Equatorial mount for DSLR

This is a remix of the equatorial mount of SimonRob. Check out his instructables for more details on how to assemble https://www.instructables.com/id/Equatorial-Mount-for-DSLR/
Changes:
-Changed motor to nema 17
-Added another reduction (4:1)
-Changed to chevron gears
-Replaced all screws with M3 (was M2.5)

The reductions are 6:1 then 4:1 so with a standard 1.8deg stepper you get
4800 steps per revolution
76800 steps per revolution with 16 microsteps
1228800 steps per revolution with 256 microsteps (close to 1 arc-second)



I have assembled the mechanics but I have not yet done the electronics or tested it yet, I will use an Arduino with a TMC2208 driver.

I will make the following changes someday:

-Add clutch mechanism to “support”. Now the only way balance the support/camera assembly is to loosen the setscrew witch is not ideal.
-Change the endstop from the manfrotto mount to the “body” to the large pinion does not need to be removed to separate the two.
