Was trying out some weird idea that I had to print and my Prusa i3 MK3S+ decided it had enough. It would loudly beep and then displayed Thermal Anomaly and paused the print. Prior to that it beeped a lot, but the temperature wasn't very far off, maybe 1C. After running self test and passing, and thermal management calibration, and PID calibration, all of which passed, I contacted Prusa for some help. While looking carefully at the hot end, I noticed that the thermistor wire was pinched or stuck. I did measure the thermistor resistance after it cooled down and it was around 110K ohms, which might be ok. Put everything back together and tried a small print from the SD card. (Normally I use Octoprint.) After only a few minutes, the printer beeped a lot and the printer did the Thermal Anomaly Pause again, pretty much the same behavior as when I tried to print a more complicated design from Octoprint. The pauses are not recoverable since they die within a minute or two of continuing. Certainly has been frustrating.
I've ordered a new thermistor, but I don't know if this will fix it. Hope it will though.
Anyone else run into this kind of thing? Seems weird it would show up more than a year after I built it.
