RRF 3.01 RC6: TMC temp reading not working
-
Using RRF 3.01 RC6 (DWC 2.1.0, DuetWifiServer 1.23) on Duet2 Wifi I‘m not able to monitor the temperature of the TMC2660 drivers. Reading in DWC is always 0.0.
Config:
M308 S10 Y"mcu-temp" A"MCU" ; MCU temp works
M308 S11 Y"drivers" A"TMC" ;TMC temp doesn’t workWhats wrong here?

@GerdJ this is expected behaviour, as the TMC drivers don’t report actual temperatures, just flags for different states. While it doesn’t specifically say this in M308, see the entry for M305: https://duet3d.dozuki.com/Wiki/Gcode#Section_M305_Set_temperature_sensor_parameters
Channel 1001 represents the temperature warning and overheat flags on the TMC2660, TMC2224 or other smart drivers on the Duet main board. It reads 0C when there is no warning, 100C if any driver reports over-temperature warning , and 150C if any driver reports over temperature shutdown.
