Can you share details about Blender CAD/CAM capabilities? I have a CNC router (carves 3D shapes into wood), and exploring what tools can help with that. I keep hearing about Blender's CAD abilities - I don't know Blender well, so I haven't jumped in there...

Blender is not the right tool for that. I think you'll be happier with an actual CAD tool like Fusion or FreeCAD.
