the focus position when it initially sets or lenses and lasers are replaced. For details about
operating system parameters, please refer to the system instructions.
Manual dot can refer to the following steps:
1. To attach one textured tape on nozzle tip and adjust the scale to biggest value, and set
laser power to 80-100w;
2. While moving each 0.5mm (as small as possible), shot a hole on the textured tape;

smallest hole is zero focus. The focus is just at the tip of the nozzle.
