I have searched the forum for help on this but did not see much advice. I am seeing repeated clogging during prints. All my printing has been with Snapmaker-supplied PLA so far. I used one reel of black with no clogging issues. I have started a reel of white and printed a temperature tower successfully. I started a bigger print (about 40 hours I think) and the nozzle clogged about halfway through. I cleared the clog with a thin piece of wire (one tip I found in these forums) and printed a calibration cube and a small mechanical part succesfully. Those successful prints represented about 4 hours of work I think. I started another long print and the nozzle clogged again after about 8 hours. Again I could clear it with a piece of wire and I can easily push filament through by hand when the nozzle is above about 190°.
1: The hob gear that drives the filament has a bit of PLA debris in it after grinding on stuck filament. Should I be trying to clean that out somehow?
2: Is there anything different about the white PLA compared to the black that would be causing clogging? On the temperature tower I printed I didn’t see much variation in quality between the rungs.
I’m printing at Normal quality with zhop and retraction, a skirt, extra extrusion and slower motion on the first layer. I have tried printing at 200-215° so far with the white PLA.
The PLA reel goes into a dry bag between prints to avoid humidity buildup, and it is not in a dusty area. The packaging for the reel was first opened about 4 days ago.
Any tips will be appreciated!
