Hi Mike,

That was incredibly useful !
Thanks. 

Have you configured the outputs ? I'm going to assume that they use port #1 and pins 2-8.
I'm using a G101 so, I have some soldering to do before I can test things out.

I Have configured my outputs, They too use port 1 and go from pin 1 to 16 corresponding to outputs 1 through 16

Excellent!

One more question, if I may.
Would you know what is the G or M codes are to toggle the various outputs ?

I will answer the best that I can, I may be wrong so hopefully brian or someone with more know how can correct me, but basically to control the outputs for anything other than the built in Mach functions (Like the spindle and Coolant relays) you will need to create some vbasic code in either a macro or a screen button using a command like ActivateSignal(Output1) or DeActivateSignal(Output1) So You can create your own Mcodes or alter the standard Mcodes by editing the associated Macro files or creating an on-screen control to control you outputs or do both. Hope that Helped...

Mike

Hey Mike, thanks again mate!

You're post pointed me to the "Customization WIKI" which documents the VB commands and constants for Mach (you were 100% correct by the way).
Are you sure you're not a "covert" Mach/Grex support guy ?

Marc.

Nope, just struggling with this day in and day out for the past couple of weeks so it is all fresh in my head.. give it a few more weeks and I wont remember a thing!
