Hi!
I tried searching the forum for someone who had experienced the same problems but found none
I was printing a large model, in total it would take about 6-7 hrs to complete, everything went smooth until somehow, the hot end stopped heating and the temperature dropped. The extruder kept on feeding filament, leading to a jam in the hot end because of the drop in temperature and the whole plastic tube popped off. Luckily I was around so I could pause the print. I tried setting the temperature to 195 degrees, but first it wouldn't respond, and the temperature would keep dropping, but after a while it responded and it would rise again. I tried resuming the print but the extruder would not work properly now, only turn back and forth instead of a steady feed of filament.
Now my questions:
Why would the hot end turn off mid print? Is it common for it to get overheated or something? Is there something I could do to prevent this from happening again?
And this problem with resuming prints when paused, why won't the extruder work properly after being paused? This has happened on several occasions before.
Keeping my fingers crossed that someone can help me out
