User Manual for Elegoo Phecda Laser Engraver and Cutter

Quick guide from the manual

The Elegoo Phecda laser engraver is a powerful tool that requires strict adherence to safety protocols. Always wear laser goggles when the machine is in operation and ensure no pets or unauthorized persons are nearby. The device operates using .nc files stored in the root directory of a TF card. Before starting any project, ensure the laser focus is correctly set using the provided kickstand and that the Home position is defined to prevent the laser module from colliding with the frame.

Device overview and setup

The machine features a touch screen interface for control. On the side of the machine, you will find the AC/DC power connection, USB port, TF card slot, and the main power switch. Always ensure the power is OFF before inserting or removing the TF card. To set the laser focus, remove the orange cover plate, loosen the set screws, rotate the black plastic kickstand to the downward position, lower the laser module until the kickstand rests on the workpiece, and then tighten the set screws.

Operating the laser

The Home screen provides access to four main functions: Adjustment, Control, Carving, and Tool. Use the Adjustment screen to project a low-power beam to locate the carving area. The Carving screen allows you to select .nc files from the TF card. You can choose between Plane Mode (for flat surfaces) and Rotation Mode (for cylindrical objects). Use the directional buttons to jog the laser module and set the Home position. The Mark the Perimeter feature is essential for verifying the carving area before starting the job.

Screen navigation

The interface is divided into specific screens for different tasks. The Control screen is used for moving the laser and setting the origin. The Tool screen provides access to system information, WiFi settings, language selection, fire detection sensitivity, and tilt detection settings. During carving, the screen displays progress, and you can pause to adjust power and speed settings in real-time.

Maintenance and safety

Regular maintenance is crucial for the longevity of the machine. Inspect and clean the laser module's cooling fans, the dust collection turbo fan, and the window mirror regularly. Debris buildup on the window mirror can cause it to overheat and crack. If the machine is used in direct sunlight, the flame detection sensor may trigger; you may need to adjust its sensitivity or turn it off, but always monitor the machine closely when doing so.

Laser settings reference

The manual provides detailed tables for suggested laser settings, including power percentage and speed (mm/min), for both the 10W and 20W versions of the Phecda. These settings vary based on the material type (e.g., wood, leather, metal) and the operation (engraving vs. cutting). Always refer to these tables as a baseline for your projects.
