M105 response incorrect - missing T0, T1 - just showing T:

  • Hi,

    DUET Ethernet
    FW 1.21
    DWC 1.21
    CR10S with Dual extruders

    When sending an M105, the response seems to miss out "T0: / T1:" from the response and just shows "T". This means that when I connect in my external terminal, or even monitor the current terminal, I can not get the T1 temperature to relay.
    OctoPrint is another example which expects a T0, T1 response.

    Here is what I send and receive in the DWC:
    4:56:24 PMM105
    T:170.2 /170.0 195.0 /195.0 B:60.0 /60.0

    Looking here:

    I can see that the response should have this information included so I am probably missing something...

    Here is my config.g:

    RRF is reporting the temperatures of both hot ends in that response. The first is 170.2C, the second is 195.0C.

    Sadly the reprap wiki page doesn't say what the response format should be, or give an example for dual hot end systems except for the particular case of Repetier firmware with the X0 parameter added. The Marlin documentation doesn't say either. So it appears that there is no documented standard to follow.

    I'll add it to my list to find out some time exactly what response Marlin actually sends.

  • That is amazing dc42. Thank you very much indeed!
    Absolutely loving this board and firmware + DWC. Simply groundbreaking. Thankyou 🙂

  • @dc42 @Foosel suggests the format should be:

    Recv: ok T:195.0 /195.0 T1:188.6 /190.0 B:60.0 /60.0
