3.3 Filament Loading

1. Mount the filament holder onto the designated slot on the printer.
2. Place the sample PLA filament spool onto the filament holder.
3. Gently feed the filament into the extruder's intake hole until it is gripped by the gears.
4. On the printer's interface, select the 'Prepare' menu and choose the 'Load Filament' option. The printer will heat up and automatically feed the filament through the hotend until it extrudes from the nozzle.

3.4 MicroSD Card Insertion

Insert the provided MicroSD card, preloaded with printable 3D models, into the MicroSD card slot on the printer. Ensure it is inserted correctly until it clicks into place.

4. Operating Instructions

The MALYAN M300 features an intuitive user interface for straightforward operation.

4.1 User Interface Overview

The printer's interface consists of a clear display and button controls. Key menu options typically include 'Print', 'Prepare', and 'Move'.

4.3 Starting a Print

1. Ensure filament is loaded correctly.
2. From the main menu, select 'Print'.
3. Navigate through the files on the MicroSD card using the interface.
4. Select the desired 3D model file (.gcode format).
5. Confirm your selection to begin the printing process. The printer will automatically heat up and start printing.

4.4 Printing from a Computer

The M300 is compatible with slicing software such as Cura and Repetier. You can connect the printer to a Windows or Mac PC via a USB connection.

1. Install your preferred slicing software (e.g., Cura) on your computer.
2. Connect the printer to your computer using the provided USB cable.
3. Configure the printer settings within the slicing software according to the M300's specifications (refer to Section 7).
4. Load your 3D model (.stl, .obj) into the software and slice it to generate a .gcode file.
5. Initiate the print directly from the slicing software.

4.5 Pausing and Canceling Prints

During a print, you can typically pause or cancel the operation through the printer's user interface. Refer to the on-screen prompts for specific instructions.

5. Maintenance

Regular maintenance ensures optimal performance and longevity of your 3D printer.

5.1 Cleaning the Print Bed

After each print, carefully remove any residual filament or debris from the print bed using the provided scraper. For stubborn residue, a soft cloth dampened with isopropyl alcohol can be used. Ensure the bed is dry before starting a new print.

5.2 Nozzle Maintenance

The all-metal hotend is designed for durability. If you experience extrusion issues, the nozzle may be partially clogged. Refer to online resources or MALYAN support for detailed instructions on how to safely clear a clogged nozzle. Always ensure the hotend is heated to the appropriate temperature before attempting to clear a clog.

5.3 General Cleaning

Periodically wipe down the exterior of the printer with a dry, soft cloth to remove dust. Avoid using abrasive cleaners or solvents.

6. Troubleshooting

This section addresses common issues you might encounter with your MALYAN M300 3D printer.

6.1 Print Not Sticking to Bed (Adhesion Issues)

• Clean the Print Bed: Ensure the print bed is free of dust, grease, or old filament residue. Use isopropyl alcohol for thorough cleaning.
• First Layer Height: Although the M300 has auto-leveling, ensure the first layer is extruding correctly. The nozzle should be close enough to the bed to slightly squish the filament, but not so close that it scrapes.
• Print Bed Temperature: Ensure the print bed is heated to the recommended temperature for your filament type (e.g., 50-60°C for PLA).
• Adhesive Aids: Consider using a thin layer of glue stick or painter's tape on the print bed for improved adhesion, especially for larger prints.

6.2 Filament Not Extruding (Clogging)

• Check Filament Path: Ensure the filament is not tangled on the spool or obstructed before entering the extruder.
• Nozzle Temperature: Verify that the hotend temperature is set correctly for your filament.
• Clear the Nozzle: With the hotend heated, try manually pushing filament through. If it's still blocked, a thin needle or acupuncture tool can be used to gently clear the nozzle opening. For severe clogs, a 'cold pull' or nozzle replacement might be necessary (consult MALYAN support).
• Check Extruder Gears: Ensure the extruder gears are clean and gripping the filament properly.

6.3 Poor Print Quality (Layer Shifts, Stringing, Blobs)

• Slicer Settings: Many print quality issues stem from incorrect slicer settings. Experiment with retraction settings (for stringing), print speed, and cooling settings.
• Filament Quality: Ensure you are using good quality filament and that it is stored in a dry environment. Moist filament can cause bubbling and poor extrusion.
• Printer Stability: Ensure the printer is on a stable surface to prevent vibrations that could lead to layer shifts.
• Mechanical Check: Inspect the printer's belts and moving parts for any looseness or obstruction.
