Looking for help with a Zenbot machine

Ermmm. . with all the troubles you had with these allegro chips I'm surprised at you saying that Hank. . Lol

Lol, well during the time I owned it..I never has all three ICs blow at once (they blew in staggered formation - to cause the most inconvenience!). To be fair 50% of the IC blow outs were my fault (ignorance/sloppiness) ....but that particular board is not a great design because the IC holder contacts get dirty over time, leading to poor pin contact (result = no workeee as you'd want)

That said one of the beauty's of this board is the important bits that blow are easy replaced.

which is a blessing but also a curse because like I say, I don't think the IC holders are up to it. So it's sort of circular problem ...i.e. the board doesn't work well because of the design, but you can change the ICs out easily because of the board design!

I still think (assuming 24V is plugged in to the board & a 25w ribbon connecting the control box back to the PC is in place) that if *none* of the axises are working, then it's likely to be a Mach 3 config problem (cos from recollection it wasn't that simple to configure the mechatronics board as a n00b in MAch 3)
