motor shield?

[nchapman]

have you planned motor shield for3D print or other?

Yes, already in our plan and using Geeetech stepper motor driver A4988.

Is the shield going to be a full on printing controller or just a motor controller?  If its a full controller how many inputs/outputs are there going to be for motors, extruders, heated beds, thermistors and so on.  What firmware would it run for 3d printing?
If you need any help/input on designing such a board just let me know.  I have an extensive background in 3d printing.  Can give you more specifics is needed.   My advise would be try to compete with the SmoothieBoard as that's the best consumer grade board currently available.
