User Manual
4.2 The Focus Position Adjustment
BM109 is equipped with automated focusing system. But it still needs to dot manually to
redecide the focus position when it initially resets or replaces lenses, lasers, etc. For details about
operating system parameters, please refer to the system instructions.
Manual focus can refer to the following steps:
1. The laser head scale is displayed to the maximum, and the laser power range is set to 80-100w;
2. Then, within each moving 0.5mm (as small as possible), open a laser hole on the textured
paper;
3. Punching for several times, finally compare and find out zero focus, namely the scale
corresponding to the hole with the smallest aperture, that is, the focus is just at the end of the nozzle
section.
