During setup with my Duet printer, I'm getting a "A heater fault has occurred" error when trying to heat.
Your thermistor resistance/temperature values in the printer's firmware likely needs to be updated. Go to the RepRapFirmware Configuration Tool and follow the prompts until you get to "Heater configuration". Select the EO or E1 sensor channel, depending on your printer thermistor configuration. Then, click in either R25, β, or C, and select "Slice Engineering High Temperature Thermistor" under "Sensor Channel". Continue with the rest of the configuration and click "Finish" on the last page of the Configurator.
If you are updating your Duet printer, you will need to change your T, β, and C values in the M305/M308 line of your current configuration file with the values from the RepRap configurator.
For example, if the M308 line in your printer's configuration file looks like this:
M308 S1 P"temp1" Y"thermistor" A"e0_heat" T100000 B4725 C7.06e-8
You would change the T100000 to T500000, B4725 to B4723 , and C7.06e-8 to C1.196220e-7 for our 450C thermistor
The final M308 line would look like this:
M308 S1 P"temp1" Y"thermistor" A"e0_heat" T500000 B4723 C1.196220e-7
