TL;DR

The 40W S1 is xTool's high-power enclosed diode. Still not CO₂, but the extra optical power helps on thicker basswood versus the 20W cabinet.

What makes this machine stand out

Hardware and workflow features worth understanding before you buy : not just wattage on a label.

  • Swappable laser module

    You can upgrade optical power (or add an infrared module on some lines) by swapping the laser head on the same chassis : not buying a whole new machine. Check connector compatibility and firmware before assuming your future 40W module fits today’s 10W purchase.

  • Open-frame : plan safety first

    There is no factory enclosure: you wear OD-rated glasses, control smoke, and keep kids/pets away. You trade cabinet convenience for price and access : fine in a dedicated workshop, stressful in a living room without a plan.

  • LightBurn compatible

    LightBurn support means advanced layers, camera tools, and workflows many makers outgrow the stock app with. Confirm your exact controller board before assuming full features : some machines need a paid license separately.

  • Galvo speed class

    Galvo mirrors move the beam instead of a heavy gantry : engraving speeds that feel instant on small fields. Trade-off: tiny work area versus a flatbed diode; ideal for jewelry, tags, and batch marking, not large signs.

Our verdict

Ideal if you

The 40W diode module is the most cut-focused head on xTool S1: thicker basswood and faster fills than entry modules on the same chassis.

Skip if you

Overkill if you only do fine engraving. Still a diode: clear cast acrylic means CO₂. Plan glasses and exhaust if the chassis is open-frame.

Pros

  • Strongest cut headroom in the line: about 10 mm basswood-class stock in benchmarks
  • Swappable head on the same chassis: upgrade power without replacing the whole machine
  • Integrated cabinet helps contain the beam and everyday smoke versus open-frame diodes

Cons

  • Clear cast acrylic and thick production cutting still favor CO₂, not diode power alone
  • Confirm optical wattage on the listing before you buy

Practical notes

Beginner notes

This profile is the 40W SKU on xTool S1. Read the TL;DR and benchmarks above, then compare other modules via the chips before buying.

Pro tips

Treat engraving and cutting as separate profiles. Push cut speeds only after test squares on your material. Compare CO₂ only when clear acrylic or all-day production enters the picture.

Common questions

Is the xTool S1 safer than an open-frame laser?

Yes. The enclosure blocks direct beam exposure and contains smoke. You still follow safety rules, but accidental exposure risk is much lower than open-frame diodes.

Can the S1 replace a CO₂ laser?

No. It is still a diode laser with the same acrylic and cutting limits. Buy CO₂ (like xTool P2) if clear acrylic and thick wood cutting are your main work.

Alternatives to the xTool S1 40W

Machines in the same space, picked from our database by type, price, and score.

xTool D1 Pro 40W laser engraver by xTool

xTool · Diode · $999

The 40W D1 Pro module swaps onto the same frame as 5W–20W heads. Best cut headroom in the line; verify optical power on the listing.

xTool P2S laser engraver by xTool

xTool · CO₂ · $4,799 – $5,499

The P2S refines the original P2 with better software and autofocus. Same 55W CO₂ class for acrylic and wood production. Still xTool's main enclosed CO₂ below the P3 flagship: choose P3 if you need 80W and automation; P2S if 55W and budget fit.
