I was thinking a slot saw (gray disk) could be used, centered on the
gear
I do not know much about CNC operation but need to ask a question about
the operation similar to this gear cutting.

Thanks or very detailed reply. I will try it later today. One thing...I am
using steppers, do I need to run the functions for the servo threads?
Thanks again

I've seen that in operation and used it at a show here in the UK, it's
not slow, gear cutter rpm was about 2500 rpm and you can stuff the
cutter through the blank

If you are going to use your parport to drive the step and direction
Kirk
I have added..
loadrt hal_parport cfg=0x9000
addf parport.0.read servo-thread
addf parport.0.write servo-thread
to my hal file (hopefully in the right places). Can I not configure the pins
through the step config wizard?

No, you can't use stepconf
This is where Stepconf can help the someone less versed in the config files
though - you can make multiple machine setups and then go through the .hal
and .ini files and marry the two together to get the results you want
without really having to know the details of the hal and ini files.

In theory, this can be done. A thin slitting saw would deflect
too much to get an accurate tooth profile. You can buy gear
tooth cutters and run them like this, and it will go much
faster, which is still fairly slow.

Going throuogh the schematics for my CHNC the limit switches and the
home switch have three terminals PLUS MINUS and ZERO. Are these voltage
or polarity dependent or are they simple switches? Also the turret
encoder shows an A B C and D outputs. Are these binary or BCD and why 4
lines when 3
The description PLUS MINUS ZERO refer to 3 different sensed positions of
the slide, and dont say anything about the voltages.
Your schematics likely show a voltage going to them, or a pull up
resistor tied to them. You really have to look at the schema for that.

THE ABCD on a turret makes me think the encoder is very coarse and the
information ABCD is really just a 4 bit count of position. This is more
credible if your turret has less than 17 positions.

Aaron,
Since you indicated that you are adding a second port you need both
ports in your config statement:
loadrt hal_parport cfg=0x0378 0x9000
Here is how I set up my reads and writes: (not using steppers
requires adding them to the base-thread not the servo-thread).
