When I try to run the dual extrusion wizard it tells me i dont have a valid profile. There is none that I can see in the setup wizard for the robo r1 plus.
Isn't the R1+ only a single extruder machine? It looks like the S3D profile for that machine is also single extruder only. So if you're using that profile and that printer, then yes, it's probably setup for a single extruder by default. That's why you're getting that error.
Ive added a second extruder to it. I know you can setup cura for the dual on the robo r1 plus. But I much rather use the software i paid a small fortune for.
