It would have been OK if I had noted down the X Y Z numbers when I paused the print ... at least I would have stood a chance of resuming where it left off.
I know what you mean not there .... my other 3D printer decided to lose its nozzle ...... hot filament went everywhere ....
I stripped it all down ... heated up the parts and peeled what I could off ... then used the non acetone nail polish remover to soften up the PLA I couldn't get to.
Cleaned threads and refitted. Lasted about 10 minutes ... same again.
Bought new head parts ... fitted ... BINGO ... jobs a good'un.
But I certainly do not want to repeat the clean up !!
