@LangdonS, he has 2 of Mesa 7i96S, so why are you suggesting he use parallel port testers?
Not helpful, just confusing.

@ffffrf
trying to clear things a bit, so you have
1 single PC
2 of Mesa 7i96S
2 of separate machines
Is that correct? Assuming yes
From that, PC works properly with Mesa1, machine works properly with Mesa1, correct? Assuming yes
That same PC with the Mesa 2 works for steppers but IO does not work, right? Assuming yes
-
Do you need to run both Mesa/machines at the same time? Assuming no
I am pretty sure 2 Mesa can be run, but not two instances of LinuxCNC, although there was some talk about that.
-
Assuming all of the above is correct:
-There is no need to change Mesa board address, nor change PC address at all to use both cards, but not at the same time. Leave the PC at 10.10.10.11 and both Mesa at 10.10.10.10. That reminds me, the networking on your PC is not set correctly despite working intermittently as it has two different names assigned to the same interface, and this must be corrected for reliable connection.
-regarding non working IO, i suspect you might have changed the serial ports on the PncConf wizard, but again, this is my assumption and as such might be wrong.
-easiest way = make a new config, do not change serial ports numbers, see if that works
or
-open both hal files, for Mesa1 and Mesa2 with a text editor (do not use office stuff) and check the "loadrt" lines at the top of the files, see if they are the same and if the sserial string is the same
-
Just in case, you can make as many config as you like, you can have several configs for the same machine with say different speeds or different accelerations or different limits or.... so feel free to make new configs till you get things working as you like them to.
Wow this was long....

Ok i just saw the attachments,
this is on Taig new
net min-x <= hm2_7i96s.0.gpio.001.in
while this is on Modlathe
net min-home-x <= hm2_7i96s.0.inm.00.input-00-not
not the same pins, and i do not mean the number, probably choosing the pins on the wrong page of the wizard ???
Damn, i am making a lot of assumptions tonight, i better go sleep, it is 3:33AM here!

Can i assume you missed my last post?
Also, the Mesa IP is 10.10.10.11 on one of those hal files, should be 10.10.10.10 on both files.
