Your calculations for your motor steps per unit are way out.

Modern drives use microsteps (my Geckos have 10 - yours may be different - they may be switchable - if they are try 1/8th as a compromise). Modern motors are normally 1.8 degree motors so in themselves require 200 steps per rotation. So combined with the drivers they require 2000 steps per rotation - NOT 32.

If you then attach this motor to a leadscrew on a lathe or mill, the leadscrew will require a number of turns to move one inch - mine is ten, so I needs 20,000 steps. I also have a gear down system so my actual steps per unit is 60,000.

Set your steps per unit at what you calculate it will be on the mill you are building - or pretend - about 20,000 which isn't far off. The fill in your speed per axis at about 10 ins per minute, and set your acceleration at one.

See what the results are then.
