using the gearset from orbiter 1.5, chep cube 24mm in z

[tnap1979]

so i wasnt able to get a galileo 2 gearset, but noticed with a bit of work and effort, i could get my orbiter 1.5 gearset working...
but when i did a test print on my LDO v0 build, with a chep cube as my usual,
i get 24mm in z height with the cube, using the provided config information...
am i to assume that the orbiter gearset must be different then ?
and now how to get the proper z height??

i used the cad files for both orbiter 1.5 and galileo 2 to figure out the difference in the gear ratio...
this g2z project uses a 9:1 for galileo 2, google gemini calculated my ratio to be 7.5:1 with my 10t motor pinion sun gear, 27t planet gears, 65t ring gear..
just printed a cube again, came out to 20.04mm
