Prusa MK3 thermal errors after firmware update
I've got what I believe is a Prusa MK3 (possibly MK3s?) that i bought secondhand a few years ago. It came with an upgraded Bondtech extruder and Revo 6 hot end and always worked great for me. I was out of the hobby for quite some time due to moving, work, and other issues. This week I decided to get back into it and set my printer up. passed self test prior to firmware update. I've updated the firmware using bondtech's website and now the printer keeps failing thermal calibration. Any time the hot end heats up it aborts aroundd 55-70 degrees and if i run a self test it fails due to "filament sensor wiring error". Im not completely sure if it is a mk3 or mk3s so i have tried both firmwares, including backdating to the 3.13.3 firmwares. any help sorting this out or where to start would be greatly appreciated.
