EQ1 Astro Tracker

A remix for 3ddruckqueck EQ1 Astro Tracker system. got an old stepper motor with short shaft so i'd to mount the pinion backwards. This lend me to modify the mounting plate design so i could attach the motor in the oposite position, underneath the EQ1 polar axis.

i also included oval notches for adjusting backslash of the gears (my printer still has calibration issues, and this helps to inprove gears mesh.

both gear and pinion are the same designed by 3ddruckqueck. gears requires breaking in. after some minutes readjust gear mesh and they'll run quiet. some grease helps too. also included a simple DSLR mount and a homemade knob for a 1/4" - 20 standard bolt.
