5.3 LCD Display Connection
Connect the MKS Mini12864 LCD display to the motherboard using the provided ribbon cables. Ensure correct orientation of the connectors.
5.4 Firmware Update
The motherboard requires appropriate firmware for your specific 3D printer model and configuration. You must update the firmware from the official GitHub repository. Refer to the GitHub documentation for detailed instructions on compiling and flashing the firmware (Marlin2.0.x, Klipper, or RRF).
6. Operating Instructions
6.1 Power On/Off
- Power On: Plug in the 3D printer's power cord and turn on the main power switch. The LCD display should light up.
- Power Off: Turn off the main power switch and unplug the power cord.
6.2 LCD Navigation
The MKS Mini12864 LCD display uses a rotary encoder and a button for navigation:
- Rotate Encoder: Scroll through menu options or adjust values.
- Press Encoder: Select an option or confirm a setting.
- Reset Button: Restarts the motherboard.
6.3 Printing
After successful firmware installation and calibration:
- Prepare your G-code file on a USB disk or MicroSD card.
- Insert the storage device into the motherboard's slot.
- Navigate through the LCD menu to select your print file.
- Confirm to start the print.
6.4 Advanced Features
- Filament Detection: If enabled in firmware, the printer will pause automatically when filament runs out, allowing you to load new filament and resume.
- Auto Shutdown: If configured, the printer can automatically power off after a print job is completed.
- Print Resume: In case of power loss, the printer can resume printing from where it left off (requires compatible firmware and settings).
7. Maintenance
- Cleaning: Periodically clean the motherboard and surrounding area to prevent dust buildup, which can lead to overheating. Use compressed air or a soft brush. Ensure power is disconnected before cleaning.
- Firmware Updates: Regularly check the official GitHub repository for new firmware versions. Updates can provide new features, bug fixes, and performance improvements.
