Help with intermittent extrusion issue (imgur.com)

Normally slopes on my prints look fine, but recently I’ve been getting bad extrusion on some prints but not all. Same materials, same print file. Could this be one of the motors starting to fail? Printed on an ender 3.

Edit: so changing the POM wheels did nothing. However, I did notice while printing the layers weren’t cooling as much as they should before the next layer started. So maybe there could be a fan issue.

Looks like a weird extrusion issue, is your ender 3 completely stock?

It has a Bigtreetech SKR mini E3 V3, but stock otherwise.

Have you checked the extruder arm? They tend to crack. Although this looks more like overextruding rather than under, which you would expect if the arm was cracked. Still worth to check it out though
