This paper deals with the implementation of a control system for a Delta 3D printer, which was carried out to enable its use in educational applications. A detailed diagnostic was performed on essential hardware components of the Delta 3D printer, including the Arduino MEGA, RAMPS 1.4 board, stepper motors and their drivers, micro switches, display module, and other electronics. A customized version of the Marlin firmware, adapted for a Delta configuration, was then installed on the Arduino MEGA microcontroller. Key parameters such as build plate dimensions, print height, Delta radius, motor microstepping, and maximum motor speed and acceleration were configured. To optimize stepper motor performance, reference voltages were adjusted, and TL smoothers were installed to ensure stable and quieter operation. The final system evaluation included measuring motor voltage levels, verifying filament flow rates, checking the dimensional accuracy of printed parts, and validating the parameter setup. After hardware and firmware calibration, various slicing software tools available online were tested and compared. The aim of the analysis was to identify the most suitable slicing software for the optimized Delta system, as well as the optimal configuration of its parameters, in order to achieve the highest possible print quality
