Problems after MK3S and MMU2S upgrade.
Hi!
When my printer was just a normal MK3 it worked perfectly.
But after the upgrade to MK3S and MMU2S upgrade the top layer looks weird.
Any ideas?
With regards.

Looks like a bed leveling issue. The ripples from the nozzle height not being correct for the region being printed and overextruding. 3.7 firmware did some changes that affect how mesh correction is slowly removed as the layer stack builds. Doubt that's the issue, but might be part of it (over thinking the issue). It could also be as simple as the part is warping, or lifting off the bed, that now higher edge compressing layers.
Other places to check: are you certain you installed the MK3S firmware? I doubt firmware would cause this... but flashing the wrong firmware has been a common issue.

Turns out it did warp, but was so little that I didn't notice it. Had to check on a flat table.
Thanks! 2 perfect prints after each other now! 🙂
