7i92TM, not sure about the exact lettering, but it should just plug into the 7i76, makes for a much cleaner install.

Just wondering if the 7I96S will run with pathpilot? I know that PP is using linuxcnc 2.8.0-pre1.

Seems not...
LinuxCNC 2.8.4 has been released.This release, unusually soon after the 2.8.3 release, is mainly to address a side effect of the ongoing chip shortage. It has become difficult to build most of the popular Mesa hardware interface cards. One card that is reasonably available, the 7i96S is not supported by LinuxCNC 2.8.3. This release adds support for the 7i96S to the 2.8 branch.

To Filipe and Peter:
What is the status 7i97, 7i95, 7i77, 7i96S, 7i92TM?
For now, i need a 7i97 or 7i92/7i77, but i can mix and match from the above.
Preferably in Portugal as this will be ordered through a company in Austria, same company/owner already ordered twice from eusurplus.
I would really hate to yank out mine from the Mazak, but would submit if there is 7i77D in the mix! :)
Would make the wiring neater in the Mazak as i had to make inverters for every output on 7i77 and 7i84.
Thank you.

The only Mesa stuff not used yet is a 6i25 and a 7i73, i am used to having a full suitcase. :(

Filipe should have 7I96S + 7I95T + 7I92TM later this month

We should have 7I97T protos (7I97 replacement) soon
7I77s will be a while as they require re-design

An interim solution for Analog drives is a 7I95T and a 7I83,
7I96S+7I89+7I83 or the 7I97T proto

The 7I77 replacement (7I77U) like the 7I76EU can do sinking or sourcing outputs
under software control

Sorry, he does still have a low amount of 7i92TM, but not the rest.

OK, so leaving this for later, maybe.
The thing is, they lost the 7i77.
They have 2 machines (Elumatec and Hurco), both use 7i92 or 5i25 with 7i77 and 7i74 and 7i70 and 7i71, but someone took 7i92 form Hurco a while back and now they lost 7i77, the rest is there. Hurco was not used waiting for a big a$$ VFD and Elumatec is in daily use. They also have a plasma with 7i76E and THCAD in daily use.

An interim solution for Analog drives is a 7I95T and a 7I83,
7I96S+7I89+7I83 or the 7I97T proto

Hmmm how come i did not know about 7i83??? That can also be used through a 7i74 or 7i96S or ....

Oh how niceeeee, no more soldering mess for me! :)

Welectron in Germany seems to have over 10 of 7i96S

Question, does adding a 7i85 or 7i85S to 7i96S do encoders? I always mix those as i never used the 7i85/S and still not sure what it can do, despite reading several times, i keep messing those up. I think i read here that one of those can be used for encoders, so do not shoot if i am wrong! :)

Thank you for everything, especially for the awesome support.

Thinking out loud, how viable is :
ethernet
3 step/dir
3 encoders
at least 2 of smart serial
a single IDC26 header, or not
some IO
no spindle
?
Probably not much as it will need the FPGA, but maybe, just maybe something smaller with more availability?
-
My brain is mush from looking at cheap servo drives/motors and their less than ideal info, but seems the trend is always have the step/dir inputs.
Also, plenty of lathe retrofits around here, so total of 3 needed, plenty of mills use modbus/RS485 for spindle control so again 3 total.
