![]() Measure the distance between the reference point you originally marked and the actual point you marked to determine what offset you need, and enter those values for the Laser Offset.You may need to change the Job Origin setting in the Laser Window. Make sure you have an easily identified point at the job origin. Burn a small dot or intersecting lines at this location.Make sure Start From in the laser window is set to Current Position, and line up the red dot with the location you marked.Mark a location on a piece of material to use as a reference.Adjust the offset value to shift the position of the laser's output relative to the red dot. ![]() If your laser has a red-dot pointer that is not aligned with your beam, you can enable the Laser Offset value to compensate for this when framing and positioning. If your laser output is mirrored horizontally or vertically, move the dot to the opposite corner, horizontally or vertically, depending on the direction that the output is mirrored, and that will correct it. If you have a DSP laser, like Ruida or Trocen, the origin is usually where the limit switches are placed, and will will be the corner the laser seeks when powered up. ![]() If you have a GCode based system, this is almost always at the front left, regardless of the location of your limit switches. This is the origin corner or 0,0 location for your laser. Note that this setting on GRBL & DSP devices does not affect the laser itself, it's just to tell LightBurn how large the work area of the laser is. Set this to the maximum X and Y travel for your laser. This is the working size of your laser bed.
