My Prusa I3 motors stop moving while printing for no apparent reason. The extruder continues to extrude at the same spot until there is a massive amount of filament that produce a jam. The printing time on the LCD pannel continues to raise.
I tried different files. I plugged the printing in 3 differents wall sockets.I turned off the heat bed (in case my printer needed more power).
Everyone who has this problem seems to solve this with a new USB cable but I always print with the SD card reader.
It always happen after quite some time (> 15 min) and mostly after an hour.
The motors don't seem to be hot.
Thank you for your help!
