I have a jog pendant with an MPG. A selector switch tells LCNC what the MPG is supposed to adjust, I have regular axes, feed override and spindle override set up there.
See : pico-systems.com/pendant.html
for more info, schematics, etc.
This is used with my Pico Systems interface boards, but should be easy to set up with Mesa as well.

Typically the Realtek MAC requires the DKMS driver for usable latency.

Not sure which thread is the best on this but searching the forum for "DKMS"
will find a thread that shows the Realtek DKMS driver installation details.

You are not guaranteed to see any change in the Z signal
as its a short pulse and quite hard to catch at the 1 KHz servo thread.
(especially with higher resolution scales)

This is why the actual index event is captured in hardware.

The index (Z) signal is only provided as a hal signal for debugging
or using it as a GP input. It's normally not of any other use.

If index enable goes false on an index event, the index was detected.
 

If you have a Mesa setup, you could add a 7I73 that will support up to 4
MPG encoders (plus buttons/keypad/etc) and unlike the Arduino, it's
real-time.

Hi Dylan,

Have a look through the docs, they should point you in the right direction.

You will need to flash the original firmware back onto the board as the Remora firmware will be loaded off the SD card with the original bootloader.

I'm working at designing a small CNC machine for milling lock set mortises and would like to incorporate automatic tool length detection.  I was wondering if a proximity switch could be used to accurately detect the tool tip.  The tool would be spinning slowly in the spindle and lower into the prox's detection field from above the switch.  The tool size, shape and material makeup should stay the same from one tool change to the next, so I shouldn't need to worry about a variety of different tools being detected differently by the sensor. 

Thoughts and opinions?  Think this could work consistently? Or would it be better to simply use a conductive pad with a lead connected to the tool or conventional normally closed switch.

yes, I checked all that with 4 encoders but I never saw any change in the Z signal. I think my .hal is compliant. Could there be a connection subtlety on the 7i96s card?

excellent! glad you got it sorted! now you should be future proofed too for 2.10 when it is officially released as stable!

I figured it out, I had to modify the math a bit (along with adding the stglue and RANDOM_TOOLCHANGER = 0 changes) but now it works perfectly. Not sure if it is something inherent to the Mazak index style ATC or if I had something wrong from the start when I used the sample configs as a reference to write the config for my machine. I just pushed the changes to my github attached above. I'll be sure to keep it public when I clean everything up and merge it to my main repo.

Thanks for the help!
