What did you do mechanically to set up 1 step per 0.001 mm?
And I want to move at a max table speed of 12000mm/min. So that is

200kHz has a period of 5 uSec. (1/200,000) So there's no reason why you
cannot use a 1uS pulse but the space would then be 4uS. I'd suggest making the
pulse 2uS and the space 3uS.
