Well, I always intended to print up spares for the extruder, but things kept getting in the way, ABL, tidying up the wiring etc. Well the inevitable happened, I had a cooling fan failure overnight and the heat warped and loosened the extruder block!

Luckily, with the help of a heat gun I managed to coax it back into some semblance of a workable piece, and was able to get everything calibrated OK.

Guess what I am printing now
