I need a way to pass a signal from Mach to cubloc for the collet closer.  I think I need a user DRO.  I need to make a couple buttons in screen 4 and have them open and close the collet closer.  I looked throug the WIKI and did not see what number I should use.  Any suggestions? I know how to use the brain to send the signal to the cubloc (thanks everybody).  I just need to know what to put into the buttons.

Thanks

Vince
