Beam Focus position Adjustment
Even BM111 is equipped with automated focusing system, it still need dot manually to
re-determine the focus position when users replace the lens or lasers. For details about operating
system parameters, please refer to the system instructions.
Manual dotting 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), activate the laser to make a hole in
the textured paper;
3. Dotting several times, finally compare and find out the scale corresponding to the smallest
hole, which is the zero focus position, that is, the focus spot is just at the end of the nozzle end face.
