Yep, close Brett, not sure where you got the 2:1 from.
(Im assuming you guessed by the sizes of the toothed pulleys?)
Stepper 1.8 deg/step into 60:1 reduction then
Toothed pulleys 1.8:1 then finally
Edit:"sorry: it's actually 1.75:1! (24Tpulley drives a 46T pulley)
Worm driving 317 teeth worm gear 317:1
I get 33285:1 (RA axis only BTW)
That's possibly not a final value either, for the record.
Steppers as you know all have comfort zones.
This setup is close to that, but it's not ideal for fast
half step slews.
How's your options going? Has anything come together yet?

Steve
