7i76 using a spindle encoder input for index axis0

An idea...

On the drive, I have a OCZ into open collector.

If I do this:

OCZ ---> relay ----> net x-index-enable hm2_5i25.0.7i76.0.0.input-00

What do you think ?

Index-enable is something linuxcnc controls to enable encoder count latching on
index

Indexed homing cannot be done without a full encoder input

Ok you have another card that 7i76 reference works.
just to use an encoder

One solution may be to use the parallel port and parport.
So I'm a encoder and I use his entry for the net x-index-enable.

OK ??

I think there is a misunderstanding of what the index input and index enable do:

1. index enable is an internal signal to linuxcnc used to enable index latching
of the encoder count when the index signal is detected
it is not useful to get the index-enable from an external source

2. The index input causes hardware/linuxcnc to capture the encoder count when
index signal is detected. If you want to use homing on index you must have a servo system
setup with encoder feedback. For a lathe this probably means 3 encoder inputs
(9 signals if all encoders have A,B,Z))

ok thank you for these precision.

For item 1:
index enable
What to add hal?

For item 2:

Not usable with my drivers closed loop
