Setup guides, troubleshooting, and answers to common questions.
From unboxing to your first engraving in four steps.
Remove the machine, power adapter, and USB cable. Verify the protective lens cover is removed. Check for the factory test sample inside the packaging.

Power on the machine. Connect via Bluetooth or Wi-Fi. Place your material on a flat surface. Use the built-in auto-focus or manual height adjustment to set focal distance.
Select a preset material profile in the app. Import your image or text. Tap Start. Your first engraving finishes in under a minute on most materials.
Recommended starting parameters for common materials. Fine-tune power and speed based on your specific material batch.
| Material | Model | Power (%) | Speed (%) | Passes | Notes |
|---|---|---|---|---|---|
| Basswood (3mm) | LP2 / LP5 | 80-100 | 60-80 | 1 | Light engrave. Reduce power for thinner stock. |
| Plywood (3mm) | LP2 / LP5 | 100 | 40-60 | 2-3 | Cut through requires multiple passes. Check adhesive type. |
| Leather (vegetable tanned) | LP2 / LP5 | 40-60 | 80-100 | 1 | Test on scrap first. Avoid chrome-tanned leather (toxic fumes). |
| Acrylic (cast, 3mm) | LP5 | 100 | 30-50 | 3-5 | Produces frosted engrave. Remove protective film before cutting. |
| Anodized Aluminum | LP2 / LP5 | 60-80 | 90-100 | 1 | Removes anodized layer to expose metal beneath. Clean surface first. |
| Stainless Steel | LP4 / LP5 (IR) | 80-100 | 50-70 | 1-2 | IR module required. Creates dark oxide mark. Results vary by alloy grade. |
| Titanium | LP4 / LP5 (IR) | 60-80 | 60-80 | 1 | Color marking possible by adjusting power/speed ratio. Test on sample first. |
| Cork | LP2 / LP5 | 30-50 | 90-100 | 1 | Low power prevents burn-through. Keep speed high. |
These are starting points. Actual results depend on material batch, thickness, ambient temperature, and surface finish. Always run a small test area first.
Common issues and how to fix them.
Diode lasers (LP2, LP5 diode module) cannot directly mark bare metal. They work on anodized, painted, or coated metal surfaces only. For bare stainless steel, titanium, brass, or gold, you need the IR fiber module available on the LP4 and LP5.
If you have the IR module and marks still do not appear:
Smoke is normal during laser engraving, especially on wood, leather, and acrylic. Excessive buildup causes two problems: reduced engraving quality and potential fire risk on flammable materials.
Firmware updates occasionally reset custom material presets. Export your presets before updating (Settings > Material Presets > Export).
The LaserPecker Design Space app accepts the following formats:
For best results with photo engraving, use high-contrast PNG files at 300 DPI or higher. The app includes grayscale conversion and dithering options for photographs.
Always wear the included laser safety goggles when operating any LaserPecker machine in open-frame mode. The LP3 and LP4 enclosed designs provide Class 1 safety during normal operation, but goggles are still required when the enclosure is open for maintenance or alignment.
Laser engraving produces smoke and particulates. Always operate in a ventilated space or use an exhaust/filtration system. Never engrave PVC, vinyl, or materials containing chlorine compounds. These release toxic hydrochloric acid gas when heated.
Keep a fire extinguisher or fire blanket within reach. Never leave the machine unattended during operation. Remove flammable materials from the work area. The machine has a built-in thermal sensor that pauses operation if the housing temperature exceeds safe limits.
Do not engrave or cut: PVC, vinyl, ABS, polycarbonate, HDPE, fiberglass, carbon fiber, or any material you cannot positively identify. When uncertain, check the material safety data sheet (MSDS) for decomposition products before processing.
