The legend of the worst MK3 ever continues.

Well guys, I got a new Thermistor in the mail. Now I’m not getting the mintemp error when I do a bed level calibration.

But, now whenever I select to start a print or even just preheat, the instant I click the knob to start heating, the prusa crashes. The fans spin up, and it restarts.

What’s the deal now. Any ideas?
