Hello! I have a problem connecting a thermocouple. I use the Ruramps control board. The firmware is configured correctly and works for more than a year, but first I used thermistors. Then a thermocouple was connected to control an additional fan (it cooled the drivers). Everything Then he moved the thermocouple to the hot end and crashes began. During machine downtime, everything is fine. Heating (as well as calibration) of the extruder is successful. As soon as I give the print job - the printer goes to reset. It happens like this: The stages of heating the table and the extruder, the movement to the end switches and the start of printing, pass. When the job is completed, the print head goes through one line and the machine completes printing (lifting Z and turning it off). The temperature graph records its jump up. worked correctly. I tried a variety of G-code, including the one that was previously printed.The error appears in the same place - after the first line. There was a suspicion that a guiding voltage appeared in the thermocouple cable (from the extruder motor, for example), but the cable was shielded and, in plain time, tried to push the bar with the extruder, everything was normal. What could it be? If you need to attach a logs, I’ll put it out from chewing when I get to my computer.
