I've had my up box for about a week now, I've completed 2 smaller prints and one larger 18 hour print before I started to run into problems. I loaded up another 18 hour print and it started fine. About two hours into the print it began to air print and no more filament was passing through the nozzle. I cancelled the print and cleaned out the extruder and nozzle. Ive also cleaned the gear with some acetone and a metal bristled brush.I set up the print again and it begun like before, but soon was back to air printing. If i pause the print job I can extrude the filament perfectly. Im really confused as to why it can extrude without hassle but doesnt complete the print. Am I doing something wrong or missing a step in the printing process?.
I didn't find the right solution from the Internet.
