The resolution of a machine is the smallest distance ONE step produces. That boils down to Steps per unit. You can't make a machine have more resolution that what the steps per unit are. Mach can take fractional steps per unit but it has to average them out of a distance by applying an added step here or there to get that close. To get higher resolution you either change the gearing between the motor and linear drive elements or you get a higher resolution motor (Servo with high line count encoder)
With no information on the motors, linear drive type or any gearing its just a general answer.
Dfox1787,
