Here's a screen set which I am using at my shop floor. It has Xbox 360 hand held controller support. I use this controller with an excellent plugin programmed by Lee Davis. The macros used with these screens are included in compressed file. The config screen for Xbox 360 is also included. I use the back and start buttons for activating the macros. The back button loads the Xbox screen on which X0, X/2, Y0, Y/2 and Z0 are selectable with the back button on Xbox. The Start button executes X0, X/2 .... commands which zeroes and halves the X axis. Similar functions for Y and Z axes. Basic idea is that I can locate and center a job on the machine bed without the need to reach out to the keyboard on the control panel. Very useful for large machines.
For installation, uncompress the files in Mach3 folder. The digital-7.ttf font file goes into the windows/fonts folder and in the Function Cfg's/Fonts menu in Mach3 select digital-7 as the font for DRO's to get the desired effect. Screenshots at
