Study Notes
Safety Instructions
- Be mindful of potential hazards when operating the 3D printer.
- Ensure proper ventilation and avoid contact with heated components.
Printing Parameters
- Temperature Parameter: The printer's temperature (nozzle and bed) can significantly impact print quality.
- Software Parameter: Configuration settings in the slicer software (e.g., Cura) influence the final print, such as layer height, infill density, and print speed.
- Electrical Parameter: Correct voltage adjustment is essential (110V/220V) for safe operation.
Assembly Instructions
- Follow the illustrated assembly instructions for proper setup.
- Prioritize proper wiring for the main board as per the diagram.
- Ensure the platform is leveled correctly for optimal adhesion and print quality.
Cura Instructions
- Install Cura, a popular slicing software, for preparing print files.
- Familiarize yourself with machine settings, basic and advanced options for customizing prints.
- Learn how to load and manipulate 3D models in Cura, including scaling, rotating, and positioning.
- Save the Gcode file (the instruction file for the printer) in Cura, making sure it utilizes English letters, underscores, and spaces for proper compatibility.
Online Printing
- Install the necessary driver (CH341SER) for online printing via USB connection.
- Configure Cura for online printing, selecting the correct COM port.
- Connect the printer to the PC via USB cable, launch the print job, and monitor the progress.
Troubleshooting Common Printing Issues
- Gaps/hollows on the top layer: Insufficient layers, low fill value, or inadequate filament flow.
- Wire drawing: Inadequate withdrawal distance, withdrawal speed, excessive printing temperature, or poor tangential path.
- Printing model melting: Insufficient hot end cooling, excessive printing temperature, or high printing speed.
- Layer shifting/lost steps: High print speed, improperly installed belts/wheels, loose nuts/bolts, or faulty main board.
- Gaps between layers: Excessive layer thickness setting, low printing temperature, or temperature difference causing cracking (common for ABS).
- Grinding/worn-out filament: Increase printing temperature, reduce printing speed, or clean/replace the nozzle.
- Hot end clogged: Manually feed filament to check if it flows, or clean/replace the nozzle and nozzle throat.
- Not extruding during printing: Filament run out, filament grinding/slipping, clogged nozzle, overheating extrusion motor driver.
- Filling virtual filament: Adjust fill value, fill speed, or fill width in the slicing software.
- Surface stripes/bulges: Excessive printing temperature, misaligned Z-axis, suboptimal slice path settings, or extrusion instability.
- Rough angles: High printing temperature, poor hot end cooling.
- Path lines on the surface: Excessive filament extrusion, Z-axis uplift.
- Wrinkles on the surface: Poor filament quality, temperature fluctuations, bed shaking, or misaligned Z-axis.
- Vibration: High printing speed, whole-machine vibration, or incorrect firmware settings.
- Uneven extrusion: Feeding issues, hot end clog, inadequate layer thickness, incorrect extrusion width, poor filament quality, or extrusion force regulation issues.
- Motor shaking/abnormal sound: Obstacles or wiring issues preventing endstop triggering, loose motor connections, or cable routing problems.
- File not printing/SD card failure: Verify Gcode file readability, ensure SD card is readable, or replace a faulty SD card.
- Print stopped halfway: Corrupted Gcode file, faulty plugins in Gcode file, or switch to offline printing via SD card.
- Touch screen no response: Check for metal frame pressure, loose cables, or screen damage.
