Glad to hear of your success with solving the crashes. We sure enjoy FreeCAD and think you will as well. May I state that you probably will not need to update your nightly too often. A lot of the commits that occur are small incremental fixes or improvements, not major features. I'd say once a month is a reasonable frequency - only an observation.
Nice! Cat is out of the bag now, Sir. Should your fingers get twitchy or you find and occasional afternoon would be a bit more challenging with some coding thrown in, we'd be glad to have another developer for Path/CAM.
Welcome to FreeCAD and the Path/CAM forum, where the paths are many and the chips fly freely.
Also, I'd ask that you please perform a final act of closure for this thread by returning to your original post in this topic and editing the title to include a '[Solved]` or `[Fixed]` tag.
