While performing an engraving job, the laser head must constantly accelerate and decelerate to follow direction changes. M4 Dynamic Laser Power Mode (new in grbl v1.1) This can lead to more consistent cuts in more difficult materials. This provides better control of the laser state. M3 Constant Laser Power ModeĬonstant laser power mode simply keeps the laser power as programmed, regardless if the machine is moving, accelerating, or stopped. These enable two different laser modes that are advantageous for different reasons each. The laser is enabled with the M3 spindle or M4 spindle commands. (See grbl configuration) 2) Laser options Please note that LaserGRBL will command these values, but it is possible that the machine does not respect them because for example it is limited by its maximum configuration speed. (Is it possible to do little adjustment at runtime via overrides) If your job is coming out too light or too dark you can slow down or increment the requested job speed.
Border speed is the speed used for border pass (or cut) by the vectorization tool.Filling speed / Engraving speed is the speed at which an image will be filled by laser moves.From this dialog you can set final image size and offset as well as laser speed, power and laser mode.
