Interesting a double decker. What sleeves will you use?
So you are the
guy?
You have two strokers, so you should use two sets of LLLRRR axes - and as you don’t support L12R12 (moving and tilting stroke axis) that’ll be L0, R0, L3, R3
As for funscripts, add L3/R3 support in your MFP settings and name scripts .L3.funscript and .R3.funscript
It’s actually theoretically a 1-6 decker but probably only 1-3 linear strokers is practical. I have other plans for the three currently open base slots.
I have shuttles (the inner receivers) already for Quickshots and Youcups (very short stackable sleeves).
No, much better 
So it’s SSR1 with two sliders?
btw have you checked SSR1 beta stls?
Quick progress update: have written most of the needed software, bought all the needed hardware, fried or soldered-to-death half of the needed hardware, adapted CAD models appropriately and have tested two different motor tracks individually. Will soon start simultaneous testing with manual control and afterwards hook up MFP and watch it fall apart, catch fire or both.
Oh, I made some CAD models for a pitch/roll solution too.

It’s ‘an SSR1’ only in that I’ve reused the motor-and-pulley idea and the motor controller. The STLs aren’t much use to me unfortunately.
