Art - an important question may be, what's the 2nd highest EVEN TIMING
step speed? If the answer is 45,000 then there is a serious
granularity problem and the highest realistic step speeds may still be
hard to accelerate to without stalling the motor.

Would you be willing to talk a bit about how you do timing in Master5,
ie, what goes on in your custom timing driver?
