Getting crisp, consistent results on every substrate starts with dialing in the right laser parameters. The ComMarker Omni 1—with its 5 W UV fiber laser—excels at high‑precision engraving and cutting across plastics, woods, metale, sticlă, piatră, and even organic materials. Below is an in‑depth, step‑by‑step reference to help you master material settings in LightBurn (or EZCad2) pentru 16 of the most common substrates.
📘 Why Proper Material Settings Matter
- Precizie & Contrast: lasere UV interact differently with each material. Too much power can scorch, too little leaves faint marks.
- Viteză & Throughput: Optimized speeds reduce cycle time without sacrificing quality.
- Longevity: Correct settings minimize wear on optics and prolong laser tube life.
- Siguranță: Proper passes and focus reduce fire risk and noxious fumes.
Before you begin, Întotdeauna:
- Clean Your Work Area – Remove debris and secure your material flat.
- Focus Carefully – Use the red‑dot preview and electric Z‑axis on the Omni 1 for pixel‑perfect focus.
- Ventilate – Run an exhaust fan or air purifier, especially on plastics, Piele, and organic substrates.
⚙️ Core Laser Parameters Explained
- Putere (%): Laser intensity (0–100%). Higher power means deeper cuts or darker marks.
- Viteză (mm/s): How fast the head moves. Faster speeds reduce burn but may lighten the mark.
- Frecvență (kHz): Pulse repetition rate. Higher frequency gives smoother edges on plastics and metals.
- Q‑Pulse Width: Pulse duration. Longer pulses (higher Q‑pulse) deposit more energy per pulse—useful for marking metal or leather.
- Passes: Number of times the laser follows the same path. Multiple shallow passes yield cleaner results on thick or reflective materials.
- Line Interval (mm): Spacing between raster lines. Smaller intervals increase resolution at the cost of time.
- Image Mode (LightBurn only): For grayscale or 2.5D effects (de ex., Atkinson dithering).
