2.11 Engraving problem—the engraving quality is very poor
Here are the reasons:
 The needed focus is lost
The bending of the material or the uneven working table can result in different focal lengths,
especially for the large engraving graphic.
Please fix the material with magnet and check if the working table are the same height, then
calibrate according to the link below.

 The focus lens and reflective mirror are dirty
 The laser beam path is not aligned

When the laser head move to four corners of the working table, check if the laser beam lasers to
the same position on the third reflective mirror.
