Not for now, you need to use the LinuxCNC pncconf Wizard from the menu to create a config, then check if everything works as expected.
Also do pay attention to setting the 5i25 and 7i76 to be powered from the 5i25, both of them have jumpers that have to be set correctly for that purpose.

On the 5i25 card I have W1 up, W2 down, W3 up, W4 up, W5 up.
On the 7i76 I have W1 right, W2 left, W3 left, W4 right, W5 right, W6 right.
Can you help me verify these please ?

5i25
W1 down
W2 up <<<< this one is for the P3 port where the 7i76 will be connected
W3 up
W4 up
W5 up


7i76
W1 left <<<< this will set the board to use only one field power supply, Right ONLY if you have separate power for Vin and Vfield.
W2 left
W3 left
W4 depends on encoder left=TTL, right=differential
W5 depends on encoder left=TTL, right=differential
W6 depends on encoder left=TTL, right=differential

I have a good feeling about it. I will let you know as soon as I can get to the shop....

That is wrong, both of them go to + , and they have a common ground

Thanks again for all the help Tommylight, BTW is there any particular supplied configuration choice I should choose in the wizard ?
There are so many choices and no one in particular stands out to me.
