Prusa I3 motors stop randomly while printing 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!

Use NC (normally closed) endstops against ground, with pullup resistors. Try to lead your endstop wires away from your motor wires. Twist the wires in pairs.]]> Inhumierer General Mendel Topics Mon, 23 Jan 2017 14:05:47 -0500 https://reprap.org/forum/read.php?151,741512,741512#msg-741512 Prusa I3 motors stop randomly while printing https://reprap.org/forum/read.php?151,741512,741512#msg-741512
