Like every other process, laser engraving and laser cutting depends on the material you are using. Even if the Xtool Studio software have alot of predefined settings that you can use on scorching, engraving or cutting, it does not guaranty a perfect results.
Material variation
Materials are far from uniform. Whether you buy from online suppliers, local home improvement stores, or specialty laser material vendors, you’ll encounter variations from supplier to supplier and even batch to batch.
Plywood thickness can vary by several tenths of a millimeter. Moisture content changes with humidity and storage conditions, affecting how the laser interacts with the wood. MDF, acrylic (cast vs. extruded), leather, and other popular materials all behave differently. A batch of “3mm birch plywood” from one supplier might cut beautifully at certain settings, while another batch requires noticeably more power or slower speeds.
Sticking with the same trusted supplier reduces risk, but it doesn’t eliminate it entirely. Seasonal changes, manufacturing tolerances, and slight differences in composition mean your results can shift over time. This is especially true for natural materials like wood, where grain density and resin content play a big role.
That’s why relying solely on XTool’s built-in presets or settings from a previous project often leads to disappointment. A quick test bridges the gap between “theoretical” and “actual” performance.
Test run
Before making the final product on the S1, make sure you do a test part. I mean by whis using the templates from the Xtool studio to make a test for the scorching, engraving and or the cutting. Personaly, when I get some new maeterial, I alsways to a test. I have noticed that the material can change the results of the process and you might need to adjust your settings to insure the part comes out the way you were expeting it.
Choosing the Right Settings: Quality + Efficiency
Let’s use wood cutting as the main example — the same principles apply to engraving and other materials.
When you run the cut test grid, some squares will cut through while others won’t. Among the successful ones, you’ll see wide variation in power and speed, especially on thinner stock.
My rule of thumb: Choose the highest practical speed with sufficient power for a clean cut.
Why prioritize higher speed?
- Higher power settings (when the machine is well-maintained) have minimal impact on the diode laser’s lifespan.
- Lower speeds add significant machine time over hundreds of projects. Going from 6 mm/s to 4 mm/s might not seem like much on one piece, but it compounds and reduces overall productivity.
Quality is equally important
High power and very low speed do not equal better results — often the opposite. Slow passes can cause excessive charring, wider kerf, or burning on the back side.
Pro inspection tip: After the test, flip the material over. On thicker stock, slow settings frequently leave burn marks or residue on the reverse side. Look for clean cuts on both faces with minimal darkening. Choose settings with a small safety margin rather than ones barely cutting through at 100% power. Small material variations can then cause incomplete cuts on your final project.
For engraving, test different lines-per-cm settings and power levels. Evaluate contrast, depth, and surface smoothness. On leather or acrylic, test multiple passes versus single high-power passes.
Remember: the goal is repeatable, clean results — not just “it finally cut through.”
Maintenance
Make sure to perfrom the recommended maintenance. It might sound strange to some people that I say this but the lense of the laser might get dirty and you end up with lower power being transported to the part cut, giving you poor results.
The Real Cost of Skipping Tests
Skipping tests might save a few minutes upfront, but it often leads to wasted material, ruined projects, and lost time. A single spoiled sheet of premium plywood or acrylic can cost $20–$100. For small business users fulfilling orders, failed runs mean missed deadlines and unhappy customers.
Multiply that across dozens of projects, and the financial and emotional cost adds up fast. Testing is cheap insurance for consistent quality and better profitability.
Advanced Tips for Long-Term Success
- Build your material library — After successful tests, save custom settings in XTool Studio for quick reuse.
- Document everything — Note the exact material type, batch, humidity conditions, and settings that worked best.
- Use supporting accessories — The honeycomb bed prevents back burns. Proper air assist clears debris and reduces charring. Adjust focus offset when needed.
- Re-test when conditions change — New supplier, seasonal humidity shifts, or after major maintenance all warrant fresh tests.
- Safety first — Always monitor tests, especially aggressive parameters. Have a fire extinguisher nearby and never leave the machine running unattended.
Conclusion
Making multiple failed attempts because settings were wrong is never fun. It wastes material, time, and energy — resources we’d all rather spend creating great projects.
By taking a few minutes to run a material test whenever you have a new batch or change suppliers, you’ll dramatically improve consistency and efficiency on your XTool S1. The habit pays for itself many times over.
I speak from experience: that small investment in testing has saved me countless hours and dollars. Your projects will look more professional, your workflow will flow smoother, and you’ll enjoy the laser crafting process much more.
