i have used mode 2 on x and z. they are working.

ok thanks

Which combination of cards do you have?

Oops should have read the title.

That's a fairly odd combination, what hardware interfaces do you need?
There is no standard firmware for the combination, but it can be built easily
 

There's 7I76+7I85S firmware for a 7I80DB but not for the 7I76+7I85.
I can make this if you tell me which version of the 7I80DB you have (-16 or -25)

Note that Sserial cards don't need any card specific support in the firmware.
(as long as there is a sserial port, any sserial card is supported)

The 7I76 has 1 free sserial port and the 7I85 has 5 free sserial ports.

Just did that and it seems possible. Now the next question, which bit file should i use for this configuration (7i80-DB + 7i85 and 7i76 with the 7i87 connected to the 7i76)? thank u

I was running this computer over a year on 2.9.x with no problems.
Anything is worth a try, new Intel card on order. It should be here tomorrow.

Do double check this, but it should be possible to just wire the 7i87 to 7i76 using a cut off LAN cable, the Smart Serial connector, info on exact wiring is on the 7i76 manual.

Where did you read that? I would really like to delete that as it is just adding to the "buy a RPI" sickness spreading all over the web.
RPI is NOT required to run, it CAN be used to run LinuxCNC, any PC can be used to run LinuxCNC and Mesa cards.

On the Mesa subject, i do have somewhere a working 7i95 config if you need one, without the 7i77.
As for firmware, please do not proceed without consulting with PCW here, you seem to be bumping into some fishy info...
And for next time, when you have a 7i95 and you need to add analog outputs, use a 7i83 as 7i95 has encoder inputs. That is if you do not need all of the stepgens and encoders and analog outs and encoders...
