Does anyone know why this might be happening. I turned up the pots to 70%. Should I turn down the pots or adjust the alustruder or is there something completely different? The printer is a Printrbot metal.
I get shredded plastic when I have too many retractions in too short a time. Making the retraction too big also hurts. Finally when an extruder starts getting dirty causing jamming the stepper motor on that gear can reset forcing the teeth of the gear to chop through the same spot on the filament again do this a few times and a hole is worn in the filament ending extrusion.
Trying to force material that doesn’t want to go is what gets it to shred. Do you know your temps are good? Too hot or too cold and you risk jams. Too cold can only melt plastic so quickly, too hot and it might be burning up in the barrel. Or you might just have debris. Too much idler lever pressure and it might cause problems by the idler bearing flattening the filament.
yeah,i think you should clean up your nozzles and wire feeder supplies cone crumbs ,and it will be better
What are your settings? Speeds? Retraction? Temps? Something ain’t right.

So it’s my little brothers printer and he is using the Cura profile for the printer so travel is 60 print is 40 bottom layer is 20 and were extruding at 208 (which seems to work on my printrbot). Hope this info helps. I’ll try loosening the extruder.
I tended to get shred when my idler was too loose, but YMMV.
Three cold pulls with 618 nylon cleared the crud from my printers’ nozzle.
