Thermistor 3.4 Beta2
-
I'm using a duet2 with 3.4.0beta2 firmware and when disconnecting an E3D thermistor the temperature reads -273 and does not throw any fault. Rolled back to 3.3 and when unplugging the thermistor it still reads -273 and but throws an open circuit fault.
Is the later the expected behavior. On RFF2.X the temp just went high to 2000 on an open circuit.

@that-guy-e open circuit is -273. a short is 2000

@jay_s_uk I don't think I was getting an open connection message.
Is the -273 new for rff3.x? Could've swear open connection was 2000 on rff2.x?

@that-guy-e open circuit for a thermistor has always been -273C AFAIR, although I can't be certain that's true for every RRF version. Open circuit for a PT1000 is 2000C. However, with a -273C reading you should still get a heater fault if a heater uses that sensor and you try to heat it.
