From the developer:
JVElaser creates a G-Code, compatible with most 3D Printers, equipped with a laser module (glued, strapped or attached in any other way). It can open a variety of formats, parse them into layers and produce comprehensive G-Code to burn them using your 3D Printer. A wide range of configurations is available, which could completely customize the G-Code produced, both in terms of the supported printers and in terms of output preferences.
