Autofocuser Setup using:
- TMC2209
- Arduino
- 0.9degree Nema 17
- [MyFocuserPro2 FW](https://sourceforge.net/projects/arduinoascomfocuserpro2diy/files/ARDUINO%20FIRMWARE/)
The setup can be powered through USB, no extra power connector required.
If you need the extra torque, you can hook it up to 12V.
The Files should be printed with 10N/cm)
- [TMC2209 V3](https://www.amazon.com/TMC2209-heatsink-Microsteps-Ramps1-4-Mainboard/dp/B088T8T1HC)
- [Shield Board for A4988 / DRV8825](https://www.amazon.com/LM-YN-Printer-Stepper-Extension/dp/B01LWO9DI7)
- bunch of jumper wires
- bunch of M3 screws
- 1xM4 Screw
Wiring:
- Arduino 3.3V --> 5V on shield
- Arduino Ground --> Ground on shield
- Arduino 5V --> 9V on shield (alternatively connect external power, put ground together with Arduino)
- Arduino Pin 3 --> DIR on shield
- Arduino Pin 4 --> STEP on shield
- Arduino Pin 8 --> EN on shield
