Not sure when i will get a chance since i am off for a week next week. I will get some photos tonight of the small box and write a small tutorial on setting up the BOB inputs as input triggers for buttons or similar. I do however want to find out if its possible to run the macro without this onscreen button since i would like to remove it and replace it with just the DRO for thickness of plate and then have some buttons for video centering and other bits and pieces. I will just assign it as the onscreen button that i use with my wireless keypad from within screen designer. I will setup the trigger with a hot key from within the ports and pins setup. After checking the mach site i realise that it is indeed alot simpler than what i need(For the time being). I realise i am over thinking things as usual. Thanks for the replies.Driving to work today i had a brain storm and currently installing mach 3 onto my laptop to check to see whether what i think is there, is there. P.S Can post photos of the setup if anyone would like to see them. Where can i setup the SetTriggerMacro for OEM Code 301? How can i use an input to run the Z Zero Routine? What i found online just didn't seem to make sense. Problem is after spending ages online last night and trying to sort out how to set it all up i ran outta ideas. I have a custom Macro (M999) setup with the z zero routine in the macro spot.

I Have the OEM Trigger Setup on the right pin and have setup the Trigger to run OEM Code 301 which should run a thing called SetTriggerMacro. It was easy setting up the OEM triggers for the EStop and Start/resume and Feedhold, but the last button for the z zero routine is troubling me. But in making life easier on the cnc it gets harder for a while while setting it up. Very simple to build and going to be a huge help(especially with tool changes, not having to walk back to the computer to press continue) and saves using the wireless keypad and keygrabber. It has 4 switches on the front (Estop/Feedhold/Resume/Z Zero), it also has a jack, to plug the probe into, so i can use it as either the z zero plate or probe.

This was for the old machine but is a test run for the bigger machine. I spent last night making up a small box with switches to use as an external e-stop and resume button and z zero etc. Was hoping someone might be able to help me out.
