Product Overview
- Provides information about the 3D printer.
- Includes a description of the printer's features and capabilities.
Menu Directory
- The menu directory provides information on the different menu options that can be accessed on the touchscreen of the 3D printer.
- These options provide access to features such as printing parameters, system settings, and print monitoring.
Assembly Instructions
- The assembly instructions provide step-by-step guidance on assembling the 3D printer.
- The instructions are accompanied by images, facilitating the assembly process.
- The instructions specify the components to be used, and how they should be assembled.
Filament Installation
- Only insert filament into the hotend after the printer has preheated.
- Cut off the bent tip of the filament before inserting it into the hotend.
- Rotate the filament if you feel any resistance during installation.
- Be sure that there is no tied or tangled filament on the reel.
Leveling Instructions
- Follow the Leveling Instructions carefully to ensure that the print bed is properly leveled.
- Proper leveling is crucial for achieving accurate and successful prints.
Slicing Software
- Make sure to use proper settings in the slicing software, such as the layer thickness, printing speed, and temperature.
- Incorrect settings can affect the quality of your prints.
Save GCode in Cura
- Make sure to re-open the Gcode file again in Cura to confirm that all slices of the model have been included by checking in the “Layers view."
- The file name should only contain English letters, underscore, and space.
Online Printing Instruction
- Use online printing for more convenient printing options.
- Ensure that the CH341SER driver is installed on the PC to enable online printing.
- Use a USB cable to connect the printer to the PC.
Offline Printing Instruction
- Print offline to avoid the need for a computer connection.
- Insert the SD card into the printer and print the desired gcode file.
- The machine will automatically heat up and start printing.
Change Filament Instruction
- When changing filament, make sure to use the correct type compatible with your printer.
- Feed filament through the filament sensor first.
- Cut off the bent tip before insertion for easier feeding.
Resume from Outage
- The printer supports resuming from a power outage only while printing offline.
- Ensure that the SD card is inserted and that the print job is saved.
- The machine will automatically resume printing once it has heated up.
Trouble shooting
- If you encounter issues with your 3D printer, refer to the troubleshooting section to identify and resolve the problem.
- The section covers a wide range of common issues, such as not extruding at the start, filament flowing insufficiency, layer shifting, and more.
- Each issue is accompanied by possible causes and solutions.
Laser Technology
- Lasers are becoming increasingly used in industrial machining because of their precision and quality.
- Laser-machined products have superior dimensional tolerances, accuracy, and minimal heat-affected zones.
- CNC capabilities are often integrated into laser-cutting machines for quality and timely outputs.
- The intensity of a laser beam can be varied to cut or engrave a variety of materials.
- CNC-controlled laser engraving does not require a resistive mask, the laser path and beam are precisely controlled by the CNC system.
Types of Laser Cutting Machines
- Three main types of lasers are used in laser cutting:
- CO2 lasers: Suitable for cutting, boring, and engraving.
- Nd lasers: Used for boring and applications requiring high energy, but low repetition.
- Nd:YAG lasers: Utilized when very high power is needed, for boring and engraving.
CO2 Lasers
- Since the discovery of lasers, CO2 lasers have been heavily employed in material processing.
- CO2 lasers emit radiation from an electric discharge within a gas mixture of carbon dioxide, nitrogen, and helium.
- CO2 lasers emit at a wavelength of 10.6 μm (infrared), with lower wavelengths used for processing certain polymers.
- CO2 lasers offer a high average power range, from a few Watts up to 50 kW.
- Commonly used in the automotive and steel manufacturing industries.
- CO2 lasers are ideal tools for industrial marking, annealing, engraving, and welding metals, plastics, and wood.
- CO2 lasers provide excellent beam quality but have lower electrical-to-optical conversion efficiency.
- Custom applications include greeting cards and limited edition products.
Future Scope of Laser Technology
- Integrating design software like SolidWorks to provide a GUI and automatically generate part programs from drafted profiles.
- Expanding the working area of laser cutting machines.
