2. Material Loading:
Place your material securely on either the honeycomb or aluminum blade bed. For mirror acrylic, load the material with the backside facing up for engraving. Use magnets or clampചലനം തടയാൻ എസ്.
3. പാരാമീറ്ററുകൾ ക്രമീകരിക്കുക:
Adjust laser power, speed, and other settings in your software according to the material type and desired effect (engraving or cutting). Refer to material test guides for recommended settings.
4. Starting the Job:
Initiate the laser job from your software or the machine's control panel. Monitor the process through the flame-retardant viewing window. The machine will automatically pause if the lid is opened.
