Start Y : - Y value to start image from.The laser will start here and move in the positive direction as it scans.These X,Y points correspond to the top right of the image. Start X : - X value to start image from.Note that if lines start to overlap you might need to bring your power down slightly.

You can try to defocus your laser to make thicker lines for shorter overall total time, but you will have to increase your power. 0.1 leaves visible lines, which is kind of a cool effect. For my laser this is 0.05 though I can usually get away with 0.075 because its faster. You need to make this small enough so there aren't visible unburned lines.

Scangap : - This is the distance between lines which is a function of your laser spot size.

Beyond that you will probably see pixelization. If you make this larger you can attain faster speeds, but at the price of some detail loss.

Horizontal Resolution : - mm between pixels.

Height (width autocalculated) : - set the height, the script will autosize the width.

Overscan Distance (prevents twang from showing) : - This sets a 'blank' distance before the start of the line to give the belts time to settle down and the motors to reach constant speed.

You will need to find this speed, and note that the power levels will need tweaked if this speed is changed. This is usually limited by the commands per second rate of your firmware, you can go faster from an SDcard than over USB.

Scan (cutting) Rate : - Speed to move while lasering.

Travel (noncutting) Rate :' - Slewing between places speed.(TODO: preview the image with this level hi-lighted)

PNG images should have white at 255 so 254 is a good value. In a JPEG the white level probably contains some compression artifacts so you might have to go down to 252 or so. Skip over values above : This defines the white level.Usually this is the bare minimum that your PWM board will respond to. Laser 'Off' Power : - This is the laser power that will not mark the wood at all, even if it just sits there.Laser Max Power : - This is the laser power that corresponds to BLACK.Laser Min Power : - This is the laser power that corresponds to WHITE.Add areas that are above the white clip boundary to preview where skip-overs will be.Finish calibration script (currently left dangling who knows what state its in).Change to relative coordinates for ease of fine positioning.Generated bounding box code at start of print.
