The S-Value Max setting in LightBurn must match your controller setting, or you'll either get not enough power output (if LightBurn's setting is lower) or very small power numbers will set your laser to full power (if LightBurn's setting is higher). GRBL defaults to 0 to 1000 for newer versions of GRBL, or 0 to 255 for older ones. Smoothieware typically uses a value from 0 to 1 and supports fractional numbers in between. This setting is the number that corresponds to 100% power in LightBurn. GRBL and Smoothieware use the S-Value (spindle speed setting) to control the PWM power output to the laser. If you do not set this value, LightBurn will use the same speed as the G1 moves. This can save significant time.Ī note for Marlin users: Since Marlin treats G0 and G1 moves identically, this value is used to specify the speed for rapid moves. With the Fast Whitespace switch enabled, LightBurn will boost the speed through blank areas to the speed you indicate, if it is faster than the current engraving speed. If you are engraving slowly to get a good burn, but the image contains a lot of empty space (white space), this takes a long time. When engraving an image, LightBurn normally moves at the same speed across the entire image. See the help for Scanning Offset Adjustment here.
Scanning offset is useful when doing raster or vector scanning at high enough speeds that delays in your power supply cause the firing point to be a little behind where it should be.
If you have a DSP laser, like Ruida or Trocen, the origin is usually where the limit switches are placed. 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 or 0,0 location for your laser. Set this to the maximum X and Y travel for your laser. This is the working size of your laser bed. After initial setup, you can access device settings under the Edit > Device Settings menu.
