http://home.nc.rr.com/alan69/CNC/ This is some of the code, and an intermediate Eagle layout for my newer
driver board to show the driver sections. Note that if you stuff the bottom
left 4 FETs you can run 4 phase unipolar, 4 phase bi with the left 8, and all 10
and cut the drive track join to power will let you do 5 phase motors. It's
basically the one I'm using but reworked to optionally support 5 phase motors as
well.
I'm going to try and polish it off soon and then put up construction details
for it and the mechanics. It's not exactly heavy duty mechanics but good enough
for drilling etc. Same CNC I posted a pic or two of quite a while back.
