You don't have (or need) that pin with Hall sensors.

What he said. I'll certainly add my +1.  This list is in the top 5% of 
helpful lists I have been subbed to over the last 25 years, and I bow and 
give thanks in everyones direction.

FWIW, I got that spindle tachometer to display a few minutes ago, and I'll 
head for the shop & see how well its calibrated shortly.

Poor health is a bummer Peter, and I hope you get back to 110% quickly.

Cheers, Gene

Yes, I also want to thank the whole community of LinuxCNC developers, users
and even the occasional gadfly for this incredible project.  Not only is 
is a
business for me, but also something that I use in my own shop.  And, the
original EMC (I) from NIST was what got me into Linux.  I was always
a Unix hater, and still find a number of things that grate on me a bit, but
it gets the job done!  (And, it is a hacker's paradise!  I've always been
a hacker (in the good sense) at heart.)

So, merry Christmas and happy holidays to all, and a VERY good
new year!

Jon

Finally some success right on Christmas eve.
I enabled the index-mask and got the encoder offset = -103 counts.

I also discovered the epic fail in my config - I have not connected
bldc.n.init pin anywhere to actually tell bldc module to home the
motor. The problem is that I get an error message on startup. telling
that such a pin is not found. I connected it to halui.machine-is-on.

I did another test - I set cfg=n and then manipulated value and
frequency pins to find out, how fast can the drive spin the motor.
Based on encoder velocity, I got it up to 3000 RPM with frequency =
200 and value = 0.85.

I have a suspicion that I have an epic fail in my config, so I would
like to ask, if someone can help me out:
I decided that I should connect bldc.n.init pin somewhere so that
there finally is some signal that tells bldc module to actually home
the motor.
I have bldc cfg=qhi and LinuxCNC on startup complains that there is no
such pin as bldc.0.init. In HalShow I also do not see such a pin, but
I do see initvalue pin (which, according to manual, determines bldc
value, when homing the motor).

Next thing is that this page is confusing me:
http://linuxcnc.org/docs/html/man/man9/bldc.9.html

I do not understand, where to connect bldc.n.index-enable.
There is this sentence in bldc man page:
When the init pin goes high the motor will rotate (in a direction
determined by the rev pin) until the encoder indicates an index-latch
(the servo thread runs too slowly to rely on detecting an encoder
index directly).

While bldc.n.index-enable description tells to connect it to encoder
index-enable pin. Another point of confusion is that I do not see
encoder.nn.index-latch pin in HalShow, there is latch-enable pin. Is
it the same?

Peter and everyone,
I would like to second this by saying my family and I wish you guys a
Merry Christmas and a Happy and prosperous New Year to all of my LinuxCNC
friends here.  I am very new to this corner of the net and I am quite sure
I will be leaning heavily on all of you for assistance and ideas for my
Cincinatti Arrow 500 retrofit which is already underway in the coming
moths.  I have only been reading for a short while and I can see right away
that many of you are QUITE knowledgeable about not only LinuxCNC but a
great many other applicable and interesting things. I hope to both learn
and contribute here as I take this journey of my retrofit to LinuxCNC.
Thanks so much to Andy and all of you for your ideas and assistance. Peace

Pete

A very Merry Christmas, peaceful holidays and a Happy New Year to all of 
you!

You all have for another year made my life more interesting and enhanced 
my knowledge a lot, even though I am not directly participating for 
health reasons right now, but being in the community helped me to keep 
up with what's going on. Many thanks to all those who contributed their 
time and engagement to bring LunixCNC forward.

Precisely the effect I am looking for, but I'd probably leave out the

The attached patch (for master) adds an optional  tag that meter
understands. If supplied it will create a second blue needle, and a hal-pin
that controls that needle with the given name.
