iKier Master 50W: a CO2 laser cutter built to stay calibrated after transport

What it is

A batch of engraved acrylic pieces, a wood panel cut clean along the edges, a design transferred from a USB drive in minutes: this is the use case the Master 50W is built for, the CO2 laser cutter iKier presents as its first flagship model. Designed for makers, small workshops and craftspeople who engrave and cut regularly, it houses a 50 W CO2 laser, complemented depending on the version chosen by a 1.6 W infrared module. The machine comes in several configurations: Master alone, Master paired with the 1.6 W IR module, bare machine, or bundled with a rotary roller, conveyor, air purifier, up to an all-in-one package that combines these accessories.

Why it exists

According to iKier, the Master 50W can engrave more than 400 different materials, from wood to acrylic and other common workshop surfaces. The brand highlights its FlyLock optical system, said to improve resistance to vibration and greatly reduce the need to recalibrate the machine after it has been moved — a classic issue for anyone transporting their laser between locations. It also states that one-click autofocus simplifies focusing before engraving, and that batch refilling takes only 3 seconds, allowing pieces to be processed one after another without losing time between cuts.

What matters

The CO2 laser delivers 50 W, optionally complemented by a 1.6 W infrared module. This combination opens the door to materials that respond differently to light: CO2 suits wood, acrylic or leather, while infrared is better suited to marked metals or certain plastics. This covers several types of projects without needing to switch machines.

The work area measures 500 × 300 mm as standard, but extends to 800 × 500 mm with the optional conveyor. In practice, this makes it possible to process longer pieces than a standard sheet, by feeding them under the laser head rather than limiting them to the fixed bed size.

Maximum cutting speed reaches 800 mm/s, paired with a maximum cutting capacity of 18 mm in acrylic and 13 mm in wood. These figures place the Master 50W in the medium-thickness bracket: a 13 mm wood panel or an 18 mm acrylic sheet goes through in a single pass, while a thicker piece will require several passes.

A high-pressure pump powers the air assist system at 28 L/min. This airflow clears smoke and cutting residue from the work area while the laser is running, which limits burn marks on the edges of pieces and protects the lens from debris.

The machine includes a 16 MP HD positioning camera and a physical-probe autofocus, both used to precisely align the design on the material before starting a cut. iKier states an optical stability of 99.7 % after transport, a figure that directly addresses the recalibration issue mentioned above.

Two safety mechanisms equip the Master 50W: an emergency stop triggers when the lid is opened, and flame detection causes an automatic shutdown if abnormal combustion is detected. On the warranty side, main components are covered for 24 months, the CO2 laser tube for 6 months, and wear parts for 3 months.

Day to day

The contents of the box give a sense of the setup involved: the machine itself, a funnel, an exhaust hose, a hose clamp, a fan bracket, a Phillips screwdriver, a camera calibration target, kraft paper, a USB drive, a USB Type-C cable, a power cable, a spare lens, a lint-free cloth, a set of H2, H2.5 and H3 hex keys, and a user manual. This is enough to connect fume extraction, calibrate the camera using the supplied target, then transfer the first files via the USB drive or the Type-C cable.

Routine maintenance involves cleaning the lens with the supplied lint-free cloth, a wear part covered for three months under warranty. The hex keys included in the box allow work on fixings without extra tools.
