The dynamic focusing scanning galvanometer is marked with three state lights, X, Y and Z, of which X and Y
indicate the working status of 2D scanning module XY galvanometer, and Z is the working condition of dynamic
axis. When the light turns green, the system is working properly; if the light turns red, it indicates a failure.

Dynamic axis adjustment
Reinstall the focusing lens group after adjusting the optical path of the galvanometer. The focusing lens
group is locked, and the dynamic axis module can slide freely. Non-electric focusing galvanometer needs the
following adjustment of dynamic axis:
1. Place a piece of black cardboard on the working platform, draw a 200*200 rectangle with the software, set the
fill spacing to 1mm, and then set the processing parameters as shown below:

Dynamic Axis Adjustment Parameters
2. The galvanometer has a vernier caliper connected to the dynamic axis. First loosen the screws on the calipers,
push the calipers to the zero position far left, then click Mark and move the dynamic axis back and forth. When
the marking sound is the most strident, the dynamic axis is in focus position, and the dynamic axis can be locked
with the screws. (Do not move the dynamic axis with hand while marking because it is very dangerous when laser
passes through) Since the machine is relatively high, the operation requires at least two persons, with one person
adjusts the dynamic axis in the above, and the other operates the console and listens to the marking sound. After
adjusting, fix the dynamic axis and seal the entire optical path.

Galvanometer correction
For the correction of galvanometer, please refer to the operation manual of the machine and related host
software manual.

Commissioning
After the above steps, the commissioning of motion and laser completes, and drawing test can be started.
