Your drives main dip switches let you set the Motor Amps and Micro stepping. Motor amps is easy just select the nearist lowest setting to the motors Amp rating.

Micro stepping (MS) is dependant on how you want to run the motors. In general setting the MS to a higher setting gives smoother running motors and to a lesser degree some resolution gain. The trade off is it works the PC and parallel port harder has it needs more pulses to move the same distance has a lower setting. There is also a limit where it's no longer benifical going higher, this around 2000 pulses, but won't get into this now.

What you want or need to know is the relationship between the MS value, ballscrew Pitch and Mach's Step Per setting. . . . It's quite easy really when you get your head around it.!!

Mach Steps per is asking for the number of pulses(steps) to move 1 unit, so if mm's then 1mm.
To calculate this you need to know the Pitch of the Ballscrew, NOT diameter, Pitch is the amount it travels for 1 revolution. Along with the MS the drives are set too.
Then divide the MS by the Pitch. Ie: MS=1600/5mm pitch=320 Pulses(Steps) Per/mm.
If your machine is moving the wrong amount it will be these settings causing it.

The velocity and Acceleration are then adjusted based on your preferances on speed and what the machine is capable of. There are far to many factors which affect this and really nobody can give you any accurate settings for these only guide lines has it's mostly trial and error which is based heavily on the individual machine.
