5-axis possible?

[Thick8]

I was wondering if it would be possible to use the add-on 1 and 2 (8-pin) ports for 5-axis control. Building the hardware seems pretty straight forward. I would be willing to design an open source hardware solution if anyone can do the software part of it. I like contributing to the community but I lack the programming skills. Here's a link to my shared builds so you know I'm not just blowing smoke. https://www.youtube.com/channel/UCroXLHnirCH9a5ZsEa-LT2w
