Subject: Re: [Emc-users] spindle orientation help for a 7i77 card looking for
    configs to study

peter you found it lol!

I have the spindle turned on by a standard output from the 7i77 card anyway
so didn't check that the spindle enable signal was turning on the
hm2_5i25.0.7i77.0.1.spinena pin

i just went through it again and double checked stuff and netted the
spinena pin also and it works.  I didn't realise that the analog out value
only works if the spinena is on.  but I know now

so next issue is I have a 5v pnp prox that I want to put on the spindle for
a index sensor as my motor/gearbox ratio is not 1-1.

PCW can I use a 5v pnp sensor straight into the 7i77 encoder input same as
I would do with the field io?


The encoder inputs have a 2K pullup resistor to 5V so you would need a relatively stiff pull down resistor on the output of the PNP sensor for that to work (say 270 ohm)


ps john.  I will add post up my config once I have it working real nice for
everyone to copy.  anyone that has a 7i77 card should be able to just plug
in and get spindle orientation so long as they have a suitable vfd


regards

Andrew

hey everyone.

i have been messing around all day with my cnc mill trying to get spindle
orientation working so that I can get my toolchanger working



I found a video on youtube from Tallas83 that showed what  I want to do
but
he used a 5i20 card and 7i33 and I am having trouble converting it to a
standard 7i77 mesa card set up.


https://www.youtube.com/watch?v=EoXoOYSFY2Q


I got it to load the new config eventually had to change all the motion
pins to spindle.0 stuff but still getting a bit stuck when I issue a m19
r0
command the spindle locks but doesn't rotate.  and I can see on my vfd
that
the frequency reference is not getting through even though in the hal
configuration the hm2 analog 05 output is showing a value.  If I switch
back to my old config it fires right up so hardware is fine.



Is hm2_5i25.0.7i77.0.1.spinena true?
(analog out 5 has a separate enable)



does anyone out there have this working that can help.  I don't need too
much hand holding I think and I have played with linuxcnc for several
years
now.  just getting stuck up against a wall.

regards

Andrew
