I have not seen anyone tackle the tricky subject of the electronics. Here now is my attempt to do so.
step 1: parts You'll need: - an arduino (I chose duemilanova) (depends on the board you get) - 3 stepper motors (I chose NEMA 17s, though mine didn't come with molex on the end) ($15/ea) - 3 EasyDrivers from Sparkfun. ($15/ea) - some Cat5 ($2?) - a 5V power supply for the steppers ($5?) - a soldering iron - some electrical tape - an optional female plug is not would be a bad idea (>"); for (i = 0; i
