Catastrophic print fail damaged thermistor?
Hi Everyone,
Yesterday I had my first fail in the first week using my new assembled Prusa Mk2s. It was an overnight print (silent mode, PETG filament).
When I checked in the morning, the bed was a complete mess. Filament all over the nozzle area, really horrible. I preheated the nozzle and scraped most of the filament out but it's still looking bad.
Anyway, I tried to print something again today after cleaning and now all prints are stopping at some point with the "Bed Thermal Runaway" error. Does anyone have experience with it? I found out that this is related to a fire protection mechanism. Should I just assume the overnight failed print damaged the thermistor or something else? Any thoughts?
PS: Noob here when it comes to 3d printer engineering so I really don't know what to do.
PS2: Before the fail, I had PETG successful prints before just using the PET preset, no changes at all (Slic3r)
PS3: The print had a lot of elements in the bed, maybe this was the mistake that caused the fail?
