. The main window of LightBurn
This is the default layout for the main LightBurn window, which includes Menus, Main Toolbar, Creation & Modifier Tools, Color Palette, Cuts / Layers, Laser Window, Move Window etc.
Menus: The menu bar at the top of the main window provides the access to almost every feature available in LightBurn, like File, Edit, Tools etc.
Main Toolbar: The main toolbar in LightBurn provides quick access to commonly functions for opening or importing files, saving, using the clipboard (copy & paste), moving or zooming the view. Right beside it is the Arrangement toolbar, containing some commonly used arrangement tools for arranging and aligning shapes.
Tool tips: If hover the mouse over a control, then a small bit of text pop up that describes that button or feature, like this:
Color Palette, these colors are used to assign different kinds of parameters to the shapes in the design.If a design is selected, click a color entry will apply that color to the shapes in your selection. The colors currently in use in your design will also appear as entries in the Cuts / Layers window, where you can choose the operations that each color will represent.
Cuts / Layers: The first column shows the name you've assigned to this layer, followed by the color, then the Mode (Line, Fill, both, or Image). Then the speed and power are displayed, followed by the options to enable or disable sending this layer to the laser, or displaying it in the workspace. Underneath the layer list you can see and change the basic settings for the currently selected layer. Double-clicking an entry in the layer list, it will bring up a larger Cut Settings Editor with a more complete set of options.
Double-clicking an entry in the layer list will bring up the full Cut Settings Window, allowing you to edit to all the settings.There are three modes that are often used, namely Line, Fill and Image.
In Line mode, the laser follows the exact path of selected design, tracing the lines with the beam enabled at the setting power and speed. If laser moves quickly, or with low power, it will likely just etch the surface. If laser moves slowly and with high power, it will cut through the material. The only difference between surface marking and cutting is the power and speed. Fill mode permits the laser to scan line by line and fill in the selected shape, which will fill in closed shapes but not open shapes. Image mode is only available for images, and can control how LightBurn renders the image data on the laser. There are three iamge modes that are often chosen, which are Atkinson, Stucki, Jarvis.
Laser Window: The Laser Window is used to select the active machine, test the framing (the artwork's outer bounds), run and stop the machine, and choose the file processing, order, and artwork positioning within the workspace.
There are two Frame buttons are used to preview the position of the job on the laser. The first is a standard rectangular frame, also called a 'Bounding Box'. This is the smallest rectangle that will fully contain the shapes selected. The O-Frame button, called the 'Rubber Band Frame', traces a path around selected design that is the shape of a rubber band stretched around it. The speed and laser power during frame are adjusted in the MOVE window. Due to software limitations, the maximum speed during frame can be 10,000 mm/min.These two different frame effects can be shown in
the following figure:
Console Window: The Console window displays messages from the controller and commands sent to it by LightBurn, and some macro commands designed of Nano engraver. It can also input direct commands to engraver through this window, such as $$ to display GRBL settings, $X is to unlock machine if it has been locked due to an alarm or error. The Console window will also display alarm or error messages sent to LightBurn by the laser's controller, indicating that there was a problem with the machine's operation.
