Hello
I'm wanting to install five to six different 3d printer heads on my cnc each to have a different color, I want to use my gecko g540 A axis witch is no problem but i need to have a switch to switch between the five to six different steppers all controlled by axis A. So can anyone point me in the right direction. I should be able to figure out the Mach4 side of it but the actual switch is stumping me.

Thanks for your time
