Hello,
I've been using my Mendel90 for some time now. I just loaded his third roll of filament, directly after that i started printing. First layers looked poor so is decided so restarted print, in the next attempt its even worse. I tried to reverse the filament but it wasnt going anywhere; tried to gently pull it with my hands with the motors off, no movement at all.
I took the extruder part of the X-carriage. Two things got my attention:
A. The extruder block is cracked around the bearings of the bolt
B. Filament melted before the extruder. Cant be moved forward or backward.
I tried reheating the extruder to 230 C, left it for a minute and then tried to pull out the filament. The filament instanly broke and now i'm stuck with a plastic filled extruder. I tried to push the fillament through the hot extruder but it's not moving at all.
Any suggestions on this problem? Otherwise; where can i get a new extruder / other extruder that fits (so i dont have to print another block when i cant print :| )
Tom
Edit: The 'where can i get a new extruder' question is because the reprap pages tell me that this particular extruder is not available anymore.
