Printer crashes when heating bed
I feel like there are deeper underlying problems, but long story short my printer will shut off whenever I tell the bed to heat up. My vcore 3.1 worked flawlessly until last week. I'll post the long version of the story below in case the context helps.
My printer was working perfectly and then one day it started jittering when making movements along the X axis, and only X axis. Imagine ringing but so intense you can feel the ridges, and it made a noise like it was digging into the plastic. I figured the linear rails needed some greasing up and decided to take it apart and apply grease to the rails. While I had it dissasembled I decided to install the new orbiter v2 extruder onto the hotend. Then when I went to turn on the printer moonraker had trouble connecting to klipper. It could connect from mainsail to moonraker, but not from moonraker to klipper. I figured I would reinstall ratOS and it kind of worked, but now whenever I heat the bed to PID calibrate the whole printer shuts down after 5 seconds. The fuse is intact and I can turn it back on by flicking the power switch, but I can never turn on the bed heater. Also at some point in this ordeal the parts cooling fan died. I can plug in a different fan and it works but the original fan will not work. I've replaced the raspberry pi and the power supply and still no luck. I also ordered a new control board but it seems to be stuck in USPS purgatory. I was certain it was a bad power supply issue but now I don't know, so any lead is appreciated.

Can you post your klippy.log file?
after observing the back of my printer when it happens I noticed it glowed on the back of the power switch. Maybe over time the heat loosened the connection. I ended up wiring the power cord straight to the power supply and now it does not restart when powering up. The fan issue was unrelated, it turns out I broke a solder connection in the shuffle.
