EMC w/ steppers&xylotex

MLI (momentary lapse of intelligence)on my part. I had two cables and
a gender changer in line from the computer to the drivers. Removed
one cable and re-wired the gender changer for the cross-over. Now it
is working correctly. One more question though: is there a way to
limit the max speed in the software? As it sits now I need to run
the "axis speed" at 1 and the "feed overide" at 15 so the motors do
not stall. Or is there a way to establish a ramp up to speed as it
seems the motors start out at full speed (not much of a ramp if any).
I am not looking for a super fast production machine "YET".
Thanks Again

Ken
