There are two modes to adjust the laser height for the 3-axis 20W/40W laser machining on Snapmaker 2.0. You can select between them on the Choose Mode screen.
If you have calibrated the platform height and know the thickness of the material, you can use this mode to adjust the laser height.
As the focal length of the 20W/40W Laser Module is fixed, the machine will automatically adjust the Z-axis height of the toolhead during the task to ensure that the focal point falls on the surface of the material, based on the offset of the platform and the input material thickness.
¶ Before You Start
- Measure the thickness of the material.
- Complete the Platform Height Calibration.
¶ Procedures
- On the touchscreen, select the G-code file in the file list and tap Next to enter the laser job preparation.
- On the Choose Mode screen, select the Input Material Thickness Mode.
- Set the thickness of the material.
This mode adjusts the laser height with the help of the focus lever.
As the focal length of the 20W/40W Laser Module is fixed, when the focus lever touches the material:
- If the line above the knob aligns with Scale 0, the laser beam will focus right on the surface of the material.
- If the line above the knob aligns with other scales, the focal point will move deeper inside the material.
¶ Procedures
- On the touchscreen, select the G-code file in the file list and tap Next to enter the laser job preparation.
- On the Choose Mode screen, select the Focus Lever - Assisted Mode.
- Follow the on-screen instructions to adjust the laser height.
