      Hi Everyone,

      I'm sure you have seen this popup on this forum before, but I'm having an issue getting my slice engineering RTD RT1000 high temp thermistor to read correctly on my Duet 3 6HC. I setup the GCODE using the Reprap Configuration Tool as the slice instructions tell you to.

      I'm currently running a Duet 3 MB 6HC + Duet 3 EB 3HC (This is a ratrig IDEX V-cast printer)
      Please keep in mind I'm still pretty new at this and kind of went and dove right in.

      The temps with the Slice instructions are in the high 200C without the heaters turned on.

      Here is my config for the thermistor's/ Hotends

      Any help would be much appreciated, I'm hoping to get this printer up and running soon so I can start tuning.

      Thank you,

        If they are PT1000 sensors, then surely the M308 should just have pt1000 as the type?

        eg.

        M308 S1 P"temp1" Y"pt1000" A"Extruder"
        

        The lines you have at present define them as thermistors with cold resistance of half a megohm!

          It appears defining them as PT1000 have made the temps look a lot more normal.

          As for the half a megohm that was following the slice instructions. This is a high Temp thermistor, does this not seem right?

          Sorry I went a little over my head with this printer and wanted to make something i can fully tinker with.

            Good to see it's working OK now.

            A PT1000 is a calibrated platinum resistor which should have a resistance of 1000 Ohms at 0'C and still under 3000 Ohms at 500'C

            The 500,000 Ohms stood out as for some different type of sensor.
