At 4000 steps/mm *133.33 mm/s (8000 mm/m) the step rate is ~533 KHz.
so your 700 ns step length and 700 ns step space are fine as these limit
the maximum step rate to ~714 Khz   = 1/(steplength+stepspace)

The drives maximum step rate in step/dir mode is 4M steps per second,
which means ~125 ns minimum step space and step length so you have plenty
of margin. The setup and hold times are relatively unimportant as long as they are
long enough (they do not affect performance)

Note that all this assumes differential (line driver) wiring not open collector.

Does the 6I25 finish configuration loading?  (no red LEDs except briefly at power up)

Is the 6I25 jumpered for 33 MHz PCI clock?
