Coil winding machine
SAMATIC-268-SR

On the left side, we see an old PCB that has been damaged. Despite replacing one of the components, the board still did not work. On the right, there is a new main PCB which is directly connected to the Raspberry Pi.

On the left side, there is an old circuit board. On the right side, we see a new PCB that is connected to a tachometer, a stepper motor, and sensors responsible for managing transitions between individual coils.

On the right side, we see a new board responsible for controlling the clutches and the rotational speed of the main motor.

The first photo shows the old control panel. The following images feature an entirely new panel equipped with a 10-inch touchscreen. The last photo displays the wiring connections and the core of the machine, the Raspberry Pi 5.

After repair, the machine is powered by Raspberry Pi 5 visible in the first photo. This compact but powerful computer has two HDMI ports, which allowed me to install an additional monitor to display customer orders. The second photo shows the available external ports: 1x HDMI and 2x USB.
