Profiling.
Regular profiling works by selecting a face. Simplest cases work well but many of the options don't work at the moment. Particularly troubling is that the user can't select which side of a face to profile. So if the face has a hole, the profile will always select the outside edge of the solid and the user can't select the edge of the hole.
Pocketing.
Pocket operation isn't really useful yet but Is functional as a demonstration. Most options and parameters haven't been enabled yet but I've been able to produce a crude tool path.
libarea integration. Libarea is the profiling and pocketing operation used in HeeksCNC. It's stable, fast, and is license compatible with FreeCAD. Dan Falck has integrated libarea into Path so it's automatically installed with FreeCAD. (DAN: you can probably give a much better summary)
libarea profile
operation partially working. Instead of selecting a face to profile, the user selects individual edges. This works for individual contiguous edges but not for circular edges or multiple disconnected selections.
libarea pocket. Planned but not started.
Post Processors.
Roland Modela MDX - user jonner working on this.
Maho CNC - user chrisb working on this and has done some work to make the post processors customizable by regular humans.
Other Integration
microelly2 prrvchr is building a workbench to communicate with an arduino via PySerial USB. This will be useful to stream GCode from Path to an external device.
Projects and blogs:
Even with Path still limited in functionality, I was able to make a simple project.
One small correction, it was user prrvchr that started the PySerial USB work.
