Presumably it is running in velocity mode?

Still wondering how I might make the spindle turn slowly and then stop on a
sensor signal. From the HAL file it's set up the same way as the XYZA axis
with respect to step_type and control-type.
I'd want to set the velocity to say 30 RPM (0.5 RPS) and during a revolution if

What about a custom draw bar with an Andy Pugh style air cylinder release?
Seems simpler to engineer the mechanism than do all this control. Just have a
drawbar that’s normally retracted with a flange. Engage the flange with a
mechanism on an air cylinder to release.
You probably don't need more than 1 bar on the lifting air cylinder, up or
down. No need to force it down.
So let it down, then if you can give the spindle a 1RPM burst to let the
nut slip over.
And have a switch on driver Z to know if it's down over the nut.
You could also stop the spindle and

Nope. As a friend said the other day when I asked if he'd found a lock on

Is there a way to tell the spindle to
Well, i think i will improve my pid to make it more accurate and then
continue with the tests.
About the range of the angular axis, if i use the index-enable pulse of the
mesa 5i20 encoder module (wich says that the position is reset to zero when
an index pulse has ocurred) for reset the counter
Well the thing that comes to my mind is to make something in hal and use the
index pulse to reset the C axis to zero everytime the pulse is activated. So
the axis count will go from 0 to 360 degree and then start all over again
from 0.
Well it's just an approach to what i'm trying to do, i
I haven't tried the ss-wrapped-rotary branch yet but I will shortly. It may
do what you want in keeping the numbers between 0 - 360. That is the
specific purpose for it.

Hello guys thanks for the attention,
I'm making tests with a telemecanique VFD that has the +/- 10 volt analog
input (as far as i know is a vectorial vfd but i don't know if it's the same
as a flux-vector), i tried both using as a spindle and as an axis, and
worked ok... i didn't tune quite well
Hello guys, i've already asked something similar in the forum but this is a

I read about the retrofit of the mazak that some of the guys made, and i'm
making tests with an AC motor with a vfd and an encoder..
So i was wondering if i can make the spindle turn and stop in a given angle?

It would be could if i can make the spindle turn degree by degree, but i
don't see a gcode to do that.
Some machines need to orient the spindle so that a tool changer can
