Microduino-3D Printer

Microduino-3D Printer is a 3D printer controller, which includes a control board as well as a controller.

Feature

• Support SD card offline print (Only need to stack D]]) and adopt rotary encoder to control.
• Support long-distance wireless print, such as Bluetooth. Need to stack Microduino-BT.
• Plug-in module, easy for use and change.
• Small, powerful and practical. You can make a self-balance robot with stepmotor control.

Development

• Controller buildup
  • Connect OLED and base board
  • Fixate the panel, OLED and base board with screws.
• Connect the controller and 3D print board through dupont wires.
• Firmware download

The factory download firmware only needs to be re-download unless the system is damaged.

• Please make sure you built Microduino development environment and need to install Microduino-Core+(1284P 16M,5V) hardware support package. Otherwise, you need refer to Microduino Getting start
• Firmware download:
• You need to stack Microduino-USBTTL to download program to the core module.
  • Choose Microduino-Core+ (ATmega1284P@16M,5V) as the board.
• After the download, you can check the system through the controller. Here, we only provide drive board.
