xTool S1 Batch Engraving, Bed Size & CNC vs Laser: What I’ve Learned From Ordering for Our Shop

Quick Answers: What This FAQ Covers

If you're evaluating the xTool S1 for your shop or small business—especially for batch engraving, understanding bed size, or whether to go with a CNC laser vs. a traditional CNC router—you've got questions. I manage purchasing for a 15-person product development studio, and we brought in an xTool S1 in early 2024. Here's what I've learned (and where I've been burned).

1. Can the xTool S1 really do batch engraving efficiently?

Short answer: Yes, but there's a gotcha.

The xTool S1 supports batch engraving through its LightBurn software (or xTool Creative Space). You can set up an array of objects on the bed, and the machine will engrave them one by one or in sequence. The 20W and 40W modules make this fairly fast for small runs—think 20-50 keychains or coasters per session.

The gotcha? The S1 is a fixed-bed diode laser, not a gantry-style CO₂. For batch work with varying material thicknesses or warped pieces, you'll need to manually adjust focus for each piece (or use the automatic height sensor add-on). I wish I'd known that before we tried running 80 acrylic tags in one go. We had to stop and refocus 35 of them. (Not a disaster, but it ate up an afternoon.)

2. What’s the xTool S1 bed size? Does it matter for batch work?

The xTool S1 comes with a 400mm x 300mm (15.75" x 11.8") engraving area. That's standard for a desktop diode laser. For batch engraving, you can fit roughly 20-30 small items (like coasters or name tags) in one pass, depending on their size.

Here's my realistic take: If you're doing production-level batch engraving (hundreds of parts daily), the S1's bed size is a constraint. You'll be reloading frequently. For prototyping, small orders, or custom jobs, it's fine. We run batches of 30-50 parts per day and reload 2-3 times. That's doable but not automated.

If I had to do it over, I'd budget for the Extended Size Kit (adds 400x600mm capacity, as of January 2025). It's worth the $99 for batch work.

3. Can the xTool S1 cut metal? (The CNC laser cutting metal question)

Yes, but only thin metal with the 20W or 40W module. Diode lasers can engrave and cut stainless steel, mild steel, and brass up to about 0.5mm thick (for cutting). Engraving is fine on coated metals like anodized aluminum. But don't expect to cut 1/4" steel plate—that's a CO₂ or fiber laser's job.

We use our S1 for engraving metal nameplates and cutting brass shims for jigs. For actual metal fabrication, we still send out to a fiber laser shop. (I got burned once promising a client we could cut 2mm steel. Learned that lesson the hard way.)

4. What's the difference between a CNC and a laser cutter? Should I get a CNC laser or a CNC router?

"A laser is a hot knife; a CNC is a chisel." —A machinist friend of mine

Key differences:

• Laser cutters (like xTool S1) use focused light to melt/vaporize material. They're excellent for: cutting thin materials (up to 10mm acrylic, 3mm wood), engraving, and fine detail.
• CNC routers use spinning bits to physically remove material. They can: cut thick stock (up to 2" wood), 3D carve, and work with hardwoods, metal, and composite materials.
• Common misconception: A laser can't do 3D carves, and a CNC router can't do fine engraving without a special bit.

Which one for you? If you're doing mostly engraving, thin cuts, and detailed work—go laser (CNC laser, as in a laser cutter). If you need 3D carves, thick stock, or heavy fabrication—get a CNC router. Many shops have both.

In our studio, we use the xTool S1 for prototyping, engraving, and thin sheet cuts, and a Shapeoko CNC router for thicker wood parts and 3D carves. They complement each other well.

5. What are some practical CNC laser projects I can start with?

These are the projects we've actually done (and made money from):

• Custom nameplates for equipment and office signs (coated brass, acrylic)
• Batch-engraved keychains for corporate gifts (20-50 per run)
• Thin acrylic enclosures for electronics prototypes
• Leather tags for a local craft brewery (customers love them)
• Stencils for spray painting (use kraft paper or thin cardboard)
• Test cuts before committing to expensive material (we do this every time)

Pro tip: Always run a test cut on a scrap piece first. I learned this after ruining a $40 sheet of acrylic because I guessed the speed/power settings. (That was in January 2024. I remember the exact date because my boss was not pleased.)

6. Is batch engraving with xTool S1 ideal for time-sensitive orders?

Here's where my time-certainty bias (or as I call it, the "sure thing premium") kicks in. If you have a deadline—say, 200 custom pieces for a trade show in 3 days—a diode laser batch run is not your sure thing. You'll fight focus issues, material variability, and the occasional software hiccup. For time-sensitive work, I'd either:

• Outsource to a fiber laser shop (they batch hundreds per hour)
• Use a CO₂ laser (more stable for batch work)
• Or at least double your buffer time (plan for 2x the estimated runtime)

We paid $400 for rush outsourcing in March 2024 to meet a deadline. The alternative was missing a $15,000 order. That $400 was a bargain.

7. What's a common mistake people make when comparing CNC vs laser?

Thinking they're interchangeable. They're not. A laser cuts with heat; a CNC router cuts with shear forces. That difference matters for:

• Edge quality: Laser leaves a slightly charred edge on wood; CNC leaves a clean cut (but may have bit marks).
• Material thickness: Laser struggles with thick stock; CNC handles it easily.
• Detail: Laser engraves finer details than most CNC bits can achieve.

I don't have hard data on industry-wide preferences, but based on our experience, most small businesses with prototyping needs start with one and add the other later. We started with the CNC router, then added the xTool S1 for engraving. That sequence worked well for us.

Final thought: The xTool S1 is a capable machine for its price point ($599-$1,299 as of January 2025, depending on module). For batch engraving, it's good for small runs. For CNC laser projects, start simple. And if you're on a deadline, pay for certainty.
