You can, optionally, define a vertical coordinate system for a map or scene.Įmpty maps and scenes derive their coordinate systems from the first layer added to them. A map or scene always has a horizontal coordinate system. There are numerous coordinate systems to choose from for maps and local scenes, but the horizontal coordinate system for a global scene is limited to either WGS84 or China Geodetic Coordinate System 2000 (CGCS 2000). For global scenes, the default horizontal coordinate system is WGS84. In a new, empty map or local scene, the default horizontal coordinate system is WGS84 Web Mercator. Coordinate systems can be defined in both maps and scenes. Coordinate systems can be horizontal, defining where features are across the globe, or vertical, defining how high or deep features are relative to a surface. A coordinate system is a reference framework that defines the position of features in either two- or three-dimensional space. Maps and scenes use coordinate systems to locate and display data correctly on the earth's surface and relative to one another. Allow panning across the international date line in maps.Save a coordinate system as a projection file.Specify the coordinate systems of maps and scenes.This can be reset at any time by repeating these steps for a new location. Your machine will now remember that spot for future jobs. Then click the Set Finish Position button. To change your finish position, go to the Move tool window and use the arrows to reposition your laser head to where you would like it to return to on job finish. By default it will return to 0,0 however this is not the optimal location for some machines. LightBurn gives you the control of where you want the head of the laser to return to after a job is finished. Note that the Finish Position setting is for GCode-based controllers only. If you specify "User Origin" as the "Start From" value, the laser will move back to that programmed location and start the cut from there.

You jog your laser to the position you want your job to start from, hit the "Set Origin" button, and then you're free to move the laser around again. GCode based systems use the "Set Origin" button in LightBurn to do the same thing. Some lasers have an "Origin" button on them (like Ruida controllers). User Origin works almost exactly the same as Current Position, except that the starting location is "programmable". Using Current Position and Job Origin together lets you line up a cut on a piece of material with ease, once you understand how it works. If you position the laser directly over the center of the item you want to cut, the resulting image will be centered on the item. Now the job is going to be cut centered around the current position of the laser head. If you change the Job Origin setting to "Center", you get this instead: Imagine that you wanted to cut this amazing two-circle pattern onto a beverage coaster or a phone case. This represents the position of the laser when you start the job, so the laser is going to move slightly up and to the right from wherever it is, cut the two circles, and go back to where it started. Notice that the green "Job Origin" indicator has moved. In this image, we're starting from the Current Position, with the Job Origin set to the lower left:

You use the "Job Origin" control in the Laser window to tell LightBurn how to position the job relative to the laser. Your job cuts relative to the current position of the laser head when you hit the Start button. In "Absolute Coordinates" these are always in the same place.Ĭurrent Position is probably the next easiest to use. The green square in the lower-left of the image represents the Job Origin, and the red square in the same place shows the Machine Origin. In the image below, the two circles placed in the middle of the work area will be cut in the middle of the machine work area. See Machines without homing sensors / limit switches. If you have a small diode laser that does not have homing sensors, you will need to manually zero the machine. Note: Using absolute positioning requires a laser with homing switches and a fixed origin. Users with small lasers like the K40 will likely find this the simplest and most intuitive option. Anything you place in that area will be cut in the corresponding place on your machine. You choose them in the "Start From" box on the Laser tab:Ībsolute Coordinates is the simplest - The page grid you see in the main editing window represents your machine's work area. There are a couple different ways to tell LightBurn how to cut the project within the work area of your machine. Numeric Edits - size, position, orientation
