My Makerbot replicator 2 stops and restarts automatically. I lose the print and the extruder head does not move from the position. (obviously). We have checked wiring a few times. Have not seen any issues so far. Maybe I am missing something. We have recently changed the ceramic tapes, fans etc. just recently.
It happens once in a while. But once it starts, it continuous, and it doesnt stop unless we shut it down for a few hours. or sometimes even days.
Any ideas what the issue could be. Or are more details required.
