Hello,
I have something weird going on with my hotend. I tried printing a part yesterday and noticed, that the filament stopped extruding. I thought that there was a problem with the extruder but when as I took the Bowden Tube out of the hotend I saw a big chunk of PLA at the end of the tube that there was no possibility for it to go into the Teflon coupler (Filament softened in upper head) . As I took the whole hotend apart to clean it I saw the PLA stuck in the peek insulator.
I cleaned it and put it back together and the print worked for 10 minutes and then the whole problem appeared again...
Any suggestions?
With best regards,
Julian
