The faster you move longer the overscanning will need to be.The above are real works from NEJE fans. This will allow the Laser to reach the correct speed before turning on. Likewise when accelerating it will start outside the engraving and turn on when it reaches the correct position. This causes a fringing effect on your engraving.īy using overscanning on your layer the laser will move past the end of the engraving and turn the laser off then decelerate. Without overscanning the laser would slow down as it nears the end of the engraved area but because the laser is still turned on the area of acceleration or deceleration will get darker burning because the laser is moving slower in that area. This is necessary to overcome acceleration and deceleration. It allows the Laser to move the past the end of the object you are engraving. This is an important feature then engraving photos or shading an object.
Ignore the disconnected message on screen as it only applies when the Laser is connected directly to Lightburn.This is only a problem if you set up more than one device. Ensure that you have selected GRBL-M3 (1.1e or earlier) for your device when saving to ensure it outputs the correct Gcode format.Once you have created your project select Save Gcode to output your file.While there are many settings that you can use the steps above are the minimum needed to get up and running. Under the Basic settings tab select M8 for Air assist.Along the top line find the Along the top line find the symbol and click on it.Step 3 Device settings Basic settings tab Under Unit / Grids select mm / min or Inches / min as required.Along the top line find the symbol and click on it.Turn off Auto "home" your Laser, (switch will be brown when off), and click Next.Enter the X & Y axis length for your machine and click Next.select GRBL-M3 (1.1e or earlier) and click Next.
When you first open Lightburn it will Ask you to select your Device. It assumes that you are using a Diode Laser. This document does not seek to teach you how to use Lightburn but how to set it up to use with MASSO. When you are happy that the software is what you want you will need to purchase a license for the GCode version of Lightburn software. It is a very powerful software that can be used with Windows, Mac OS and Linux. With Lightburn you can design, edit and create the Gcode which you can send to your MASSO CNC controller. It has a free trial that allows you to test it with your machine before purchasing. Lightburn is a software package designed to be used with Lasers of all types and can be used with CNC machines.
