Mesa 7i96s firmware for Index (2.9 release) was created by vibram
Hello,
I'm looking for firmware for Mesa 7i96s with Index pin (release 2.9)
I followed Talla83 tutorial on Efinity but I have no clue how to implement the Index stuff.
Thanks a lot for your support

All normal 7I96S firmware supports index on the encoder.
Did you mean stepgen index support?

Yes exactly sorry, as I'm working on this, this is obvious but not for everybody
Stepgen index

If you want just one stepgen/encoder index on the 7I96s's built in encoder
interface, use 7i96s_esdi1.bin. If you need more, it depends on where
you want the index pins to connect. The 7i96sd_esdid.bin firmware
puts 3 stepgen index pins on the 7I96S encoder A,B,IDX inputs
(losing the encoder)

I absolutely need the encoder. However I only have 2 motors so is it possible to use the other axis step/dir instead? So pin tb1 14 and following?
Thank you

Step/dir pins are output only
So you need the spindle encoder and 2 step/dir indexes?

Yes please
Is there a way to see how you do (screenshot or whatever) in order to learn a bit also?

Here is 7i96s firmware that adds a stepgen index pin for all stepgens
Note that these have been added to the P1 expansion connector
so can only be used with TTL/5V level index signals. It's also advisable
to add a say 220 Ohm series resistor to each input if interfacing
machine I/O to the P1 FPGA expansion port to protect against negative
input spikes.

Thanks a lot I will first check what you modified in order to understand and confirm no other impact on my setup and then flash the firmware

Thank you again.
I struggle with the configuration
If I understand well I need to adapt this line in my Hal file but can't figure what should I put?
net xindex-enable axis.0.index-enable <=> hm2_7i96s ???
I connected my index on i/o 36 (P1)
Thank you for your help
