For MPG#1 in Ports and Pins, set Counts/Unit to 4.
make sure in General Config -> Jog Increments in cycle mode, there is no empty slot. all fields should have some value, like 0.0001, 0.001, 0.01 etc.
tomorrow I will check mpg on a machine and let you know if I find any more step required to setup.

Rufi
