What is the problem?
I have updated my good old Mendel90 to dual extruders and Klipper Firmware (RUMBA Board) and it runs fine. Octopi is the latest release (2 weeks back). I have defined the 2nd extruder in Octoprint and the temp page mshows both. But the next page, where I would extrude/retract only shows one extruder and tool change doesn't work ("Unknown command:"T1"").
Recv: // Unknown command:"T1"
Recv: // Unknown command:"T0"
Klipper doc says it knows the Tx command, then why doesn't this work?
Hello @ralfsteck !
Have you setup your printer.cfg correct?
You may go to the klipper discourse for further help.
at least Klipper doesn't moan about printer.cfg and the printer runs when I control the 2nd extruder via GCode commands in the terminal.
This is a response of the Klipper firmware that the command is not known.
BTW: Have you setup OctoPrint for two extruders?
I don't want to be rude, but my question is literally why the "command is not known" when the Klipper doc says it knows that command. And yes, as stated in my 1st post I defined the 2nd extruder in Octoprint.
I was hoping there is someone who has a similar dual extruder configuration.
I have a dual extruder (IDEX) on my T-Rex 3 (See my post on the Klipper discourse)
Can you post your printer.cfg so that I may compare it to mine?

You are missing the gcode macros for T0/T1:
# Activate the primary extruder
# Activate the secondary extruder
Mine are quite specific for an IDEX printer with some additional moving.
That sounds right, I was wondering where the connection between extruders and Tx happens...
Edit. Thanks, that did the trick...
I am having a similar problem, Where do I insert this code in Octoprint?
Activate the primary extruder
Activate the secondary extruder
Hello @LunarBurns !
You insert it in your printer.cfg of Klipper
