• B. Belt Tightness: The belts in the machine control the movement of the laser
module. If the belt is too loose, the laser's movement may not be precise, leading
to crooked lines. On the other hand, if the belt is too tight, it could cause excessive
tension and affect smooth operation. Adjust the belt tightness manually if
necessary.
Note:
• Effect of Gravity: If the laser module is under the effect of gravity, it may slide
slowly along the X-axis profile, which is perpendicular to the desktop. This could
cause unintended movements during engraving, leading to an inaccurate design.
Ensure the machine is properly leveled and secured.
• Pulley Assembly: Check the laser head assembly to ensure that there is no idle slip
on any pulley during operation. Idle pulley slippage can negatively affect the
precision of the engraving process.
• Belt Tension: Ensure that the belt tension is appropriate for your project. If the belt
is too loose or too tight, the laser's movements may become unpredictable. If
adjustments are needed, refer to the instructions on how to manually adjust the
belt.
• Is it possible to engrave on reflective or transparent materials, such as ceramics or
glass?
Answer: Yes, it is possible to engrave on reflective or transparent materials such as ceramics
or glass; however, there are specific precautions you need to take to ensure the quality of the
engraving and the safety of the laser module.
• Anti-Reflective Material: Before starting the engraving process, it is highly
recommended to apply an anti-reflective coating or material to the surface of the
reflective or transparent material. This coating will help prevent the laser from
reflecting back onto the module, which can cause damage to the machine or
result in an ineffective engraving. Reflective surfaces, like glass, tend to bounce the
laser beam, reducing the accuracy and effectiveness of the engraving. The anti-
reflective coating absorbs the laser, ensuring it penetrates the surface properly to
create the desired engraving effect.
• Material Handling: Depending on the type of reflective or transparent material,
you may need to adjust the laser's power, speed, and focus to achieve optimal
results. For glass, for instance, you may need to engrave at a lower speed with
higher power to ensure that the laser adequately etches the surface.
