Mesa 7i96s firmware for Index (2.9 release)

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?
