ok ill try it. thanks

when I noticed it, it was originally with just single prints, i haven't had any problem with multiple. and im using the cura slicer

I really need help, i'm a student and my high school manufacturing class just got two new ultimaker 2+ it was working great but then this last couple weeks its been acting up. 1. the first problem is that after a print when i got to print again the machine makes weird noise and the feeder tries extruding really fast which makes it over feed and then stop because it grinds the material. I updated the firmware and that didn't help the only way to fix it is by turning the machine off and on again 2. the second problem is that when I paused it keep extruding leaving a huge blob of filament. Please Help! i
