Print one of each of the 3d printing files. Unscrew the Moteus board from its stand.
Instructions to upload (flash) the Torquetuner and the Moteus board firmware and configuration files can be found here.
Read and follow ALL the instructions at before upload it to the board. There are some steps to prepare your machine and the ESP32 before flash it for the first time.
Glue magnets to the bottom of the electronics case and the top of the PSU case. These magnets need to be able to connect together.

Figure 2: All the electronic components
- Start with the Moteus board.
- Solder a wire from a wire from the 3V pin to the VIN pin on the regulator.
- Screw the moteus board onto the top plate of the electronics case.

- Assemble the Adafruit LCD I2C Shield according to the instructions given on the adafruit website. If your M2 Screws are too short, you can screw the shield onto the case before soldering the LCD as shown in figure 4.

- Connect the JST-ZHR cable to the moteus board. The pins from the JST ZH cable (from left-to-right, that is starting closest to the ABS label on the board) are: 3.3V - SCL - SDA - GND
- Solder the 3.3V pin to the 3.3V pin on the TinyPico.
- Twist another wire onto the SCL, SDA and GND wires. We will use solder these extra wires onto the LCD shield
- Solder wires for SDA, SCL, GND and 5V as shown the Detached Usage section on the Adafruit product page.
- Solder the 5V wire to the VOUT pin on the 5V regulator
- Solder the a wire from the GND pin of the 5V regulator to the other ground pin on the TinyPico.
- Solder the SDA, SCL and GND wires coming from the Moteus board and the LCD Shield onto pins 21, 22 and GND respectively on the TinyPico.
- Slot the TinyPico on the opening.
- Attach the Stub at the end to stop the TinyPico from sliding out of the opening.
- Close the electronics case and screw 4 M2 screws on top of the case.
- Power on the motor to test the LCD turns on. Note you may need to change the contrast in order to see the words on the LCD.
