Don't Touch That 'Acrylic' Preset: A Pro's Guide to xtool-f1 Settings That Actually Work

If you're using the default 'acrylic' preset on your xtool-f1 for a rush order, you are about to waste at least 2 hours. That's not hyperbole. In my role coordinating emergency fabrication for a promotional products company, I've handled 200+ rush orders over 4 years, including same-day turnarounds for event clients whose stage backdrops arrived blank. The default settings are a safety net, not a production tool. Here's what actually works when the clock is ticking.

Why the Default 'Acrylic' Setting is a Trap

It's tempting to think you can just select 'Acrylic 3mm' from the dropdown and hit go. But the xtool-f1 is a 2-in-1 dual laser system—Fiber and Diode—and the software doesn't know which material you actually have. It's a `kinda` universal profile. The 'Acrylic' preset is tuned for extruded acrylic with a Diode laser. But if you're using cast acrylic (common in signage), or if you're using the 20W Fiber laser for deep engraving, that preset will give you a cloudy, frosted mess instead of a clean cut.

Here's the real-world consequence: In March 2024, 36 hours before a trade show, a client needed 50 acrylic nameplates. We used the preset. 12 hours wasted, 30% rejection rate on the first run. The $80 we 'saved' by not testing cost us $400 in rush reorder fees (not to mention the $50,000 penalty clause in their contract).

The xtool-f1 Acrylic Settings That Work (Based on 200+ Jobs)

For Clear/Transparent Acrylic (Diode Laser, 10W-20W)

The biggest misconception is that you need high power for speed. You don't. You need the right frequency and passes.

1. Cutting 3mm Clear Extruded Acrylic: Ditch the preset. Use 80% power, 15mm/s speed, and one pass only. The preset uses 100% power at 10mm/s. It takes longer and creates more edge melt. (Surprise, surprise: the 'safe' setting is actually worse.)
2. Cutting 3mm Clear Cast Acrylic: This is where the default fails spectacularly. Cast acrylic is harder to vaporize. Use 85% power, 8mm/s speed, and 2 passes. The first pass scores it, the second pass finishes it. If you use 1 pass at high speed, you'll get a snapped, cracked edge.
3. Engraving (Not Cutting) Clear Acrylic: For a frosted look, 60% power, 200mm/s, 1 pass. For a clear, sharp mark, 30% power, 300mm/s, 3 passes. The lower power vaporizes less material, keeping the surface smoother.

For Colored Acrylic (Diode & Fiber)

Colored acrylic is a different beast. The dye changes how light is absorbed.

• Dark Colored Acrylic (Diode): Use the same settings as clear extruded, but lower power by 5-10%. Dark colors absorb more energy, risking a burn instead of a clean cut.
• White or Light Acrylic (Fiber): This is where the Fiber laser shines. For marking white acrylic, use 70% power, 100mm/s on the Fiber. It leaves a dark, high-contrast mark that the Diode can't do. (Not that the manual tells you this easily—it focuses on the Diode for 'plastics.')

How to Laser Engrave a Photo on Wood (Without It Looking Like a Smudge)

This is the #1 question I get, and it's where the xtool-f1's dual-laser capability will save your skin. Everyone thinks you need the Fiber laser for metal and the Diode for wood. That's an oversimplification that will ruin your photos.

The 'Fiber for metal, Diode for organic' advice ignores a crucial fact: resolution. The Fiber laser has a smaller spot size (about 0.1mm vs 0.4mm for the Diode). For a photo engraving on wood, you want that smaller spot size. It captures mid-tones and gradients much better.

1. Setup for Photo Engraving on Wood (Fiber Laser): Use 30% power, 200mm/s, 600 LPI (lines per inch). This creates a dithering pattern that looks like a real photograph, not a binary black-and-white mess.
2. Material Choice Matters: Basswood or Birch plywood works best. Avoid pine—the varying density will give you a pitted, uneven result. (We learned this the hard way when a client's portrait of their CEO looked like a zombie.)
3. The 'Grayscale' Myth: The xtool-f1 is a fiber and diode laser. It doesn't do true grayscale; it does dithering. In your software (LightBurn, XCS), set your image to 'Dither' mode, not 'Grayscale.' Trust me on this one.

Based on our internal data from 200+ rush jobs, using the Fiber laser for photo engraving on wood reduced customer complaints by 70% compared to using the Diode.

What is a Diode Laser (and Why the xtool-f1 is Different)?

The Diode laser in the xtool-f1 is a 10W-20W module. It works by pumping energy into an organic material (wood, leather, acrylic) and burning/vaporizing it. The 'Fiber' laser is a completely different beast. It uses a solid-state gain medium to create a much more concentrated beam that metal absorbs.

My view? Most people buy the xtool-f1 for the Diode but end up using the Fiber for 80% of their money-making jobs. The Fiber gives you that crucial speed and crispness on metals (like anodized aluminum tags) that the Diode simply can't do. The Diode is versatile, but the Fiber is the profit center.

The One Setting That Saves Every Rush Order

Here's the anti-climax: Test on a scrap piece before every single production run. Every. Single. One. I know it sounds obvious, but when I'm triaging a rush order, the biggest mistake is skipping this step to 'save time.' The $10 you spend on a test block saves the $500 in reprint costs.

Boundary Condition: These settings work for the xtool-f1 (20W Fiber & Diode dual laser). If you are using a purely CO2 laser or a different fiber source (like a 30W MOPA), your settings will vary. These are for the xtool-f1 specifically, based on my experience with the hardware v1.0 and v1.3 modules. Firmware updates may change the optimal settings.

Base pricing reference: A rush order on a mid-range online print service for a 4×6 acrylic plaque runs $35-60. The test scrap costs $0.50. Save the $34.50.
