I've recently started to learn FreeCad and I've finished my first project.
Both CAD and CAM was done in FreeCad 0.18.
A little about the design process:
- All parts in individual files (also assembly and CAM)
- Assembly using a2plus
- Used a Macro for parameter workflow. (Filename of the parameter sheet was changed, in the macro, from "Settings" to "p" for less typing.
Since the parts are in individual files, the parameters have to be changed across all "p"-sheets in the individual files.) - The paths for CNC milling were done with a 4mm bit, 12mm OSB and the zero point set on top of the sacrificial layer (not on top of the material!).
- The shoe rack was designed to be glued, but ended up being screwed together with 3mm screws, 20mm long with a torx head. Adding holes or shallow pockets in the CNC files for the screws would help in screwing them in in the right place.
- Do the whole project in one file; Pros and cons?
- It would be neat the have a gcode streamer integrated in FreeCad for a full package; CAD-CAM-CNC. Inspiration: old USB workbench
- Get to know the assembly workbench better. Not so easy to keep track of the consstraints, and things break easily for a beginner (looking forward to the official release of 0.19 )

I've built the CNC myself, with help from this project: Fabricatable Machines.
