Just recently, I noticed that my Cetus extruder has started skipping (grinding) but it ONLY does it when my printer is printing a brim. So far, it has never done it while printing the actual piece I'm working on. I've releveled the bed multiple times, removed the filament and ran a cleaner filament through the nozzle to clean dirt/clogs out. But, it still is doing the same thing. Has anyone else seen this? If so, have you been able to correct it?
I might also add that I did update the software when an auto-update notice popped up. Could that be the problem?
