Octoprint disconnects when I issue a command

What is the problem?

I got octoprint about 2.5 weeks ago, a couple problems, fixed, and now when I booted it up and tested it by turning the fans on, boom, it says "Printer halted. kill() called!" So I came here

What did you already try to solve it?

Tried restarting both printer and octoprint, tried cycling the micro usb cord. I also tried running other commands, like leveling with the bed visualizer plugin I installed.

Have you tried running in safe mode?

Yes

Did running in safe mode solve the problem?

No

Additional information about your setup

I'm running Octoprint off of an HP desktop I booted to Ubuntu, I use Jyers BL/CR Touch firmware, and I'm viewing the UI from Firefox.

According to your log the issue is actually not issuing a fan command but rather issuing a home command (G28). Your printer then seems to try to execute that and finally gives up because something (which it doesn't further clarify) goes wrong spectacularly and so bad it decides to enter kill state.

Make sure the printer is powered on, that the axes can move freely, that the end stops aren't engaged but DO engage when the head hits them, and that in general your printer is mechanically sound. If that fails, look into the firmware. In general, try printing from your printer's SD card or something like this, make sure THAT works, then try adding OctoPrint to the mix. This is your printer saying something is terribly wrong, not OctoPrint.

Ok, I tried moving the nozzle up, nothing, tried auto homing, nothing. This was all done on the printers LCD, not sure what's wrong.

Nevermind, I plugged the printer into a direct outlet, fixed it.
