Thanks, I'll look into that. Meanwhile, I can set some hotkeys to jog and look at the 5th axis on the diagnostic display which is good enough for now. I was just hoping there was a way to see it on the run display.
Perhaps you can help me with something else. I'm new at this and have run into a bit of a snag. In order to initialize the machine, I can see how you can use G28 or Reference to set Mach3 to home. However, if the home position has been lost, then it is required that you disengage the physical drives after moving manually to home, and then use G28, etc. Is there any way you can set values in the machine coordinate DRO's? As far as I can see, you can't zero the DRO's or enter values from the keyboard.
