Need PCB to support 10+ motors+etc
March 09, 2013 09:34PM
Could someone find/design a pcb to support 10+ stepper motors(including microcontrollers and such), along with other essentials for 3d printing. (XYZ, RGBWB, Infill, mixer, maybe 1-2 more for expandability, heating element, temperature controls, end-stops, SD-card, usb)

Q&A's for questions that I KNOW people will ask:
What is this for? multicolor 3d printer
What is XYZ? X-axis, Y-axis, Z-axis motors
What is RGBWB? Red/Green/Blue/White/Black
Why do this? Why not!

The RepRapPro multi-colour uses two Melzi boards, acting as master and slave with a comms link. You could probably do the same with any two boards.

After I have done a RAMPS board for Due, I was thinking of doing a "Super-RAMPS" to make the most of the ARM processor. The board would be 66% larger and should be able to accommodate 10 stepper drivers plus everything else. Super-RAMPS could also be made compatible with AVR boards as well I think.

two of those boards together won't be enough (only 4 steppers on each board, and at $150 or so each!)

I would really prefer to use 1 etched board than 3 of these things and have all those extra endstops/temp controllers, How much of a redesign would it be?
