OK, but still looking for the book *HAL for Dummies* 
from HAL
setp hm2_7i76e.0.encoder.00.scale 1000
setp hm2_7i76e.0.encoder.01.scale 1000
setp hm2_7i76e.0.encoder.02.scale 2000
Assuming this is for the X/Y/Z, where do this be connected to the axis in question
7i85S 1st 2nd 3rd encoder inputs
Want to have spindle encoder on 4th encoder input, what syntax in hal for this.
Now 360ppr encoder so the INI will have to be ENCODER_SCALE = 1440

I'm feeling very despondent here today. Wish I just had to sort out how to make a spindle work instead of a plasma torch!

Definitely not needed, just measure your progress by the blood on your workshop floor.OK, but still looking for the book *HAL for Dummies*

I assume that you have seen:
linuxcnc.org/docs/2.7/html/hal/intro.html
and
linuxcnc.org/docs/2.7/html/hal/basic-hal.html
and that these do not meet your requirements?
Choose the N and MM any way that you fancy.
If you are using a PID component for each axis (this is optional, but pncconf currently sets things up that way) then you also need(That is the same "some-signal-name" as the above, and you can combine them all on one line, or split over 3 lines, as you prefer)
All the motion pins are listed here:
linuxcnc.org/docs/2.7/html/man/man9/motion.9.html
And the pid pins at:
linuxcnc.org/docs/2.7/html/man/man9/pid.9.html
Are you writing the HAL from scratch or using PnCConf?
