Ender 3 v3 se slows to a near stop.

Ender 3 v3 SE started having issues during printing. Nothing changed with settings, slicer, SD card or filament. It will print just fine for the first 6 layers or so the it will start slowing way down for no reason and making a beep/humming noise. It also started having under extruding issues and I’m thinking they are related. Haven’t been able to find anyone having the same issue.

Which slicer? I have noticed on thin walls using creality print 4.3.8 on my V3SE it will slow to an almost standstill. If I click on Speed for viewing the sliced model it will show the problem area in blue. If I try other slicers that problem goes. Don’t know about the beep/humming.

I don’t remember what version on creality print I was using but I even had the issue when I used the new 5.0 version. I’ll have to try another slicer and see if it makes a difference.
