I found this...
It comes with a cd that has the XP drivers ...14 bucks and I got my extra inputs ...It is a cheap quick solution if mach3 sees it... I want to get some
cnc router experience under my belt before I plunge into the next level upgrade ...(spindle, 4th axis)....still not sure how the touch plate gets wired
to the 2nd port, Would a dp25 male connector with two wires one on the ground and one on pin 2 - 9 do the trick?
