For instance, a machine with a travel distance of mm x mm and a center origin would require G10 L2 P1 X Y In this image, the origin is at the rear right of the machine. Snapmaker Luban.

Most GCode -based lasers are pre-configured to work with LightBurn, but if you have a less common machine like a Shapeoko, EleksMaker, X-Carve, or Acro system, you might need to make some simple changes to get the most from LightBurn. It is highly configurable, and this is both a blessing and a curse. The "standard" way a CNC machine is configured is somewhat different from the way laser machines often are. Luckily this is easy to change, and easy to switch from one to the other. More recent versions of GRBL 1.

The second is a feature called variable power mode, or the M4 command.

If the entire graphic is one layer 03, for instance , I often get one or a couple of lines that would skip. If I turned that skipped line to another layer 04 , it would then burn that line, but then a different line would skip. It was getting frustrating. The laser would move through the motions, but only the beam would shut off for that particular line or line segment. Often times, on subsequent burns, the same line would skip. So I tried something else today, and I have often converted some of my vector graphics to separate layers to avoid the potential skips that have plagued both my machines for the past year.

Skreelink September 30, , pm 6. Some systems, like Easel or Carbide Motion, may need a different value, so it's a good idea to make a note of the existing setting. I misunderstood your explanation that this occurred with the Illustrator import after 9 successful burns. If the numbers are set properly it would have to be something the pwm is doing.

Trying to understand why it cuts better in the X direction vs the Y direction. With the Sub-layer feature, you can configure count, type of pass, speed, frequency, and more, without duplicating geometry in your design. Did you do this as a line or fill operation? Those can potentially cause burning scenarios. Make Default for All : Your current layer settings will become the default for all palette colors. This topic was automatically closed 30 days after the last reply. Its used for cutting and would be nice to know more about it? Depending on the material there are various mitigation strategies. Tomorrow night I will try the suggested settings more than 9 hours engraving process. Thank you both for your help so far. Not sure if its visible in the picture, but the left and right sides are barely cut through, while the top and bottom sides are cut clean through.
