I’ve been noodling over different ways to build a router lift using marlin and a lcd display. Probe z and move axis would be enough. But adding a fence? I’d totally cut slots into my tablesaw extension of the fence had pins or something that could drop in. Some cheap ballscrews would probably do the job nicely, maybe even some anti-backlash nuts on leadscrews. Cost a lot less than than 2k, i know that. But that program…
Pretty cool.
Another use for a Jackpot board - 2 axis or even 3 if you made a sliding stop as well as the fence move.
Found an open source build that’s similar
And another, beefy construction.
Looks a lot like a move and pause, hit the button to move to the next position.
I think you can do it!!
Move and pause, sure. But calculating all the moves for all those different features…
Don’t say you weren’t thinking it, too…
Wouldn’t you just need to know teh first postion and then the distance apart for each cut after that.
For example, 1/2" from the edge, 3/4" apart. You chose which edge is your reference. Then for a finger joint you use the same distance apart different start point by one tool diameter? I doubt that software does any more than that.
Worst case you can build a little web calculator or spreadsheet to do the distances. I think it can be done, and finger joints would be the most complicated, but not by much.
I’d take good plans for a manual router table… Never found any that did satisfy me. 
Spreadsheets are my jam
