I keep having an issue when removing filament from the Aerostruder.
After retracting the filament until the hob bolt doesn’t make contact, one of two things happen:
- There’s a long thin string of filament going down towards the nozzle. I try to manually pull the filament out but this string prevents it.
- There’s a thicker blob of filament that won’t go through the hole in the top guide.
I’ve tried using “Change Filament” from the LCD and manually moving the extruder. I’ve tried at full nozzle temp and at 122 degrees (so Change Filament still works).
What I end up doing is to get into the space between the hob bolt and the upper filament guide with a pair of flush cutters. Then I have to fish out the lower pieces with tweezers and compressed air.
What am I doing wrong?
