Setup

The two wooden stands are fitted with the bearing holders and the axle with the „drum“ for the rope attached in the middle at the top. The stands must be aligned properly. The chain should already be placed over the large sprocket. The motors are attached to the stands using metal clamps and positioned so that the chain has sufficient tension. The motor drivers are screwed onto both stands below the motors. All dip switches need to be turned to the off position to limit the current to 4A and set it to the highest microstepping mode. Additionally, the ESP32 board is mounted on one of the stands. Everything is then wired according to the wiring diagram. A Cat 5 cable is used to transmit

the control signals to the motor driver on the other stand (3 m distance). Next, the middle column with the two metal rings, through which the rope must be threaded, should be placed centrally between the stands. The stands should be positioned so that the rope runs parallel and does not jam in the rings. The rope is then coiled as smoothly as possible without twists and placed near the reforestation stand (-stepsBackward). After that, the rope is laid over both drums and allowed to hang down on the deforestation side (+stepsForward).The screen is mounted at eye level next to the „player box“ at a suitable spot on the wall and connected via HDMI. Finally, the headphones are connected, completing the setup.

Now testing can begin.
