If the filament is stuck in the UP mini or if it is broken inside the extruder

First of all, remove the nozzle and select “Extrude”. If the filament can be extruded successfully, the nozzle should be jammed.

If the filament can not be extruded, it should be the issue of nozzle heating element. You can disassemble the extruder head and clean the nozzle heating element.

Use a pin to clean the nozzle provided the nozzle is hot, then extrude the filament and check.
Please do the steps above and judge which part was jammed.
