I have my laser "cutter/engraver" moving properly and laser turns ON/OFF. This example code is for a Vector engraving so the S power level is fixed 30, and the speed is set to 700 This particular code was for doing a greyscale image using Line to Line Tracing option so there are varying laser power levels. The Speed setting is the F100 or whatever you set yours to.Īll the S's are the laser power values. Saving the program allows you to edit the code later if the burn was not as good as you thought. Then you end up with something like this example: So when you have your image imported and the settings how you think are ok you can save the GCode by clicking File, Save Program in LaserGRBL. The settings are then inserted in to the GCode when it's generated. The settings can be changed when you import your image in to LaserGRBL. It can have a high speed (mm per minute) setting but if the S for the laser power value is high it will still burn more than if you have a high speed and low power S setting. It's to do with the S setting and the speed your machine moves. So you can use a 2.5 watt laser but only burn lightly. If you are using LaserGRBL to burn then the settings for the laser power are in the GCode when it is generated. Yes you can burn wood with a 500mw, and yes the more powerful the laser the more it will burn.
