I have been using my A1
for about 5-6 months now and this problem startin 2 months ago. Randomly it eats away the end of my filament like shown in the picture and just stops extruding. It happens randomly. I can finish 60 hour prints without problem but then it just does this after 10 min. What could I do?
This will often happen when there is too much nozzle pressure which is normally cause by trying to print too fast, the nozzle temp being too low or a partial/full clog. The filament can’t be pushed through the nozzle at the rate that the printer is trying to and thus the extruder chews through the filament. Another problem could be the filament width being over the spec in that section.
Any chance you lost the bearing that supports the long side of the extruder shaft?
