Ugh...
I just heated up the nozzle - it's PLA - heated it up to 210C - and I did a bunch of extrusions - and it was fine. Then, I went to reverse it - filament was backing out a little bit - but, suddenly stopped moving.
Now it won't go Forwards - am getting the obvious Clicking noises from the gears - and it won't back out either!
And - the print head looks complicated - I see no Obviously easy way to under this Jam!
This SUCKS!
