I was succesfully running my printer for more than a year now, but during the last days a strange thing happens once every 2-3 hours.
during a print the whole printer shutsdown (motors, electronics, PSU)
in the repetier host I get a message, (hotend) thermistor reading error and then I have to reset the board and restart. In the temperature readings of the hotend I get a spike to 520C (which is an error as it goes instantly there), but I dont know if this is the cause of the shutdown or just a symptom.
When I reset my board the temperature reading work normaly and the printer also.
this strange behaviour happens from time to time and without any obvious provocation.
does anyone had similar problems in the past?
I use GEN7 electronics and repetier firmware
