I am running EMC and have no problem getting 180 ipm with Gecko step and
direction servos. Setup as follows:
5 tpi screws
2:1 reduction
for 10 motors turns per inch
250 line encoders at 4X = 1000 steps per motor turn

This works out to 10,000 steps per inch times 180 ipm = 1,800,000 steps per
minute
divided by 60 = 30,000 steps per second.

If I was limited to 4096 steps per second I would have a max feed of 24 ipm.
At 8000 pulses per second I would only get 48 ipm. Pretty whimpy.

There is a period parameter in EMC that can be adjusted which will alter the
rate the interrupts occur at.
