I recently bought a batch of push plastic brand pla and so far I’ve had a bit of grinding issues with the filament. It stops coming out in the middle of prints and I get ghost printing. Then when I remove the filament its been chewed on. Ive already gone through a lot of steps to solve the problem unsuccessfully:
- measure filament - it is at the top 3mm range but always below 3mm
- run unclogging procedures posted by lulzbot - I get constant extrusion no problem
- adjust extruder latch tension using the 3d printed jig
- lower printing speed
- experiment with temperature (used 195 to 210 temp range)
- lower retraction speed
Is there anything else I should be thinking about? The strange thing is I have another mini and that one isn’t having the same issue.
