Extruder "skipping" during brim printing

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?


Hello Gary,

Do you mean printing raft? as Cetus software does not have option to print brim.

Is it too close to the print bed?
