First outside tests of the rotator with a 900/1800 GSM antenna. No satellites received, but ADS-B came in strong.
Homing of both azimuth as well as elevation
Testing accuracy of both azimuth and elevation. When homing is done right there are negligible deviations. The TMC2208 make the operations much quieter. The only time you can really hear the setup is when both steppers are activated.

Both AZ and EL steppers installed and the first test. The noise is down due to the A4988 drivers, but still too much for my taste.

First test with the elevation stepper installed. The TB6600 stepper driver is the cause of the huge noise the stepper motor is making.
