General Mach Discussion / Manual Motor tuning

Hey guys.
I finally mounted the z axis stepper on my Mill/Drill.
As it's a temp solution because I eventually will use a servo I just mounted it on
the side of the head with a belt going to the Micro feed knob on the mill.
Heres the issue.
Its a 140 OZ stepper as hardly any tourque is needed to turn that wheel.
its a 200 step per rev motor.
I tried to auto calibrate it like I did with my X&Y servo's but that dont float !!!
I set it to move 2 inches .. it moved like a 1/8 Inch so Mach set it to 10,000 steps per !!! LOL
That little puppy doesnt have a chance !!!
How can I calibrate a stepper to move an Inch when I want it to move an inch
Is the problem that Im using the micro feed spindle adjustment ??
The step down ratio must be huge . When I jog up and down its pretty dang slow.
I can deal with Slow I just want it to be acurate as far as movement measure.
Any idea's ??
