Try these from my Longs motor DM542a's
Some might say these are too short but they work for me on a Mesa 7i76e. If in doubt, double them.
# these are in nanoseconds
DIRSETUP = 500
DIRHOLD = 500
STEPLEN = 1500
STEPSPACE = 1500Some might say these are too short but they work for me on a Mesa 7i76e. If in doubt, double them.

I think the dm860 are a bit slower. Couldn't find exactly the dm860a, but the manuals for dm860m and dm860 both say > 2.5 microseconds for steps and > 5 microseconds for direction.

the DM860 A verison is a clone of the 880 with low level fet
you shoudt start standard at
# these are in nanoseconds
DIRSETUP = 15000
DIRHOLD = 10000
STEPLEN = 5000
STEPSPACE = 5000
i got in the 880
DIRSETUP = 8000
DIRHOLD = 5000
STEPLEN = 3500
STEPSPACE = 3500
Running 12meter/min at 100Steps/mm

The manual for the dm880 says 5 microseconds for direction change and larger than 1.2 microseconds for step, so that was an odd advice.
