Place the plate to be engraved on the honeycomb board and fix it with press nails to prevent it from moving. Place a frosted aluminum plate under the honeycomb board to protect the tabletop.
Properly adjusting the focus before laser engraving is crucial to ensuring the quality of the engraving. Here are the detailed steps to adjust the focus:
Prepare the Focusing Post:
The focusing post is a tool to assist in adjusting the laser focus, which usually has multiple scale steps, each corresponding to a different height.
Place the Focusing Post:
Place the focusing post between the surface of the engraving object and the machine’s adjustment block, ensuring that the focusing post is stable and perpendicular to the worktable.
Adjust the Z-Axis Lift Module:
Operate the Z-axis lift module, which is typically done through the machine’s control panel or software interface.
Slowly adjust the Z-axis until the laser head descends and makes contact with the first step of the focusing post.
Precise Focusing:
When the laser head makes contact with the first step of the focusing post, stop further descent.
At this point, the laser focus should be exactly on the surface of the engraving object.
Conduct a Test:
Before starting the actual engraving, it is recommended to do a test to ensure the accuracy of the focus.
Observe the size and clarity of the laser spot on the object’s surface, and make minor adjustments to the Z-axis position if necessary.
Safe Operation:
Throughout the adjustment process, ensure to follow all safety guidelines and wear appropriate protective equipment, such as laser safety goggles.
