Bed heating error out of the blue.
Hi all,
Following situation:
I was printing nicely, everything as usual, when I realized the print result was not what I wanted, so I cancelled the print job. Switched off the printer, fixed my model and started again a bit later. When I started the next print job (PLA), the hotend went way past 230 and likely more and I got a temp runaway error. The Heated bed was still at 24 degrees though, which already surprised me.
Now whatever I do the hotend heats up correctly, but the heated bed stays at room temp and eventually throws a Bed heating error.
The MK3S+ is at newest firmware.
I did not do any cable modifications or basically touch anythign at the printer beside the buttons between working and non-working state.
Did anyone else see this behaviour and knows a simple solution?
Otherwise I'll dig through https://help.prusa3d.com/article/preheat-error-heatbed_2161 and similar...
Thanks!

Well, false alarm, luckily.
After triple checking the power connection on the Einsy board I did actually see that ground for the heat bed had a mm wiggle room. Seems to have been enough to not give enough contact. Tightening the screw did the trick.
