Make sure that your extruder gears are clear of any leftover plastic.

Please see Checking/re-aligning the Bondtech gear (MK3S/MK2.5S) for more information regarding the MK2.5/S and MK3/S/+ or this article for the Original Prusa MINI/MINI+. Make sure the gear on the extruder motor shaft is tightened by its grub screw against the flat part of the motor axis. Both of them must be aligned with the opening above and with the PTFE tube below so that they can properly feed the filament into the hotend. Drive gears alignmentДouble-check the alignment of both extruder gears. Please see Idler screw tension for how it should be on your printer. Their tension must be accurate (neither too tight nor too loose). Try to loosen (or tighten) the extruder idler screw(s) (with the spring). If the extruder idler screws are overtightened, the gears will not push the filament properly. Make sure that your extruder idler is properly tightened. Make sure you have it set just right, as instructed in First Layer Calibration (i3) and First Layer Calibration (MINI/MINI+). Having the first layer calibration set too close can eventually cause a clogged hotend. You can check our Extensive Material table to confirm your settings.

It is important to make sure the temperature is corrected for the filament being printed. Try to increase the hotend temperature (Filament settings -> Filament -> Temperature вЊ) by 5 - 15 вЊ. Also, see if the 3D model is not corrupted or incomplete. Slice the model again using the latest version of PrusaSlicer and its filament presets. If the filament has been ground through and can not be unloaded from the LCD menu, follow this guide to manually remove it.
