Short version - filament is breaking 6 inches outside of the sensor when no one is in the room. Why?
I print on my new mini all day just getting use to new machine, no problem. Turn off, leaving filament inserted, come back next morning all is well. At 2 PM filament is broken about 6 inches outside of the filament sensor. There is also a break in the tube between the head and the servo. Never breaks while printing and I have done some > 8 hr prints. No pets, spool holder and mini have not moved. This spool is close to empty did not have the problem for the first 3/4 of the spool. Does not happen when printing. This has happened at > 3 times. In Oklahoma with 80 F room temp. Outside is 73 to 96 F > 65% humidity. The filament is leftover from my old MendalMax3 but was still vacuum sealed when opened. Any ideas?
