PathPilot Lathe with 6 place turret

if the LEDS never light up. I would check that the 7I76 encoder inputs are jumpered to match the encoder type
does the encoder position change when you rotate the spindle? Also are you sure you have the correct firmware?
( stock Pathpilot will re-write the 5I25 firmware with Tormachs firmware )

PCW,
I using the mesa/5i25_7i76x2.bit file, I moved the jumpers over to the left (single ended input) for the us digital e6-1024-500-ie-s-d-d-b
encoder. I show 4096 counts per revolution, but have no way of confirming index pulse.

You can check index with halcmd/halmeter:

halmeter spindle-index-enable

halcmd sets spindle-index-enable true

then watch spindle-index-enable as you turn the spindle, it should go false on index detection

Pathpilot doesn't let us access most of halcmd and halmeter functions.

Here is the code in the post GUI file that displays status on screen, the encoder count works.

net spindle-encoder-count hm2_5i25.0.encoder.00.count => tormach.encoder-count
net sig1 => tormach.encoder-a
net sig2 => tormach.encoder-b
net sig3 => tormach.encoder-z

I do have Pathpilot controlling my spindle, but can't tell if it's using the encoder to keep the spindle at speed.

You should be able to run halcmd and halmeter with
admin halcmd
admin halmeter
or start Pathpilot in a window and run the commands from a terminal

I really can't imagine trying to get this working without a tool set that lets you see what's happening behind the curtain...
In fact getting a working debug tool set should be the first priority

Closed loop spindle speed control will require modifying the hal file
( and this again will be much harder than it needs to be without having a working debug tool set )

both ADMIN HALCMD and ADMIN HALMETER work in PP at least it does in mine.
also if you check for messages I and another got ADMIN HALSHOW working that should help as well.
you can also find a linuxcnc build that matches PP then you can copy files needed over to PP if things are missing. (i do have the old binary.hybrid.iso from that version is anyone needs it)

I'll check later on admin halcmd and admin halmeter. For now I can tell you that everything seems to be working ,the spindle speeds up when tool get closer to center. If i unplug the encoder while lathe is cutting all axis come to a stop until I plug encoder back in (rpm gauge also goes to zero).

I'm fighting a little bit with if this thing is running in diameter or radius mode.

Ok,
I found my error in the x axis ,I forgot that x only moves half the distance. I had my stepscale set for the full distance.

smgvbest,
How do you see halmeter ? I've tried -

admin halmeter spindle-index-enable
admin halcmd sets spindle-index-enable true

in the mdi line but nothing happens

Thanks'

Here is a good run ,sort of.
