopefully that was it, it seems intuitively consistent with a shift-then-return behavior.   (belt is clean and tensioned properly, no visible wire issues, etc...)

Thanks again!
