Well, I just did some tests with a Gecko 201A with 49 V power supply and
some
NEMA 34 motors. I was running them at 48000 steps/second (the 201A is a x10
microstep drive) so it was running the motor at an equivalent speed of
4800 steps/sec
or 1440 RPM. On the 16 TPI threads of one of the common mini-mills,
that works
out to 90 IPM! But, perhaps you are not using NEMA 34 size motors.
