Hello Everybody. I converted a CubePro Duo to Klipper using a raspbery Pi and BigTreetech Tango. I did some prints with original hotends and dual extruders. It worked fine then gutted it and put in a 2 in 1 out extruder with two steppers. Switching between the stepper motors to push filament through the hotend using the klipper interface works. Well. I can get both extruders to extrude and retract. When I slice a multimaterial file it starts printing with first extruder until it needs to switch colour. When switching, I see it retracts and goes to the purge bin. At that point it stops and throws the error: “The value ‘extra_extruder’ is not valid for EXTRUDER” I’ve gone over every setting I know about but no joy so far. Can somebody shed light on this for me?

and I sorted it out by re-reading the page here a few times and playing with instructions from there. I got it going. On to the next step.

Somebody can mark this as solved.
