TurboCNC and Re: machine(software) setup for rotary table

In TurboCNC you need to select angular on the axis you are running.
I think if you left it in linear and did not change your steps you
get unexpected results.

Turbocnc- 4set-up -2axis - W and Q steps thru axis's
2=linear or angular.

my default is 0.0002187 on X,Y and Z so if you did not change this
you would have odd results. and if you used axis A which defaults in
angular, the default might be 1 degree per step.
as was stated, if you use a 200 step/rev stepper and TurboCNC thought
is was 1 degree per step, then you would only move 360 steps when
commanded to make one rev.

at 2,000 steps in microstepping mode, you would only move about a 6th
of the way around.

If I am not mistaken, TurboCNC allows you to select the starting
rate, the acceleration rate and the maximum rate.

This would mean different machines would move at a different maximum
speeds. I run at about 10,000 pulses/sec on my 486-100 as the maximum
reliable speed is reported to be just over 11,000. (oddly enough, my
AMD-800 also reports just over 11,000 as max reliable)

Of course, max speed is not typical machining speed.
