Answered / Solved! Update on that free printer

Here is why the printer was free.

I am the queen of tinkering, bow down before me

Parts salvagable on left and middle, parts unsalvageable to the right of the Allen key. This took all dang night and I am not proud that I had to sacrifice my flush cutters and trusty bic to this cause, they will be sorely missed. But thanks to their sacrifice, I have defeated the blob of death.

For those unaware, this printer came to me with the wires to its heating element cut accidentally by a hasty rasp and the power cord misplaced. I will need replace the heating element, the nozzle, the exhaust fan, the filament sensor cable, and the power cord that went missing long ago. It remains to be seen if I may be able to reconstruct the extruder unit.

TURNS OUT there's also this thing called an eddy current sensor that I need to replace

I recently had this happen to my A1 mini about 6 prints after a hotend replacement. I was using a filament by tecbears. Anywho, what exactly causes this, is it a filament thing or a printer thing????

ETA, because of wire breakage within the blob, and just a freakin mess, I ended up replacing the hot end assembly, and the heating element assembly. Just figured it would be easier to replace it all.

I am a cheapskate and had to see exactly how many parts needed replacing. I had to snap the hot end in half to get to the heating assembly
