Hi, here's my problem:
I've got a prusa i3 and one day i was heating the extruder to clean it. Doing so the 2 wires of the heating cartridge, which got naked over doing that kind of stuff i guess, touched each other. They went red.
When i checked out my printer i found my hotend's thermistance died but also the heatbed doesn't heat anymore and the extruder stepper motor doesn't work.
I first thought it was the ramps that melted in the process so i changed it but nothing.
I'm struggling to understand what's going on.
I checked the stepper motor and its polulu and both work. The heatbed themistance seems to work as well. Anything else seems to be ok...
Do you have guess?
Thanks anyway.
