Hello - first time posting here.
one of my ender 3V3 Plus is behaving badly. I have long print jobs (~10 hours) - The 3V3 prints fine until this critical behavior kicks in randomly (feels increasingly often). The head suddenly travels up and down, sideways for about a second, typically ends up abuot 4 inches above where it should be, and starts to continue to push out filament from mid air.
I am out of ideas, it’s not the G-code issue as my other 3V3 prints from the same g-code perfectly evey time.
Asking creality printer Gurus for help.
many thanks!!
