How to drive 6 extruders

#1

I want to print 5 colors + clear=> 6 stepper + 3 axis.
Do somebody know a good board to do this?

I think the Duet with the expansion board can handle 9 steppers.

You can do this with almost any board with 5 stepper positions if you use the version of the Prusa stepper switcher that allows up to 8 steppers. I’m not sure I saw any of these actually being available, but it would be pretty straightforward to make based on their 4 stepper plans. You could even do it with 2 of the 4 stepper switchers. I am running 5 extruder steppers with a generic RAMPS board (4 from the switcher and one independent).
