Ideally I will soon be able to have something other than machining pentagons in plywood to talk about in weeknotes. FreeCAD CNC: CAD and CAM workflow Januby wayofwood - 2 Comments. No 3D printing or CNC milling system can take FreeCAD files directly. I’ll also need to tweak the postprocessor slightly to iron out a few bugs. Controlling the degradation or loss of accuracy.

The next step is to complete cuts for a full model assembly and write up the FreeCAD process for the DoES wiki for others to use. We can now generate models and toolpaths from scratch and from 2d vector files.Īdrian and Nikki were treated to me beaming and hugging a pentagon of wood, and to be fair were both polite enough to humor me in this. I am now happy to report that, after a fair amount of trial and error I have separated the problems with FreeCAD itself and those relating to the post processor generating paths for our specific CNC machine. I’ve certainly been found imitating Munch’s scream as I’ve tried to navigate the various workbenches and post processors invloved. I may, in moments of weakness, have coveted my neighbour's Fusion 360 licence along the way. FreeCAD is the natural (only) open source CAD choice for MCQN and other users of the DoES space. MCQN are supporters of open source, this feels like it’s probably a separate blog post at some point. The task that is consuming all my time at the moment is using FreeCAD to generate toolpaths to CNC mill the base for Acker’s Bell. FreeCAD includes a modern Finite Element Analysis (FEA) tools, experimental CFD, BIM, Geodata workbenches, a Path (CNC) workbench, a robot simulation module. It’s Chris on the weeknotes, just as soon as I’ve brushed off all the sawdust I’ve been generating.
