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.

Maybe the inconsistency is in the filament? Could you try another? It could be that the diameter of the filament varies and causes this issue.

Could be, however. I’ve had the same issues with multiple filaments that I’ve used for over a year, however this has only been happening in the last month.

Super strange. Especially as it's only on one side. It looks nice though, if that was intentional I'd be impressed.

Extruder gears are free?

Extruder gears seem free, but I did just notice that the POM wheels on the x-gantry seem to have flat spots in them. This could be the cause so I’ve bought some new ones to test the theory.

That could very well be the issue. Hope it helps and you're back to flawless in no time 💖

Thanks! I’ll update the thread when I test it so there is a log for anyone else who may experience this issue.

That's the spirit. Thanks!
