Title: Adding external switches and relays
Post by: Plastic Jim on March 19, 2010, 11:57:05 AM

newbie.  I'm looking at getting a system with Mach 3 i currently have a benchman/light machine that uses  G25/G26 and M25/M26 to let me hook up external swiches and relays. how do i do that with Mach 3? Also if you have opinions on Tormach millers (thats what the boss is interested in) it's a production enviroment to machine plastic widgets, relatively easy to machine but we have to hold +/- .004 inch tolerances.

You're going to need a method of getting the inputs into Mach. I've seen a device called pokeys which may do it ? This is not for time critical i/o though.

You could add an extra parallel card to get five more inputs ?
