This small desktop machine is built inside a 300mm cube of 20mm extrusion. Work area is 14cm by 14cm. I used 400 step nema17 motors all around.

The method used for tool position setting is a matter of personal choice but this is what I do.

A simple Embroidery machine using an XY belt and pinion drive to drive a hoop under a standard sewing machine. Needle timing, machine power and stepper control are all provided by a PIC processor. A tablet provides the higher level formatting required for communicating with the PIC chip.

A simple low cost rotomolder.

Designed from the ground up as a low cost, highly scalable delta printer. This printer has been built as small as carry on luggage size, up to an 18in wide print surface and is capable of larger. Approximate cost is low to mid $500 range start to finish, including electronics for a basic model.

In this, the final part, I would like to introduce Machine Vision and show how it can be used, not only for tool position setting but also for resolving the triangle to calculate the G68 (local system rotated) for jobs which are not squarely placed on the work table.
