Hi Antonio,

For laser engraving metal and plastic parts, software like CorelDRAW and Adobe Illustrator are great choices due to their precision with vector graphics, which allow for detailed and scalable designs. Inkscape is another good, open-source alternative for similar purposes.

If you require deeper engravings (over 0.5 mm), which resemble milling, consider using CAM software like MasterCam, SolidCAM, or FeatureCAM for better control and depth management.

Overall, the key is ensuring your design software can export to a machine-readable format that your laser engraver understands. If you're satisfied with your current tools, there's no need to switch, but exploring options like Inkscape or CAM software could be beneficial for more specialized needs. Good luck with your project!
