Why This Guide

Complex artwork—fine filigree, tiny text, dense textures—pushes materials and machines to their limits. This guide gives you a repeatable, cross‑material process you can copy with the TOOCAA L2 Desktop Laser Engraver & Cutter, plus starter settings and troubleshooting so you ship consistent results.

 

The “Complex Design” Checklist

Minimum Feature Size & Line Weight

Your smallest reliable line is governed by laser spot size and the materia. On L2 modules, the typical optical spot is about 0.08 × 0.18 mm (10W) or 0.15 × 0.27 mm (20W). As a rule of thumb, set minimum line width ≈ 2× spot size and test on scrap before production.

Artwork Format: Vector First

For logos, icons, and line art, use SVG, AI, or DXF formats and ensure all strokes are expanded to your target line width.. For photos or textures, export a high-resolution PNG and use dithering in your CAM software such as LightBurn to map tones into burnable dots.

Contrast Planning

Complex designs succeed when the substrate’s response curve—such as charring, frosting, color lifting, or marking—produces clear contrast. For example: anodized aluminum removes dye to reveal bright metal; slate turns lighter; glass frosts; leather darkens. Plan your fills and line spacing to exploit that contrast, then confirm with a small power-speed test grid.

A Repeatable 4‑Step Workflow

Prepare the Artwork 

Vector line art: expand strokes to ≥2× spot size; avoid hairlines.

Photos/textures: choose a dithering algorithm and test line interval (e.g., 0.08–0.12 mm on wood).

Export: SVG/AI/DXF for vector; high-res PNG for raster.

Run a Test Grid 

On a matching piece of scrap material, engrave a small test grid that varies the power (P%) and speed (mm/min), as well as the line interval if you are engraving filled areas. Record the settings from the best-performing cell and save them as a "parameter card" for that specific material.

Fixture, Focus, Air

Ensure the workpiece surface is perfectly flat using a honeycomb bed secured with magnets, tape, or soft clamps. Then, dial in the precise laser focus and enable Air Assist to clear smoke and cool heat-sensitive materials like acrylics and rubbers.

Engrave Light, Iterate Smart

Begin with lighter power and faster speed settings. Only add more passes or reduce the speed if the results require it. After each test, inspect the edge quality for crispness versus any halo effect, evaluate the contrast to ensure it is punchy rather than washed out, and examine the surface condition for any signs of charring or melting. Refine your settings through iteration before proceeding with the full-scale job.

Material‑Specific Playbooks

These are starting points from TOOCAA’s official Material Settings tables for L210W and L2-20W. Always run a test grid—color, finish and batch differences can require adjustment.

Wood(hardwoods, plywood, bamboo)

Goal: crisp lines without over-char; stable photo dithers.

Starters: L2-10W (engrave): Basswood 40% / 3000 mm/min / 1 pass.

L2-20W (engrave): Birch 80% / 24,000 mm/min / 1; Maple 40% / 24,000 mm/min / 1.

Pro tips: Prefer tight-grain hardwoods (maple, cherry) for micro-detail; apply masking to reduce smoke staining; sand & seal if you need high contrast.

Metals: (Anodized/painted/powder‑coated vs bare with marking spray.）

 
Mechanisms:Coated/ANO metals: laser removes coating/dye, revealing bright substrate (high contrast).

Bare stainless/aluminum: use a marking spray/paste to fuse pigment into the surface (marking rather than deep ablation).

Starters: L2-10W: Anodized aluminum 100% / 200 mm/min / 1; Stainless steel 100% / 500 mm/min / 1.

L2-20W: Aluminum 100% / 6000 mm/min / 1; Stainless steel 100% / 3000 mm/min / 1. TOOCAA

Detail tips: Ensure thin, even coatings; for filled areas, try tight line intervals (e.g., 0.05–0.10 mm); log your best combo per color/coating.

Glass & Ceramics

Approach: low power, higher resolution, avoid long dwell; masking tape can tame microchips.

Starter (L2-10W): White tile (painted black) 95% / 3800 mm/min / 1.

Stone(slate, granite, marble)

Approach: slower movement, higher power; multiple shallow passes; slate & granite offer strong contrast. Test polish/porosity before finals.

Acrylic & Plastics

Approach: cast acrylic engraves frosty/clean; blends and soft plastics heat easily—keep Air Assist on and scan fast.

Starters:

L2-10W (engrave): Black acrylic 4.5 mm 50% / 3000 mm/min / 1.

L2-10W (cut): Black acrylic 4.5 mm 100% / 120 mm/min / 2.

L2-20W (engrave): Black acrylic 2.6 mm 60% / 21,000 mm/min / 1.

L2-20W (cut): Black acrylic 100% / 200 mm/min / 1.

Leather

Approach: low power / high speed to avoid harsh burn; vegtan usually engraves cleaner than chrometan.

Starters:

L2-10W: Brown leather ~0.65 mm 20% / 3000 mm/min / 1.

L2-20W: Leather (various colors) 60–100% / 16,500–24,000 mm/min / 1, color-dependent.

Pro tips: Mask with painter’s tape for cleaner surfaces; wipe residue after engraving.

Rubber & Silicone(soft elastomers)

Approach: heat-sensitive—engrave shallow & fast with strong ventilation + Air Assist; expect shallow, readable marks more than deep relief.

Caution: Never process PVC/vinyl or unknown plastics (toxic, corrosive fumes).

Fixtures, Focus & Repeatability

Jigs > chance: Use a honeycomb panel and simple jigs for tumblers, tags and cards so you can place pieces identically every time.

Focus = detail: Slight defocus blurs micro-lines—always check focus after height changes.

Parameter cards: Log winning P/S/interval/pass combos by material → color/finish → thickness to speed future jobs.

Safety Essentials

L2 is designed for Class 1 enclosed operation, but the laser emitter itself is hazardous if exposed—never defeat the enclosure or interlocks.

Provide active ventilation (or a smoke purifier) and never leave jobs unattended—especially vector cuts and acrylic.

Do not engrave PVC/vinyl or unidentified plastics; chlorine-bearing fumes are dangerous and can destroy equipment

Troubleshooting for Fine Details

Edges Look Fuzzy

Refocus; clean lens; ensure the workpiece is flat and well-clamped. Reduce speed slightly or increase line interval for filled areas.

Contrast Is Too Low on Coated Metal

Slow down or add a second pass. Ensure coatings (paint/powder) are thin and even; keep line intervals tight for filled regions.

 

Plastics Melt or Curl

Lower power, increase speed, enable Air Assist, and use multiple light passes. Consider pausing between passes to let heat dissipate.

 

Smoke Staining on Wood

Mask the surface, improve Air Assist, and lightly sand or seal after engraving.

FAQs

What’s the L2’s working area and speed?

415 × 395 mm working area and maximum engraving speed 400 mm/s (module-agnostic).

Which software is supported?

TOOCAA Studio, LightBurn, LaserGRBL on Windows/macOS, with transfer via TF card or Type-C.

Which materials are supported?

Woods, coated/ANO metals, dark glass, slate/stone, ceramics, leather/fabrics, cardboard, plastics, and dark acrylic (except blue)—always test your exact stock.
