This high - performance mainboard is specifically crafted for the DreamMaker Overlord 3D Printer. As the brain of the entire 3D printer, it automatically analyzes sensor data and controls the actuators to smoothly complete the printing process. Built on the Arduino Mega2560, it offers a wealth of GPIO interface resources, making it perfect for various structures and motion control. It's also a great choice for DIY 3D printer projects. For easier secondary development, the schematic and interface of this board are publicly available. Specifications include an operating voltage of 5V, an input voltage of 24V/9.2A, and an ATMega2560 MCU. The XYZ motion axis stepper motors have a rated voltage of 4.6V, a current rating of 1.1A, and a step angle of 1.8°. The extrusion agency stepper motors feature a rated voltage of 3.6V, a current rating of 2.0A, and a 1.8° step angle. The heater has a rated voltage of 24V and a rated power of 60W. There's also a high - temperature sensor PT100 with a range from - 50 °C to 350 °C. Documents available are Marlin 3D printer firmware on Github, Marlin 3D printer wiki, User manual V1.0, Schematic, and Layout. The shipping list includes one DreamMaker Overlord 3D Printer Mainboard V1.0.
Using this mainboard is easy. First, connect it to your DreamMaker Overlord 3D printer following the provided schematic. Power it up with the correct input voltage of 24V and make sure the operating voltage is stable at 5V. When starting a print, the mainboard will analyze sensor data and control the motors and heater to complete the process. For DIY projects, you can use the released schematic and interface for secondary development. Remember to handle the mainboard gently as it's a delicate electronic component. Keep it in a dry and clean environment to avoid damage. If you're using high - temperature sensors, don't exceed the temperature range of - 50 °C to 350 °C. Check the user manual V1.0 regularly for any updates and follow the guidelines in the Marlin 3D printer wiki for best performance. When not in use, store it properly to extend its lifespan.
