Laser engraving is a powerful, precise and versatile technology. It can be used to create designs on a wide variety of materials, from wood and metal to leather and acrylic. However, despite its apparent ease of use, many errors can compromise your results. Some can even damage the machine or represent a hazard. To help you succeed in your projects, here are the top 5 mistakes to avoid when using a laser engraving machine.
1. Neglecting focus adjustment
One of the most common mistakes is to set the laser focus incorrectly. Yet this detail is essential to guarantee sharp, precise engraving.
👉 A poorly focused beam can result in blurred engraving, irregular edges or loss of power.
Our recommendation
Before each use, check that the distance between the laser head and the surface of the material is correct. Some LaserKube models are equipped with autofocus systems: use them for greater precision.
2. Use unsuitable materials
Not all materials are compatible with laser engraving. Some give off toxic fumes, while others melt or blacken.
For example:
- PVC gives off hydrochloric acid vapours, which are extremely hazardous to health and to the machine.
- Unidentified plastics can produce corrosive residues.
- Teflon emits potentially carcinogenic fumes
Our recommendation
Always enquire about the material before engraving. At LaserKube, we provide a list of tested and safe materials.
3. Forget about regular machine maintenance
Like any precision tool, a laser engraving machine requires regular maintenance. Otherwise, residues can build up and impair beam quality.
Therefore :
- Clean lenses and mirrors regularly.
- Check and grease rails and belts.
- Check the ventilation system for clogging.
- Change extraction system filters regularly.
Neglected maintenance can reduce the machine’s lifespan, or even lead to costly breakdowns.
4. Underestimating the importance of safety
Another common mistake is not taking safety instructions seriously. Yet laser beams can cause burns or serious eye injury.
🔴 What’s more, the combustion of certain materials can generate fumes that are harmful to health.
Our recommendations
- Always wear suitable safety goggles if the machine is in class 3 or 4.
- Work in a well-ventilated area or with a fume extractor.
- Never leave the machine unattended during operation.
5. Incorrect power or speed settings
Finally, the wrong combination of speed and power is a common mistake, especially for beginners.
- Too much power or too slow a speed can burn the material.
- On the other hand, too high a speed can result in too light or incomplete engraving.
Our recommendation
💡 There’s an optimum setting for every material. Always test on a scrap before launching your final production.
In a nutshell
Laser engraving is an accessible technique, but one that requires rigor and method. By avoiding these 5 common mistakes, you’ll not only optimize the quality of your creations, but also preserve your machine in the long term.
