Linear motion design
hi,
i'm planning make electronic chess board scratch using arduino. i've completed chess engine a.i. use (something around 2400-2500 human elo rating); can see code here: https://github.com/crybot/napoleon
the idea move pieces electromagnet positioned under board , moved 2 stepper motors.
to translate rotary motion of motors i've thought of 2 design: first based on sort of rack , pinion (but toothed string stationary , rotational movement of gear should move toward it); second option use lead screws or ball screws let electromagnet move around xy plane.
i'm tempted choose first option ease of implementation , cost, i'm not sure if high precision required task still there @ high speeds of motors (it nice if reach every square of board other square in less 2-3 seconds), better use lead screws control motion of electromagnet?
the idea make that: https://www.youtube.com/watch?v=xcp4m08iwna
thank time.

belts or rack , pinion work fine. there millions of 3d printers use belts (like makerbot) drive extruder head , capable of reliable, sub-millimeter accuracy.
