So, I haven't touched my printer in almost a year - got everything set back up again, but can't for the life of me remember how to do much. Things worked fine before and nothing has even been moved since it was last used. Restarted the printer a few times and now doing a G28 gives the message "Homing failed - PRINTER HALTED - Please reset. Before that, this is what happened: Doing a G28 puts the printer in a different position each time. This is the output I get: Recv: X:22.00 Y:23.00 Z:-1.31 E:0.00 Count X:1760 Y:1840 Z:-1040 When trying to run a G29 J command it starts off fine, but when tries to move the head off the table, which makes a ton of grinding noises. I'm not sure if something is messed up in Marlin or a stored printer setting. I'm thinking it might be best to wipe and start fresh. Error in Octoprint: Changing monitoring state from "Operational" to "Error: Printer halted. kill() called!"

Decided to print a standard calibration cube I have saved in Octoprint and that printed perfectly, except it wasn't even close to being in the center like it always has been before.
