Point And Click Confusion
One other item that isn't clear to me. I am supplying 5V from the 5i25. I have nothing hooked up to the field power right now but I am also not making use of any I/O other than the step and direction. Is this ok? I just assume it is but...
Other than that, it seems to recognize the card, my LED (CR1) is lit. My amplifier is working (using leadshine tuning software). Just seems to be something minor with my configuration.

What must i select firmware fot the upper configuration ? And how can i define for six axis ? My mechanical is based on stewart platform.
These are configuration pictures and questions.

I am a beginner user for linux and linuxcnc. In addition i am a mechanical engineer so i have a weak electronic substructure. Thanks for your help.

The numbers are _not_ the physical pin numbers but are the component numbers.
You must look in the Mesa 5i25 manual to convert them.
The 6i25 and the 7i78 are not supported directly by pncconf.
You could select the 5i25 7i76X2 and then change all the 5i25 to 6i25 manually.
I would suggest to use the most current pncconf if it isn't all ready.

I also don't see these component numbers in the 5i25 manual. I understand now that connector 2 and 3 is referenced to the 5i25 and not the 7i76. I do see the "FUNCTION" from the manual seems to jive with "NUM" on the I/O Connector 2 tab. However, I don't see how the "NUM" on the I/O Connector 3 tab meshes with anything for P3 in the 5i25 manual. Regardless, I feel more comfortable with my settings as they were in my screen shots now.... then again, I would expect something to move.
I loaded up LinuxCNC with the settings as I have them shown and I jogged around while having the meter hooked up to the DIR pins on the 7i76. I expected to see the signal invert when reversing directions on that axis but I do not. Executing dmsg yields the following:

This looks like what I expect it to look like so I think I have actually configured this correctly. However, I am not getting any movement.

Do your drives require an "enable" input to be set?
Are the drive inputs differential? If they are not differential are the drive and 7i76 0V reference lines connected to each other?

I am using the Leadshine DM856. It has optocoupler inputs. Judging by the manual I see no reason I can't drive these with a differential signal which is what I prefer to do. I am currently driving them with differential signals from the 7i76 so I have not bothered to wire the common. I would still expect to be able to see the differential outputs swing with my multimeter when driving the axis back and forth.
One question I still have is regarding the power. I have not supplied any field power. I am simply supplying power to the 7i76 via the 5i25. My assumption is that since I am only using step and direction the field power is not necessary.
