Delta forum for 3d printers...

The usual software is I think Marlin running on one of the 3d printer boards based on an Arduino (Melzi / Ramps etc). That's probably the cheapest way to get it going because they're commodity items now (a UK sourced Melzi which includes the stepper drivers is less than £50 and there are cheaper alternatives). They read fairly standard g-code with some extensions and some restrictions so shouldn't be difficult to control.

I've heard complaints that the arduino is a bit slow for a delta because the position calculations are more complex than a linear xyz design but there seem to be plenty of people using them.
