I work for a company that it's developing a multi function XYZ machine and I'm developing the first module now: the laser cutter. The laser works well but I'm looking for a software to convert image to gcode (with grayscale). The features that I'm looking for are: 1. Z axis support (for height configuration) 2. PWM for laser power changing according to grayscale pixel value 3. Support for severaby ricardo.nunes - Laser Cutter Working Group
