I disassembled the extruder until all I had was stepper motor and the extruder body part mounted to it. It would help to remove the stepper motor but one of the mounting bolts sits right behind the filament tensioner! I can see no other way than drilling a hole through the tensioner to get access to the nut.
To get the tensioner bolt off I think the only solution is cutting it in half somehow. There is maybe just enough room between the tensioner and extruder body to fit a hacksaw blade. I just wonder if there is room inside the extruder body part to move the blade back and forth enough to actually cut the bolt.
If and when I manage to get the bolt off i think I'll have to repair the tensioning system somehow. Has anyone done any upgrades to it?
Any ideas would be highly appreciated!
