LS Series

Boss’s floor-standing CO₂ platform for wood, acrylic, leather, glass and stone. It comes in four bed sizes, and for most shops the size is the real decision: pick the bed that holds the biggest piece you’ll run, then choose the power.

Is it the right machine

What the LS is for, and where it stops.

The LS is the default answer for most non-metal work. It is not the answer for every job, and it’s cheaper to find that out here.

A good fit when…

  • Cutting and engraving wood, acrylic, leather, paper and fabric on one machine
  • Engraving glass, stone and coated drinkware, flat on the bed or turning on a rotary
  • Running orders all day, not just samples: it’s built for that duty cycle
  • Marking pre-treated metals

Look elsewhere when…

  • You need to cut sheet metal. The HP Series carries the same 155 W tube with a metal-cutting head, good to about 18-gauge stainless.

  • You’re marking bare metal. A fiber marker does that directly, without a coating.

  • Fine glass or precision ceramic, where CO₂ frosting is too coarse.

  • You don’t have a shop yet, or you’re proving a product before you commit.

The models

Four sizes. Same platform.

Every LS includes honeycomb and knife-blade cutting platforms and an exhaust fan with venting pipe. Power, cooling, air assist and drive are chosen when you buy.

Boss LS-1420
Small format

LS-1420

The smallest LS. Four-way pass-throughs let longer stock run through the machine, and Boss lists its 70 W tube as cutting up to 3/8″ wood and acrylic.

LS-1630

A longer bed than the 1420 (29.5″ against 19.75″), for signs, boards and panels that run long.

Choosing a size

Size by the largest piece, not the smallest.

The bed sets the biggest piece you can lay flat. Start from the sheet or blank size you actually buy, then check the room: the two large LS machines ship in crates about 7 feet long.

Moving up a size buys bed area, not cutting depth: the LS-2440 and LS-3655 are sold at the same power levels.

Choices at purchase

The options that change the machine.

These are picked on the Boss store when you buy. The guides explain what each one does to the work.

Laser power

Sold per model: LS-1420 70 W, LS-1630 80 W or 105 W, LS-2440 and LS-3655 105 W or 155 W. On wood, more power means faster, not thicker.

Cooling

The LS-1420 and LS-1630 are sold with a water pump or a CW-5200 chiller. On the LS-2440 and LS-3655, Boss’s listings say the 155 W tube includes a chiller.

Air assist

The LS-1420 and LS-1630 offer an air pump or a compressor; the LS-2440 and LS-3655 a compressor. Every LS can run on your own air instead. How air assist changes a cut.

Drive

The LS-2440 and LS-3655 offer a hybrid servo drive at 1,500 mm/s or the Mach 4 servo at 2,300 mm/s. The smaller two run hybrid servo.

Rotary

The LS-1420 takes its own short rotaries; the LS-1630, 2440 and 3655 share the larger set. Do I need a rotary?

Lens

Focal length trades spot size against depth of field. Choosing a CO₂ lens.

Questions

What people ask before choosing an LS.

Straight answers from Boss’s published specs.

What’s the difference between the LS and HP Series?

HP stands for Hybrid Processing. An LS with a 155 W tube and an HP with a 155 W tube carry the same laser; the HP ships with a metal-cutting head that delivers air assist differently, and that head is what lets it cut thin sheet metal, about 18-gauge stainless or 20-gauge mild steel.

If you won’t cut metal, the LS is the machine. If you will, look at the HP.

Will a bigger LS cut thicker material?

Not by itself. The bed and the tube are separate choices: the bed sets how big a piece fits, and the tube’s power sets how fast and how deep it cuts. The LS-2440 and LS-3655 are sold at the same power (105 W or 155 W), so the bigger machine buys area, not depth.

For scale, Boss lists the LS-1420’s 70 W tube as cutting up to 3/8″ wood and acrylic.

Which LS size do I need?

Start from the largest piece you’ll run, not the smallest: the sheet you buy, the biggest sign, the widest hide. Choose the bed that holds it flat, then check the room and the doorway against the crate sizes above.

If your work doesn’t fit one obvious size, the Spec Desk will size it to your parts.

What comes with an LS?

Every LS includes honeycomb and knife-blade cutting platforms and an exhaust fan with a venting pipe. Boss’s published warranty is 2 years on parts and 1 year on the laser tube.

Laser power, cooling, air assist and (on the two large models) the drive are chosen on the Boss store when you buy.

Not sure which size?

Tell the Spec Desk what you make and the biggest piece you’ll run. They’ll size the machine to the work.

Specs are Boss’s published product-page spec tables (verified 2026-07-30). Laser power, drive, cooling and air-assist choices are read live from the Boss store, which is where current pricing lives.
