Experts,
I am a middle school teacher having students use Tinkercad for their design, printing to Ultimaker 2+. In recent times, some students at the end of their prints have the printer bury the nozzle in the print, squirt out filament into a small blob. When this happens, the feeder also chews up the filament and it needs to be cut and re-threaded. This issue seems to be happening more and more frequently on three of my six printers.
Things I have tried:
updating printer firmware
Re-exporting stl files from TinkerCad and re-slicing them
Using new, reformated SD cards
If anyone knows the answer to this question of what is causing this issue and how I can get it to stop, I would greatly appreciate this.
Looking forward to the expert community chiming in.
Cheers,
James
