CO2 Laser Cutter — Owner's Manual

Safe operation depends on independent safeguards, not on operator attention. Three protect routine cutting: the lid interlock prevents the laser firing while the enclosure is open, the job starts only on operator command, and the beam stays inside a closed cabinet. All three must fail before anyone is exposed.

Do not defeat any of them. Never bypass the lid interlock, never run with a panel removed, and never operate the machine with the enclosure open.

1. 01

   Keep the enclosure closed

   CO2 laser light is infrared and invisible. Keep the lid closed for every job. Never bypass the lid interlock.

2. 02

   Do not leave a running job

   The beam cuts by burning. Stay with the machine for the full cut. Keep a CO2 or Class ABC extinguisher within reach and clear scrap from the bed between jobs.

3. 03

   Know the emergency stop

   The emergency stop cuts laser power immediately. Locate and test it before first use. On flame, smoke, unusual odor, or any electrical fault: press the emergency stop, then disconnect main power.

4. 04

   Electrical

   Connect to a grounded 110 V / 60 Hz outlet on its own circuit. Do not use extension cords or power strips; a surge protector must be rated over 2,000 J. The cabinet contains high-voltage components. Do not open it. While the laser key is on, touch the machine with one hand at a time — a habit that keeps any accidental shock from crossing the chest. Contact SWYFT Robotics support before any electrical service.

5. 05

   Fire response

   Cut power — emergency stop, then main power — before using the extinguisher. Discharging too close to the flame can scatter burning debris; know your extinguisher's working range. Post the local fire department's number where the machine is used.

6. 06

   Pass-through doors

   The pass-through doors let long stock feed through the enclosure, and open a path for scattered beam energy. When either door is open: only material passes through the opening, everyone nearby wears laser safety glasses rated OD 5+ at 10.6 µm, and extraction must still capture the fumes. Close both doors when not in use.

7. 07

   Student operation

   Students operate only with a trained adult supervising, every session — supervision is not a training phase that ends. New operators complete a supervised start-to-finish job before running the machine, and review the emergency stop, extinguisher location, and ventilation at the start of every build season.

All three models include one-button autofocus, a red-dot pointer, front and rear pass-through doors, honeycomb and aluminum blade beds, an electric bed lift, a lid interlock, coolant flow protection, and an emergency stop.

Every control and access point referenced in this manual is labeled below on the 130 W flagship. The two 100 W models and the Compact share the same layout at smaller scale — lid, bed, gantry, and electronics bay are in the same relative positions on all four machines.

The tube at the rear generates the beam; three mirrors relay it to the head, where the lens focuses it onto the material. Understanding this path explains most of this manual's maintenance: two of the three mirrors move with every job, so alignment (chapter 4) and mirror cleaning (chapter 7) are what keep cutting power at the material.

1. 01

   Remove all shipping restraints

   Foam blocks and zip ties secure the gantry and head in transit. Remove every one before jogging the machine. Retain the packaging for future transport.

2. 02

   Inspect for transit damage

   Check the tube, mirrors, and lens. Photograph any damage and email support@swyftrobotics.com before powering on.

3. 03

   Position the machine

   The 130 W is a floor machine at 1860 × 1320 × 940 mm and 400 kg. The two 100 W models are 600–630 mm tall; the Compact is 93 kg and requires a rigid stand or bench rated for its weight. All models ship by freight on a pallet.

4. 04

   Allow clearance

   Leave generous space on every side for airflow, access, and the exhaust run. Position near the vent exit and a grounded outlet. Keep a separate work table nearby so nothing is ever staged on top of the machine.

5. 05

   Control the room

   The room must hold 5–35 °C and stay under 70% humidity, clear of the dew point — condensation on cold optics and electronics is a fault waiting to happen. Keep the machine out of direct sunlight and away from dust, strong electromagnetic sources, and anything flammable or corrosive stored nearby.

1. 01

   Connect the coolant lines

   The pump outlet feeds the tube inlet. The tube outlet returns to the pump inlet. Flow travels in the same direction as the beam, toward mirror 1. Secure every connection with a clamp.

2. 02

   Fill with distilled water only

   At least 7.5 L (2 gal), enough to keep the pump fully submerged. Tap water scales the tube; additives and automotive antifreeze leave conductive, corrosive residue. Top up every few days — evaporation will expose the pump. Never handle the pump or reach into the tank while the pump is powered; unplug it first.

3. 03

   Confirm flow before firing

   Run the pump and confirm water moves through the tube with no trapped air. Pinch and release the line to clear a bubble. Hold coolant at 15–21 °C; never below 10 °C or above 38 °C — cold shock and overheating both crack the glass. On hot days, floating sealed bottles of ice in the tank cools the water without diluting it. Confirm flow before every session. Do not rely on the flow sensor alone.

4. 04

   Using a chiller instead

   An industrial water chiller replaces the pump and tank and holds temperature automatically. Connect the chiller's outlet to the machine's water inlet and its inlet to the machine's water outlet, and run it on a separate circuit where possible.

Duct the exhaust blower outdoors or to a carbon filter rated for laser fumes. Keep the run short and straight. Long or kinked hose reduces airflow and leaves smoke staining on cut edges. Connect the air assist pump and confirm air is delivered at the nozzle.

1. 01

   Power on and note the home corner

   Release the emergency stop and switch on. Let the controller boot and home the head. The corner it homes to is the origin.

2. 02

   Set focus

   Place material on the bed and press autofocus on the control panel. Manual alternative: rest the included acrylic focus gauge on the material and raise the bed until the nozzle just touches the gauge without pressing on it. Never focus, by either method, without material on the bed.

3. 03

   Position the computer

   Keep a USB- or Ethernet-connected computer within about 4.5 m (15 ft) of the machine — longer runs invite signal dropouts mid-job.

4. 04

   Frame the job

   With the lid closed, use Frame to trace the job outline with the head before cutting. This confirms material position and that the job fits the bed.

Cut a test grid at the starting values for your material from Section 6. Adjust speed, power, and passes until edges are clean and the cut drops through. Save the working values as a LightBurn material entry. Watch the first pass of any new job.

The laser power supply runs at several thousand volts, and a solid earth ground is what makes a fault survivable. A properly wired three-prong grounded outlet provides this. Never lift the ground with a 3-to-2 adapter, and never run the machine ungrounded.

If no grounded outlet exists at the location, the cabinet's dedicated grounding lug must be bonded to earth before first power-on: a single rod driven at least 2.5 m (8 ft) into soil — or two rods at least 1.2 m (4 ft) each — placed at least 1.5 m (5 ft) from the machine, with no more than 5 Ω of resistance end to end. Have the connection checked periodically for corrosion and loosening. If that is not practical at your site, have an electrician install a grounded outlet instead — that is the better fix.

The machine ships with the emergency stop pressed in; release it by pulling up. Before the first real job — and after any move or service — prove both safety interlocks work. Both tests run with the cover closed and scrap material on the bed.

1. 01

   Test the emergency stop

   With coolant running and scrap on the bed, fire a brief test pulse from the control panel, then press the emergency stop mid-pulse. The laser must cut off instantly. If it keeps firing, stop — the machine is not usable until the switch is replaced. Contact support@swyftrobotics.com.

2. 02

   Test the lid interlock

   Start a small job on scrap, then open the cover. The beam must stop the moment the lid lifts. If it does not, stop and contact support. Never operate a machine whose interlocks fail, and never disable them.

Alignment is required only after a laser tube or mirror is replaced, or after visible transit damage. It is not routine maintenance and not a seasonal task. Do not adjust the mirrors to increase cutting power.

Weak or uneven cutting is usually one of the following. Each is safe to check with the machine shut down and the enclosure closed.

Contact support@swyftrobotics.com. In most cases the cause can be identified by email, and alignment can be carried out on a call or arranged as a service visit. This manual does not publish an alignment procedure.

LightBurn drives all three models and is the recommended software. Download it from lightburnsoftware.com for Windows or macOS. A Ruida machine requires the tier that supports DSP controllers. Check LightBurn's site for current tiers and pricing.

1. 01

   Add the machine

   Devices → Create Manually. Select the controller for your model. The 130 W uses a Ruida RD6445. The two 100 W models ship with AutoLaser and are not Ruida; check the controller label, or contact support. Enter the bed dimensions from Section 2.1.

2. 02

   Connect

   Connect over USB or Ethernet. Confirm the status bar reads Ready. Save a backup of the default settings.

3. 03

   Import from CAD

   Export as DXF and import with File → Import. Assign layers by color.

4. 04

   Set speed and power per layer

   Set values for each color layer in the Cuts / Layers panel, starting from Section 6.

5. 05

   Frame, set origin, run

   Set focus, frame the job, set the origin, then start. Watch the first pass.

Each machine ships with its bundled software on the included USB drive. The 130 W includes RDWorks 8, which opens .rd files. The two 100 W models include AutoLaser. Both run offline and are useful where the machine has no network access. Supported import formats across the range include DXF, AI, SVG, BMP, and JPG. Transfer over USB, Ethernet, or USB drive.
