      FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.0beta10 ELECTRONICS: Duet Ethernet 1.02 or later FIRMWARE_DATE: 2019-09-12b1
      

      disconnect all three thermistors, enter

      M308 S0 P"bedtemp" Y"thermistor" T100000 B3950
      M308 S1 P"e0temp"  Y"thermistor" T100000 B3950 
      M308 S2 P"e2temp"  Y"thermistor" T100000 B3950
      

      show error on all three (M105 show -273.1 as expected)

      attach thermistor on bed - show ok for bed, -273 for e0, e1 (expected)

      detach th from bed, attach one to e0, one to e1, e0 show ok 26C, bed and e1 show -273 (not expected for e1)

      disconnect e0, e0 shows 26, e1 show -273, bed show -273 ?!?!?!?

      further testing, e0temp pin name is reading from the left connector ( E1 thermistor2 according to image of the pinout) weird ..

      now it gets weirder

      thermistor attached to e0temp and e1temp

      M308 S1 P"e0temp"  Y"thermistor" T100000 B3950 
      M308 S2 P"e1temp"  Y"thermistor" T100000 B3950
      M105
      T0:26.5 /0.0 T1:-273.1 /0.0 B:-273.1 /0.0
      

      ok, T1 is not reading but... check this:

      M308 S2 P"e2temp" Y"thermistor" T100000 B3950
      M105
      T0:92.0 /0.0 T1:-273.1 /0.0 B:-273.1 /0.0
      

      I set S2 to e2temp and now S1 jumps to 92C
      if I return S2 to e1temp, S1 returns to 26C:

      M308 S2 P"e1temp" Y"thermistor" T100000 B3950
      M105
      T0:26.4 /0.0 T1:-273.1 /0.0 B:-273.1 /0.0

        looks like I found the problem ... the

        M950 H1 C"e0heat" T1
        M950 H2 C"e1heat" T2 
        

        both were H1 but I still think this looks like a bug... it's stated in documentation that for 3.x firmware sensors and heaters are separate and this does not look that separate 😄 ... anyhow, yellow duck solved the problem 🙂
