stepper with DIY type controller

how hard is it to make your own driver to run say a nema 17 size stepper that has a potentiometer to drive it ?

I recently used a power supply and microstepping driver, combined with arduino and thumbstick/joystick (which is basically potentiometer) to control two Nema 23's for both axis on my lathe. Its far from elegant but does work.
Its a temp soltuion whilst i source a pc/laptop with parallel port.
Code for arduino is relatively simple as is the wiring.
Is this the kind of thing your on about doing??
You may infact be able to just use an arduino and a "motor sheild" if its Nema 17's.

i would like to build something like that, it doesnt have to have all the bells and whistles but a basic move x trigger shutter move x again and repeat

This is something i have considered, any use ?

There is a shop to buy the bits and you just need a Arduino and a couple of stepper motor drivers.

thats exactly what im after !

thanks jon !

just wish it was in stock :-|
