GS High Level Overview

GS High Level Overview

The Grayscale high level overview has two parts to it:

  1. Laser tool calibration.
  2. Image Settings.

Laser Tool Calibration

The laser tool calibration process (steps) involves finding the right combination of laser power (50% or 70% or 100%) and feed speeds…for burning a 16 shade GS pattern.

This GS pattern will start with a black square and progress with lighter and lighter shades until the last shade (the 16th square) is ‘white’. The last ‘white’ shade is really the color of the wood. I put single quotes around the word ‘white’ because with woods, there is no true, pure ‘white’ color.

Photo of the Pattern

A photo must be taken of the burned pattern and loaded into BCL so it can sample the actual color shades, as burned on the wood. I use my smart phone camera to do this. After taking the picture of the pattern burn, I connect a USB cable to the smart phone and then, using my windows file manager, I can access the picture and load it into BCL.

Once the laser tool has been calibrated, you are done with the laser tool. This is a one time task.

Image Settings

Part two of this process involves image settings. You could make an argument that image settings is more important than laser tool calibration. Why? Because there are so many different kinds of images/photos. Some are better than others. Some will engrave with out-of-this-world results and some will never engrave well because they don’t have a good internal file structure. That is, a good resolution or a good pixel count, etc.

Image Settings will allow you to adjust the image settings for a given photo to get better burn results. So you can adjust the brightness and/or the contrast for example.

Laser tool calibration has its own window and image settings has its own window.

Laser tool calibration settings are saved into the laser tool itself.

Image settings are saved into the tool path file, if you elect to save a tool path. If you adjust the brightness and don’t save a tool path file, your brightness setting won’t be saved for the next time. While this may sound odd now, once you start to use the engraving features, it really does make sense that it works that way.
