Ender 3 V2 shows Error:Printer halted. kill() called!

What is the problem?

I pre-heat the printer and when I go to start a print it throws this error, kills the extruder and bed, and freezes the screen on the printer. This wasn't an issue for over 2 years and then I went to use it and it started happening.

What did you already try to solve it?

reinstalling The Ender 3 V2 pluggin
reseating usb and using other ports

Have you tried running in safe mode?


Did running in safe mode solve the problem?

Additional information about your setup

Ender 3 V2 running 1.0.2 with pi 3
OctoPrint 1.7.3
Python 3.7.3
OctoPi 0.18.0

I figured it out finally. My Y axis tensioner came all the way lose so it couldn't finish homing, causing the failure.
