Difference between Auto-focus and Manual-focus with Snapmaker Laser engraving module

Auto-foucs

  1. If the machine is not yet connected to Wi-Fi, please select Settings in the main menu, tap Wi-Fi and connect to your network.

  1. Before you connect your computer to the machine, make sure both the computer and the machine have connected to the same Wi-Fi. Open Snapmaker Luban and go to Workspace 21.pngConnection → Select Wi-Fi → Click22.png → Select your device → Click Open → Tap Yes on the touchscreen.

  2. Go to Laser G-code Generator23.png and select Load G-code to Workspace to load the generated G-code to Workspace .

  1. Use **X- / X+ / Y- / Y+ ** to move the laser dot to where the work origin will be, click Set Work Origin and Run Boundary to check if the work origin is at the right place.

Note : If the work origin is set up incorrectly, please reset the work origin and run boundary again.

  1. Click28.png to start engraving / cutting.

Note 1 : The computer must be connected to the machine via Wi-Fi throughout the process.

Note 2 : You can change the settings for Laser Power and Work Speed during the engraving / cutting process.
Note 3: The Laser module will reach a height of (Material thickness + Laser height).
Note 4: “Z” button on the touchscreen will grey out and the machine will consider the height of (Material thickness + Laser height) as the focal distance.

Tips : If the material thickness is unknown, you can deselect Printing Auto Mode and change to Printing Manual Mode .

When using the Printing Manual Mode , please do the following:
Set a relatively small value (e.g. 1%) for Laser Power and turn on the laser beam → Use X- / X+ / Y- / Y+ / Z- / Z+ to move the laser dot to where the work origin will be → Use Z- / Z+ to adjust the height of the laser module until the laser beam is focused down to the smallest spot → Click Set Work Origin → Click Run Boundary → Click28.png to start engraving / cutting.

Note : If the work origin is set up incorrectly, please reset the work origin and run boundary again.

Manual-focus

  1. If the machine is not yet connected to Wi-Fi, please select Settings in the main menu, tap Wi-Fi and connect to your network.

  1. After the machine has received the G-code file, tap Yes on the touchscreen to access the preview page for engraving/cutting.
    Note 1 : If you want to learn more about the Auto Mode and Manual Mode before you start engraving / cutting, you can go to section Auto mode and Manual Mode.
    Note 2 : Files sent via Wi-Fi are saved in the FilesLocal on the touchscreen.

Tips:

  • When using the auto-focus, the machine will consider the proper focal distance equals the sum of material thickness and laser height.
  • Laser height is a safety distance of the Laser engraving module, which should be from 21 - 25 millimetres.
