More playing about today, lashed some wires in for the two X axis stepper motors and got it moving, A is a slave off X
Settings as follows;
AM882 - microstep 8 giving 1600 steps/rev
Mach3 - steps per = 160 (using 10mm pitch ball screws), Velocity 10000 mm/min, Acceleration 3000 mm/sec.
Tried velocity up to 15000 but it stalled quite often, so the question is, how do these numbers sound ?
It's not clear how to set things like 'Kernel Speed' when using the Smooth Stepper, I set it to 35000 Hz anyway.
