So it was printing perfectly well for me and I went to print some simple shims the other day and all that came out was a clear film. If I manually feed the filament or command the filament feed to feed some filament it flows out just fine so I don't suspect a clogged nozzle. I honestly haven't had much time to try and troubleshoot this so I thought i would just ask here in case someone had experience with this. I saw that nozzle height can do something similar but I haven't adjusted anything since my last print. May still be the problem though. Thanks in advance for any help!
