Lightburn has the ability to perform multiple types of cutting and engraving laser operations (See Lightburn documentation for additional details). In some cases, for example when your spindle is controlled by this value, this value can be set in the Lightburn CNC software.ġ0. This version of the GRBL also doesn't provide the option to change the set Spindle PWM range. For GRBL v0.9j and older, the GRBL setting $30 (Maximum Spindle Speed / RPM) can't be altered. It is important that it is kept off in other cases.ĩ. Enable Laser Fire Button OFF - this button is only meant to be used to help with calibration and to show the user where the laser beam is currently pointing.For GRBL v1.1f, v0.9c and newer, you can access them by going to Lightburn > Edit > Device Settings. The settings depicted below are likely to give you the best performance of your Opt Lasers Grav cutting and engraving laser. Make your new device the default and click OK.Ĩ.

Set the origin of your Opt Lasers Grav cutting and engraving laser to Front Left.ħ. You can reference your GRBL settings by sending $$ to view your maximum distance. You can find the suitable working dimensions at Carbide3D Support web page. This sets up the maximum distance that can be travelled by the cutting and engraving laser in the x axis and y axis. Input the x-axis length and y-axis length. This shows up as Lightburn not being able to find your cnc laser (can't connect). If you run other software, like RDWorks, Easel, Carbide Create, Carbide Motion, AutoLaser, LaserCAD, etc, make sure that software is not running when you run LightBurn.ĥ. Important: There are certain programs that can lock Lightburn out of laser control, which can cause a sudden stop of operation or issues with installation. Input the name of your device, for example 'Opt Lasers Grav engraving laser' or 'Shapeoko (GRBL)'. See Lightburn's documentation for additional information (available at GitHub -> LightBurnSoftware -> Documentation). The first time that you launch Lightburn you will be prompted to setup your cutting and engraving laser device. MacOS users may need to go to > System Preferences > Security and Privacy > General, then click 'Open Anyway' and 'Open'.ģ. Alternative options include GRBL and other laser software suitable for more advanced users.ġ. Lightburn is the recommended software to use with Shapeoko for laser engraving and cutting applications.
