Which Do I Use: PnCConf or the Config tool from GitHub

Did you verify the that the firmware you are using matched your interface pinout?

Also unlike parallel port setup (that tend to have large inherent step lengths)
the 7I92 will generate very close to the actual requested step lengths
so make sure that these have plenty of margin (start at 5000 usec minimum)

As best I can tell, but truly I am not 100% sure without any sort of CLEAR documentation mapping which goes where. I have looked at the G540 pin file, and I have tried to match it up as best I can to what is shown in the PncConf GUI, but it really is not clear, as some lines don't have numbers, and they don't go in any discernible order, and some signals are showing up twice. Really not intuitive or documented/implemented well.

You check whether the pinout matches your hardware by looking at the .pin file.
This is independent of pncconf. Are you saying a G540 configuration matches your hardware pinout?

Yes, the pinout of my controller matches the G540 pin file.

I appreciate your help, but it really seems that this product needs a LOT more work in terms of documentation and software implementation.

I have to say I am REALLY disappointed with this purchase. This is not a very complete, finished product. It is really a testament to how un-finished this is when It has taken HOURS of my time combing through forums and web pages and docs and youtube and other stuff, and I STILL cannot get enough information to output 3 simple step and 3 simple dir signals out one port. I don't event have e-stop, limits, or a spindle!

I am really sad about this because I have used LinuxCNC for years using the parallel port without issue and due to PC failure needed an alternative.

I have just requested instructions on how to return this for my money back.

If you cannot get motion on all three axis, its most likely
that the loaded firmware pinout does not match your hardware
or that the step times are too short for your hardware.
