Hi John,
I don't have any PCBs done as it is too expenssive... I was hoping to get a bit more interrest from members of this forum so we could group a PCB order to get the price down. But it did not happen so....
I can provide you a schematic and an image to program in the PIC microcontroller.

For the 4th axis, At the moment all buttons are used X+, X-, Y+, Y-, Z+, Z-, Sart and Stop.
But I CNC the top cover of the enclosure myself. If could be machine differently to add a 4th axis... Or even use a different enclosure bigger to do more ???
The PIC micro controller I used has plenty of I/O spare so....

Have you got a PIC programmer ?
