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

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:
http://reprap.org/wiki/G-code#M105:_Get_Extruder_Temperature

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

Here is my config.g:

M83 ; ...but relative extruder moves
