Hello, I’ve encountered such a problem. After installing max31865 from btt on a chc pro with pt1000, a Thermocouple reader fault appears in the following scenario:
Only heating the extruder - everything is ok
Heating of the extruder and heating table - everything is ok
Heating of the heating table - after a couple of seconds, the error “Thermocouple reader fault” appears
From the klipper log, I see that there is a max31865 overvoltage or undervoltage message. The power supply is spare, the sensor is connected and configured correctly (the toggle switches are set to connect pt1000 via 2 wires). I tried to connect it to both 3.3 and 5 volts, there is still an error in this scenario.
I can start printing by first heating the extruder then the table, so I think that the problem is with the software part.
