Hi All,
I want to motorise my EQ3 by adding two NEMA 17 steppers.
I'm a bit confused with all the ratios and the advantages & disadvantages of direct, belt or geared connection, please be gentle!
I think we want R.A. and Dec. to be quick and accurate to slew but R.A. to be slow and accurate when tracking, so it would be great to use microsteps?
What are all the gearing solutions trying to do, slow down or speed up R.A. and Dec.?
Ideally I would directly connect the steppers to the R.A. and Dec. control shafts.
So I need brackets, does anyone sell what I need, just the brackets?
I found this:
https://www.astroeq.co.uk/tutorials.....php?id=ratios
Supposedly the worm gear ratio for R.A. is 130:1 and Dec. is 65:1.
I want to use "uStepper S":

It uses the TMC2208 which has a 1/256th microstepping interpolation algorithm.
Thanks for looking!
Cheers
Richard
