Unable to print PLA (self.3dprinting)

submitted 1 year ago by Fabrik872 to c/3dprinting

Hello all,

I have had Prusa MINI for a few years already and I have printed PLA without an issue but recently I have printed only PETG for some time I got through multiple spools of PETG without any print in PLA. But after I tried to print PLA my extruder kept skipping and grinding filament and when I tried to feed filament by hand it went easy for a little bit but after that, it went very hard as if the filament was cold so I tried to bump up the temperature to 235C and it helped a little bit but on faster sections of print like the infill extruder is skipping again. I don't think I have unreasonable speeds i am using a standard Prusament PLA profile with Prusament PLA. I have also tried PLA+ from some different brand with the same result. Then I changed the nozzle from an E3D hardened steel nozzle with nano coating to brass (not new I have printed PETG on this one as well) still with the same result. PETG is printing fine. Is there something I can try, please? I am out of options.

The Ptfe tube is likely the answer, if you can replace I recommend trying to. Make sure it is seated correctly and properly clamped in place when you’re putting it back together.

Good luck!
