Practical advice about sensors, CNC equipment and CO2 laser operation: from spindle selection to cooling, optics and diagnostics of common faults.

Sensors and motion control

Position or rotation angle sensors: encoders

A short explanation of how encoders work, what A and B channels are used for and what can be determined from a quadrature signal.

CO2 laser maintenance

Most common CO2 laser problems

How to recognize power loss, cooling problems, contaminated optics and other faults that most often cause downtime.

CNC equipment

Practical advice about spindle power, the frequency inverter, mechanical load and real compatibility with CNC machines.

CO2 laser cooling

Why stable water flow and temperature control are essential for CO2 laser power, stability and tube lifetime.

CO2 laser power

When higher power helps, when it gets in the way and why engraving does not always benefit from the most powerful tube.
