Ender3 V3 + Stops before 1st layer starts

My printer was working just fine. Today I tried to print twice, once with the preloaded camera mount and once with my own print.
It homes, checks bed level and everything just like normal, but after it makes the purge line on the left, and begins to lay down the 1st layer, it stops for some unknown reason, no error code given other than unexpected error.

The ONLY thing that is different today is I plugged in the Nebula camera that I just got.
Any ideas?

Hello @Todd_R

I had a similar issue with my Ender 3KE. If the purge line is printing OK then check that the filament running freely. Make sure that your nozzle is clean and there is no blockage as even a slight blockage could cause the print to stop. Check that the extruder is working and that the filament is being pulled through. Check that the connector to the filament sensor hasn’t come loose.

Hope this helps :+1:

Just to be clear; the print head and everything stops, not just the fillament.
Is that the problem you had also?

If you unplug the camera and try does it work ok…?

Actually,
I ran the self test again, and unplugged the camera.
It started printing, then I connected the camera again and it’s still going.
Seems like the cause? Maybe?
I’ll need to keep messing with it.

Could there be a bug in the camera software? I updated it before I used it.
