I left the print over the weekend and I came back to spaghetti. It looks like something, caused the printer to push the print off its base like it was a poorly leveled bed?
I still have to watch the camera footage to see what failed, but I hope you guys get a chuckle out of the spaghetti monster like I did.
Congratulations that nothing caught fire and everything just burns down.

But does it fly?
It would at least once lol
Ender. Happened back in the days with a 3v2, the stepper drivers on the original mainboard overheat, causing it to 'miss' steps.
Replaced the MB with an improved version, tuned the vRef and never had any issues again.
You might look into tuning the vRef for your machine.
Thanks for the tip! I’ve been hesitant to start messing around to much but I think it should if it means it’s more reliable
Oh my, it honestly looks kinda cool
I thought so too! I cleaned it up a bit and glued the bottom back on. Its my pencil cup at work now
It looks like you missed some x and/or y steps, which made the printer lose its orientation and make a lot of spaghetti.
Possible causes usually involve warping, the nozzle catching the wrapped up piece, and then your printer missing some steps.
Have you completed a large print before?
I have! This printer actually finished a 3ft sailboat rudder before this print. I popped some pictures of it in as well
Do you think that could be be solved by adjusting the z offset?
If the print didn't come off the bed, I don't think adjusting z-offset will help. As prints get taller, if you're running into issues with warping the corners will start to curl up.
Your printer definitely missed some x or y steps. Whether that was due to your drivers getting too hot and just that, or the extruder running into the print. Have you ever seen your printer do this:

If you already have a camera on it, you're halfway there.
I’ve been looking at this for a while. The camera I have on it is a security camera that i put on my desk while it prints if I’m gone.
Do you think its worth pulling the trigger on a raspberry pie to get this set up?
I've been using a pi3 b+ with octopi and so far it's great even without obico, plus super easy to set up. I set up octopi to get my ender 3 away from high occupancy areas because the hot plastic VOCs were giving me paranoia :P I can recommend investing in a solid setup for any small computer used to drive 3d prints. My setup is a hack with no thermal management and a crap power supply and I've lost a couple of prints to unknown causes but I blame the raspberry pi (it's almost always reporting under voltage events in the octoprint UI).
Has anyone here run self-hosted obico? I'm not keen on the cloud version but if the failure detection works in self hosted mode I'm definitely going to give it a try.
If you do long prints, yes. You can set it to stop the print automatically, or alert you to take a look.
Would.
