As I understand, Steppers are limited to a very narrow peak of the
motor spectrum. Low speed, under "x" hp.

Larger motors are limited in power for the size of their coils and
are also limited in speed as time to charge and uncharge the coil
enters into the equasion.

Mariss had posted a common max speed for each stepper size, whereupon
the power drops off to some usless value.


To that end, 1,000 RPM on a stepper is 16.666 rev per second.
with a 10x microstepper, that puts out 2,000 steps per rev, one is
limited to 33,333 Hz.

I'm not sure if T-CNC or Mach are limited to a total of 45khz of all
three(4?) axis combined on a move, or if each of 3(4?) can move with
each getting 45khz ?

Funny, how when you can't get the machine to move that fast, you
don't care, or go another way.

I'm planning on changing my X from a leadscrew to either a belt or
rack. I imagine changing from 26,000 steps per inch to 4k will offer
some speed increase.

How-come-is-it that so many people have opnions of what V-4 is like
and it is not release yet ?
