I’ve been a happy 350 user for 2 years, now mid print I’m getting y axis shift at every layer change, tested y rails without bed attached, both move together and home properly, tried multiple slicers and multiple models, going to try swaping the rail junction boxes next. Anyone got any more ideas?

Have you checked the bearings for tightness? Is the bed wobbling up and down as it moves?

All seems good, I’ve just done a full factory reset and it printed the test cube beautifully, I guess some code must have got corrupted with our shitty power network brownouts we’ve been having lately. Here’s hoping it’s all good again now.
