xTool S1 20W performance on fabric

The xTool S1 20W supports cutting and engraving fabric. Recommended cut speed is 600 mm/min (~10 mm/s) across the thicknesses in the tables below. Engraving runs at up to 5000 mm/min (~83 mm/s). Its 600×400mm work area and 20W diode source set the practical limits for project size and material thickness.

The xTool S1 20W is a 20W diode laser with a 600×400mm work area. At 20W, this is a mid-power diode that cuts most hobby materials in one to three passes while still engraving with fine detail. Fabric cutting with a laser seals edges to prevent fraying, giving a cleaner finish than scissors or rotary cutters. Below you will find tested starting parameters for cutting and engraving fabric on this machine.

Safety Note: Only cut natural fabrics (cotton, linen, denim). Synthetic fabrics like polyester melt and can produce toxic fumes. Always test a swatch first.

How to Set Up Fabric on the xTool S1 20W

  1. 1Secure your fabric flat on the work bed using clamps, magnets, or a honeycomb pin set to prevent movement during the job.
  2. 2Set your focus distance accurately — use the auto-focus probe if your machine has one, or measure manually with the focus gauge.
  3. 3Keep a fire extinguisher or spray bottle nearby. Fabric is flammable — never leave the machine unattended while cutting this material.
  4. 4Enable air assist if available. A steady stream of air at the cut point removes debris, reduces charring, and helps prevent flare-ups.
  5. 5Enter the speed, power, and pass count from the settings table above into LightBurn. The table lists both mm/min and mm/s — LightBurn defaults to mm/s, so use the mm/s value unless you have switched units. Use the “Cut” or “Engrave” layer settings panel.
  6. 6Run a small test cut or engrave on a scrap piece of fabric before committing to your final project piece. Adjust power up or down by 5–10% based on results.

What to Expect When Lasering Fabric

Laser-cut fabric edges are sealed by the heat, preventing fraying — this is one of the biggest advantages of laser cutting textiles. Expect slight darkening or browning on cut edges depending on the fabric type and color. Engraving creates a visible surface texture change or color shift. Synthetic fabrics may melt slightly at the edges. The 20W output clears the majority of common materials in one to three passes, giving a good balance of speed and detail. Dense hardwoods and thick acrylic still benefit from a slower finishing pass.

Common Mistakes to Avoid

  • Running at full power on the first attempt — always start with a test piece at the recommended settings and adjust incrementally. Going straight to maximum power risks burning through the material or causing fire.
  • Using the slow speeds you would need on a 5–10W machine — a 20W diode runs noticeably faster, and going too slow at this power causes excess charring and a wider kerf.
  • Leaving the machine unattended — lightweight fabrics are flammable and can ignite if the laser pauses or settings are too high.
  • Not weighing down or pinning the fabric flat — fabric that is not perfectly flat will produce uneven cuts and may shift during the job.

Tips for Fabric on Laser Machines

  • Pin or tape fabric taut to the bed to prevent movement and wrinkling.
  • Natural fibers (cotton, linen) cut cleanly while synthetics tend to melt.
  • Use low power and higher speed for delicate fabrics to avoid burning.
  • A honeycomb bed works best for fabric to allow airflow underneath.
  • Denim and canvas are the easiest fabrics to laser cut consistently.

Frequently Asked Questions

What speed and power should I use for fabric on the xTool S1 20W?
For 1mm fabric, start with 600 mm/min (~10 mm/s) at 40% power with 1 pass. Always test on scrap material first and adjust based on your specific conditions.
