Before Your Laser Arrives: The Setup Checklist Every New Owner Needs

Choosing the machine is the exciting part. But a laser doesn't just need a corner to sit in — a little planning before delivery day makes everything that follows easier, safer and better for your results. Here are the five things to think through.

1. Space

• Allow more room than the machine's footprint. As well as the laser itself (and its stand), you'll need space alongside for the chiller, extractor fan and air pump or compressor.
• Think about clearance: the lid opens upwards, you'll want comfortable access for loading materials, and you'll need to reach the back for maintenance and ducting.
• Measure the route in before delivery — doorways, corners and steps. These machines arrive crated on a pallet, and they're bigger than the photos suggest.
• Pick somewhere dry and frost-free. Damp garages and freezing workshops are hard on electronics and water-cooled machines alike.

2. Ventilation

• Every cut and engraving produces smoke and fumes, and they need to go outside — this is not optional.
• Plan the shortest, straightest duct run you can to a window or external wall. Every bend in the ducting reduces how well the extraction works.
• The fan supplied with most machines is adequate to start with, but an upgrade makes a real difference — especially on longer duct runs. Our recommendation after years of commercial use is the AC Infinity CLOUDLINE S6 — a 150mm inline duct fan with a speed controller that runs quietly and seemingly forever. It's the one we'd buy again without hesitation.
• One safety note: some materials, such as PVC and anything containing vinyl, should never go in a laser — the fumes are toxic and corrosive. If you're not sure about a material, ask before you cut it.

3. Power

• Most machines will run from a standard socket, but remember you're powering the laser, chiller, extractor and air supply together — think about the combined load on the circuit.
• Have enough sockets close to the machine. Avoid daisy-chained extension leads, and a surge protector is a sensible bit of insurance.

4. Cooling

• CO2 laser tubes are water-cooled, and a stable water temperature means consistent cutting and a longer-lasting tube. A proper chiller is one of the best investments you can make — read our full chiller guide before buying.
• Allow space for the chiller and fill it with distilled or deionised water, not tap water.
• A UK-specific warning: if your machine lives in a garage or outbuilding, protect it from frost over winter. Frozen coolant can crack a laser tube — an expensive lesson nobody needs.

5. Air assist

• Air assist blows a jet of air at the cutting point, clearing smoke from the cut, reducing charring and flare-ups, and keeping your lens clean. Run the machine with it on, always.
• OMTech machines come with a built-in air pump — it works, but upgrading it makes a noticeable difference to cut quality and lens cleanliness.
• The upgrade we run on both our machines: the Hailea Enviro ET-120 Silent Air Pump — essentially a pond aerator, but significantly more powerful than the standard OMTech pump. The swap takes about ten minutes: unplug the air hose and electrical connection from the built-in pump and connect the air hose to the Hailea instead. You'll need a reducer to match the hose diameter to your machine's fitting, but the whole job is simple.
• Why a pond pump rather than a compressor? A compressor is noisier and — critically — introduces moisture into the air hose, which can contaminate the lens and cause problems. A moisture trap is essential with a compressor. The Hailea runs all day, every day, quietly and dry. No moisture issues, no noise, no trap required.
• Whatever you use, factor in its space, power and noise alongside everything else.

Not sure about your setup? Come and see one running

The easiest way to make sense of all this is to see a complete setup working. As the only showroom covering the north of England and Wales, we can show you the machines, the ducting, the cooling and the air assist all in action — and talk through how it would fit your own space.

Get in touch before you travel and we'll have everything ready for your visit. And if you'd like to go from set up to confident, our hands-on training course is bookable in person or by video call.
