Hi everyone! It's my first attempt to model CNC router in CAD software. Work still in progress, but CAD pretty much done.
Router made of 10 series fractional aluminum extrusion profiles and aluminum flat stock. Base made of 2 2"x4" side profiles and 4 2"x2" cross members. Gantry made of 2 2"x2" profiles that tied together with 1/2" aluminum plate. All sizes and shapes made to fit widely available flat stock.
Fasteners are mix of metric and imperial threads just because all linear motion hardware use metric, but fractional extrusion wants imperial. You can use all metric, but it will require some additional work.
Project created in FreeCAD Link. You can find latest releases here: https://github.com/realthunder/FreeCAD_assembly3/releases
Also you need to install Fasteners workbench: https://github.com/shaise/FreeCAD_FastenersWB
