I have an interesting problem. I have Mach3 with a Galil DMC-1840 controller set up in Windows XP, with the Galil-ST plugin. This is connected to a Bridgeport knee mill with 3 axis servo motors. The servo motors are all connected and tuned. Mach 3 connects to the Galil controller and the motors all move in the correct direction and what seems to be the correct amount. My problem is that the DRO values for the X,Y,and Z axis do not change when the motors move. Even when not connected to the motors, when I input a move from either MDI or the MPG jog mode the DRO still reads zero. If I teach a program and run it, the simulator shows movement, but no DRO change. However if I click on the To Go button the DRO counts down the move and works as I think it should.
I have another system running Windows 2000 with a DMC-1750 controller and the DRO's read as they should. Did I miss something in set-up or what could be causing this?
