Can you contol a servo thru the cheap breakout card?

i use only wormgear backlash free from Maedler
or as not the big load simply timingbelt 3:1 as i mentiond above give it a shot

IF YOU can spend the money or are willing for a harmonic drive go for it
nothing better then this

Yes, I'm trying to keep within my budget. I've seen the planetary reducers online also, I'll check them out

It looks like 12 to 1. Reduction.



I just found a 25to1

With that you still need to find the servo (or stepper) motor and the drive. And you probably need some big bearings too.
The FHA-25 that I suggested earlier already has all those things, and the bearings are rated for a load of 500kg radial and 1400kg axial.

I built a couple of other designs (geared-down stepper and motorised worm-drive dividing head) before deciding to spend the money on something perfect for the job instead.
