The calculator should get you going but its easy enough to work out yourself.
10 TPI screw would equal a metric pitch of 25.4/10 =2.54mm
So to calc it will depend on what stepping the dip switch on the drive is set to but we will say 8 for this calc
200 steps for motor, multiplied by 8 microsteps for drive =1,600 per motor rev, assuming no gearing between motors and screw the pulses needed to turn the scrw one rev would be the same. So one rev of the screw moves the axis 2.54mm and it takes 1,600 pulses to do that so 1,600/2.54 is 629.92125965 which is the amount of pulses (steps) required per unit (mm in this case)
