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.
