hello guys, i am trying to print a simple model with cura default settings (16 hours print). using in core 1 ultimaker genuine tough pla green and in core 2 ultimaker genuine pva support material.
after 4 hours i got fillament empty error, both of them were full so i observed the problem is in core 2 the pva one, so i just pulled it out and in and clicked resume.
since then every 10 minutes the print stops due the fillament empty error (the pva one). i replaced it few times, cleaned the core head and still it will give me this message again after 5-15 minutes in average.
also sometimes when it prints with the pva head i hear very weak "popping" like when you burn plastic or oil in the pan. i don't hear it when core 1 the tough pla head is printing.
some images of the print are attached. eventually i aborted it as it's not possible to work like that.
also when i woke up of course i had this error again so the printer was sitting for 6 hours not working and both motors were VERY hot. isnt there some safety option so the printer will turn off if it's not printing?
