I'm trying to convert from Mach3 to Mach4 on my 3 axis mill.
I have a CNC panel with buttons and keypad. I'd like to set focus to a DRO from a buttons on the panel. This is to enter values in to the DRO.
I had this working on Mach3 but cannot find how to set focus to a control in Lua.
Does anyone know how this can be done?

Thanks

Pete
