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

Ho
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 de

Nope. As a friend said the other day when I asked if he'd found a lock on
his... "I use a big hammer on the supplied wrench to tighten or loosen it".

I'm running my AC Servo spindle motor as step/dir and can easily tell LCNC to

Well, i think i will improve my pid to make it more accurate and then

an index pulse has ocurred) for reset the counter t
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

worked ok... i didn't tune quite well t

Hello guys, i've already asked something similar in the forum but this is a
simpler..
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?
