WHAT IS AN “MPG”?！

MPG stands for Manual Pulse Generator and is basically an electronic hand-wheel. It’s the silver dial on the front of the machine in the picture to the upper right. By selecting it’s function in Mach3, when the user rotates the MPG it moves the selected axis. It has 100 detents per revolution and each detent or hash line equals approximately .001″ of linear movement. It is an asset when referencing the cutter to the work and a neat way to jog the spindle around.
