Laser Engraving Layers: Help & FAQ | Laser Layer Maker
Find answers about image preparation, materials, background removal, clusters and downloadable laser engraving files in the Laser Layer Maker FAQ.
What material should I pick first if I'm brand new?
Start with aluminum or steel. They're forgiving, cheap in card-blank form, and the F2 Ultra is genuinely happy on both.
What's the difference between the six materials in the picker?
| Material | Burn style | Typical use |
|---|---|---|
| Polymer | Non-overlap (one shot per spot) | PMAG mags, polymer badges, plastic tags |
| Coated metal | Additive | Painted/lacquered metal cards, coated tags |
| Anodized aluminum | Additive | Anodized card blanks, aluminum tumblers, name plates |
| Wood / MDF | Non-overlap | Ply, MDF, hardwood plaques |
| Leather | Non-overlap | Wallets, patches, coasters |
| Stainless steel | Color-mapped (annealing) | Steel cards, food-grade blanks, tumblers where color matters |
Why does the app ask me to pick a material before processing?
Because the material dictates how the layers should be separated. It's not a label — it's an input to the segmentation.
My material isn't in the list — what do I do?
Pick the closest cousin from the five options, then dial in with test cuts on scrap.
Can I use the same layer file on different materials?
The vector geometry, yes. The power settings, no.
Why does my material look muddy / burned / faint?
Usually one of three things — wrong material selected, too many clusters, or suggested power taken as gospel instead of a starting point.
Which background removal option should I use?
- Remove outside white background — finished illustrations on a near-white surround. Removes only qualifying areas connected to an image edge; preview and adjust tolerance first.
- Auto — AI subject removal for photographs and complex subjects.
- Auto (cartoon) — AI removal for illustrations. It can still remove parts of a composition, including paws or decorative artwork; inspect the result.
- Fast — try for a clear subject on a simple background.
- Keep image as-is — skip automatic removal and preserve an existing transparent background.
When should I use "Auto (cartoon)" instead of regular Auto?
Try Cartoon for illustrations, but inspect what it removes. It can still cut away artwork. For a finished design on a white surround, try Remove outside white background instead.
When should I skip background removal entirely?
When you pre-processed the image yourself, or when the background is *part* of the composition.
The background removal chewed up my subject's hair or edges. Now what?
Try the other mode first. If both fail, remove the background yourself and re-upload with "Keep background."
Can I remove the background myself before uploading?
Absolutely — and for high-stakes engravings, we recommend it.
Why does the "BG removed" preview show a checkered pattern?
That's the industry-standard way to display transparency. The checkerboard *is* your background — meaning it was correctly removed.
What is a "cluster" or "layer" and how do I decide how many?
A layer is one band of similar gray values, extracted from your image as its own engravable region. Start with 4. Adjust from there.
Why does the app recommend 4–5 for polymer, wood, and leather?
Because those are non-overlap materials — each spot gets burned once, so extra layers steal detail rather than add it.
When would I use 6, 7, or 8 clusters?
On additive materials (coated metal, anodized aluminum) with images that have genuine tonal richness — portraits, landscapes, detailed illustrations.
My face/eyes/fine detail disappeared. What happened?
You probably over-clustered. Drop to 4 and re-run.
Do more clusters always mean better quality?
No — often the opposite.
How do clusters map to depth in the final engraving?
Darker cluster = deeper burn = higher power (or more passes). The app pre-maps this for you on the layer cards.
I see three download options — which one do I use?
- Open in xTool Studio (.xs) — you use xTool Studio. Easiest path.
- Download composite SVG (all layers) — you use xTool Studio and prefer the Color Engrave workflow.
- Download full bundle (.zip) — you use LightBurn, or you want every file the app produced.
What's the difference between the .xs file and the composite SVG?
The .xs is a full xTool Studio project with power settings pre-mapped. The composite SVG is one flat file for the manual Color Engrave workflow.
I use LightBurn, not xTool Studio. What do I download?
Download full bundle (.zip). LightBurn imports the per-layer SVGs (or DXFs) as separate process layers.
What are the "Segmented", "Gray map", and "BG removed" previews for? Can I download them?
They're diagnostic previews so you can sanity-check the job before running it on your laser. Yes, all three (plus the original) are included in the full bundle .zip.
The layer files opened but the settings look wrong. What now?
The .xs carries settings; the SVG and DXF don't. If you're in LightBurn, you're expected to set power/speed/passes yourself — the suggested values are on each layer card in the app.
Can I re-import my downloads back into Laser Layer Maker to tweak them?
Not currently. If you want different clusters or background removal, re-run the job from the original upload.
What am I looking at on each layer card?
A gray-value banner on top, a suggested power for your material, three view toggles (Color / Mask / Gray), a thumbnail, the layer's share of the image, and per-layer download buttons.
Color / Mask / Gray — what does each view show, and does switching change what I download?
They're three ways to *look* at the same layer. Switching views changes nothing about what you download or engrave — pure display.
What does the G### number in the corner mean?
The layer's mean gray value on a 0–255 scale. Higher = darker = deeper burn.
How is the "Suggested power %" calculated, and how much should I trust it?
Gray value scaled into a power range appropriate for your selected material. Trust it as a starting point — always test on scrap.
Why does the suggested power change when I switch materials?
Different materials need vastly different power to reach the same visual depth. The app rescales suggestions to match.
What does "X% of image" mean, and why does it matter?
How much of your composed image this layer covers. Helps you gut-check whether the cluster split makes sense.
When would I download an individual layer's SVG or DXF instead of the full bundle?
When you only want one layer — for hand-tweaking in Illustrator, for a single-pass engraving test, or for combining layers from multiple jobs.
