That seems to replicate in HAL what the gearchange component does. I

if there are many index signals during motion, then use a 'near home'
swx to identify which one and home in one direction
the 'near home' switch should reduce the velocity so the index is reliable.
i used a 90 to 1 gearing on a 3R Caxis with a prox switch and dog to
identify which of 90 indexes

Jon, Igor,
i got it
maybe identifying the setup with a picture might be of use

I have a Bridgeport Interact 2 CNC mill and it has a back gear.
In back gear, the spindle turns at the -1/8 of the original speed, that is,
8 times slower and in the opposite direction.
I have an encoder on the driven pulley of the variable drive. Therefore,
when my mill is in straight gear, the
Oh, and one more thing: the index signal on the encoder, does not mean a
full turn in back gear. It means -1/8 of a turn. Will that be a problem?

Would anyone have an example of gearchange implemented in their config file?
Thanks, guys, this looks like it will fit my bill, I would just like to look
at the example.

That rather depends on how your existing system is set up.

Hi Igor;
I use the following Hal logic to maintain the spindle speed (S setting)
and direction when in Hi or Low gear on my Bridgeport. A micro switch
lets EMC2 know when the spindle is in low gear and the logic selects a
different scale and direction, so fwd is still fwd in low gear.
You should
