I can’t figure out how to connect a 3’rd motor, I have Smoothieboard 5x, and I also have Viki 2 Graphic LCD, which takes all the pins left!
Can Smoothieboard support 3 color mixing nozzle?
I have external microstepping driver, I only need 3 pins (enable, direction, and step), but I cannot figure out where to connect to (since the LCD takes most of the pins) ?
Thanks!
