Hint: The Universal Controller is a LCD-screen equipped controller that is capable of controlling 3D printers, CNC machines, welders, filament makers, automated machines, or any other applications where a microcontroller runs different actuators, sensors, or power elements. It is a platform consisting of RAMPS, LCD screen, power supply, power outlet, and power handling SSRs, and can be connected to external stepper drivers, solenoid valves, or other power elements. Equipped with an Arduino Mega, it can be used to control just about anything that requires a 100 kHz or lower control signal. See 2019 work on this at OSE Design Manual - Universal Machine Controller

About the Universal Controller - Design and Uses

The Universal Controller consists of a 3D printed mounting panel, which holds all the components. This panel is printed with a 90 degree bend, and is straightened with a heat gun as shown in 4D Printing. The main components for the D3D Pro 3D printer are 5:
