This is the second version of the SOLAR_TRACKER  . I made this upgrade to improve some aspects that I didn't like from the previous version:

For example (maybe because I used PLA for gears) I noticed that some teeth were weared a lot.  And  sometimes  happened fatigue failures in some gears.

The main purpose of this version is to use a greater module wheele, but it was impossible to use that reduction ratio with 2.5 of module....TOO HUGE.

So i decided to change the geometry, I removed the arm and so the hinge is inside the panel. In this way I have big benefit of a very close centre of mass from the means that I could choose a 45 reduction ratio instead of  202 of the previous version.

I made changes only on the "Elevation" side of the project while the the other aspects are pretty the same.

I don't use anymore a potentiometer for the "homing" but two simple Endstops, and I'm working on adding a Accelerometer and Magnetometer for a better control.
