Print layers not cooling properly


Recommended Posts

Posted (edited) · Print layers not cooling properly

Lately I've been having trouble with pillowing and ugly overhangs on my print models. My impression is that the layers are not cooling properly. I replaced my side fans and reinstalled Marlin to see if it changed anything, but nothing has changed.

 

I am weirdly suspecting that the side fans start spinning faster after the print job is done. I can sometimes make out the circle shape on my fans during printing, but when the print job is done, the fans are spinning so quickly that I can't make out the circle shape. I have the fans set to 100% during printing.

 

The pink calibration cat was printed before these problems began. The orange cat is from today. All of my calibration cats look more or less like this right now.
