5. Setup

The MALYAN M300 comes fully assembled and factory-calibrated, allowing for quick setup.

1. Unpacking: Carefully remove the printer and all accessories from the packaging.
2. Placement: Place the printer on a stable, level surface in a well-ventilated area.
3. Filament Holder Installation: Attach the filament holder to the designated slot on the side of the printer.
4. Power Connection: Connect the AC power adaptor to the printer and then plug the AC power cord into a suitable power outlet.
5. Power On: Press the power button to turn on the printer.

6. MicroSD Card Insertion: Insert the provided MicroSD card, preloaded with test models, into the MicroSD card slot.
7. Initial Bed Leveling Check: While the printer is factory-calibrated, it is good practice to verify the nozzle-to-bed distance. The optimal distance should be approximately 0.1mm, similar to the thickness of a standard A4 printer paper sheet. Adjust if necessary through the printer's menu.

6. Operating Instructions

6.1 Loading Filament

1. Place the filament spool onto the filament holder.
2. Feed the filament into the Bowden extruder.
3. Preheat the hotend through the printer's menu to the recommended temperature for your filament type (e.g., 190-220°C for PLA).
4. Once heated, gently push the filament until it extrudes from the nozzle.

6.2 Starting a Print

The M300 supports printing from a MicroSD card or via USB connection to a computer.

1. From MicroSD Card:
   • Ensure the MicroSD card with your .gcode print file is inserted.
   • Navigate the printer's LCD menu to "Print" and select your desired file.
   • The printer will begin preheating and then start the print.
2. Via USB Connection:
   • Connect the printer to your Windows or Mac PC using the Micro USB cable.
   • Install and configure a compatible slicing software (e.g., Cura, Repetier Host).
   • Load your 3D model (.stl, .obj) into the slicing software, configure print settings, and slice it to generate a .gcode file.
   • Connect to the printer through the software and initiate the print.

7. Maintenance

• Cleaning the Print Bed: After each print, allow the print bed to cool down. Use the provided plastic scraper to carefully remove any residual filament or prints. A clean bed ensures optimal adhesion for subsequent prints.
• Nozzle Cleaning: Periodically check the nozzle for clogs. If a clog occurs, preheat the hotend and gently push a thin needle or cleaning filament through the nozzle to clear the obstruction.
• General Cleaning: Keep the printer free from dust and debris. Use a soft cloth to wipe down the exterior and moving parts.
• Filament Storage: Store filament in a cool, dry place to prevent moisture absorption, which can degrade print quality.
