Thanks for all of the information! I particularly like the book list provided by William F.Adams. My reason for getting into OpenSCAD and 3D printing was the desire to build an AZ-EL tracker. It took months of learning about OpenSCAD, Raspberry Pi, gears, pulleys, stepper motors, etc. And it worked... mostly. It worked fine for the Sun, the Moon, planets, and stars. But it never really worked for my main goal, satellite tracking. Gears, bearings, and pulleys I get. I get stuck designing the supporting structures for those movements. Again, thanks for the info!
