Sets how many times the laser will run this filled shape. It works, but it's mostly useful as a style option, and not recommended for general use. Scanning at non-90 degree angles is "emulated" using normal cutting moves. Horizontal and Vertical scanning is supported natively by the hardware, and it will automatically handle over-scanning beyond the sides of the image to get the head to full speed before engraving starts.
If you have a DSP controller, we do not advise using angles that aren't a multiple of 90 degrees. Setting this to 90 will scan the laser vertically over the image, progressing from left to right. If you set this to 180, the laser will scan the image from top to bottom. Normally 0, meaning the laser will scan back and forth horizontally across the image, progressing from the bottom of the image to the top. Lines per Inch ¶Ī different, often more intuitive way of controlling the line interval, or spacing between rows. Line Interval ¶Ĭontrols the spacing between scanned rows, and indirectly controls 'Lines per Inch'. If you do not see this setting, your machine is likely a DSP controller and handles this automatically in hardware. If your machine has low acceleration or you see darker burns at the sides of your fills, you may need to increase the amount of overscanning. When enabled, adds extra moves to the beginning and end of each line to give the laser time to speed up before firing, and slow down afterward. When enabled, runs a second engraving pass 90 degrees rotated from the first to ensure a consistent and thorough fill. Depending on the type of laser, enabling this can save significant time on long engraving jobs. When disabled, the laser will engrave traveling one way, then return to the start of the next line, not engraving the return pass. When enabled, the laser will engrave in a side-to-side sweeping motion, engraving in one direction and again for the return direction. Fill mode will fill in closed shapes but not open shapes.
We've updated the terminology to make it easier for new users.įill mode permits you to instruct the laser to scan line by line and fill in the shape you want, similar to how a paper printer works. In older versions of LightBurn the 'Fill' mode was referred to as 'Scan'.
