Re: Error while generating a circular path?

Granted I use state of the art industrial CNC, but if i want a circle I input G02 X0 Y0 I(radius) J0 and that's a circle. No need to break it down in arcs or segments or whatever. The CAM may be authorized to make 2 arcs maybe, but the rest should be the work of the post processor if the specific NC...

Re: Is Freecad good for 3D printing?

I would add simply that Yes, FreeCAD is good for 3D printing. You can easily generate.stl files and you can also very well control the accuracy (tesselation) of your .stl file. The rest (slicer, printing) will be done outside using extremely potent printing programs like Ideamaker or Prusaslicer or....

Re: 3D Surface - differences between releases

Hi friend,

There's now one more hoop to jump through (the first one being EnableExperimentalFeatures): go to Edit, Preferences, Path and in the last tab you'll have a tick box to enable access to OpenCamLib features.

Happy milling,

Re: Supplemental From Shape (2D) machining order

Is this the part where someone suggests that the PathWB be able to distinguish layers from a 2D dxf file created either through Draft or imported? Probably not. Super glad you could manage to solve your issue. Regarding the PostProcessor you can modify or use every Z retract as a flag for M4 M5. (Or...

Re: Gmsh applied on threaded fastener inside a threaded hole produces warnings

From what i understand of your problem it's not a meshing error. It's a geometry error. The gap between the threaded hole and threaded screw is already a problem in itself. It might be of use to redesign the problem in a simpler way and not using the fastener directly to check other functionalities....

Re: Centering origin between edges or middle of circle

Isn't the Workfeatures workbench perfect for this? Place the necessary datums and bingo. Alternatively the PartDesign DatumPoint is great too. Personally I have a little crush on Local Coordinate Systems (clearly defined in space and all...). And then you use any of the above to Set your Job referen...

Re: multiphysics fem in freecad

but the impact for users is huge and there is no open source tool doing that really! Yes indeed! Advantages of sparselizard over Elmer: you get an extremely concise and readable code without loss of capabilities or speed, so from that part you are not getting lost in 1000 lines of Elmer code and ma...

Re: multiphysics fem in freecad

I know that I am technically "off topic" by talking about this, but since Elmer is the closest multi-physics implementation we have at the moment I have to mention it. I have no information yet on Sparselizard but will check it out. Currently multi-physics in FreeCAD has been initially imp...

Same here, check your mesh in ParaView if you need to ve reassured.

Re: How would I mill this curved face?

I second the advice above. With the 0.19 version you will have a more complete and more robust set of CAM tools. Regarding your specific part, it really depends. with work-holding I would hold the part not the way it is shown in your 3D view, but on the side, so that a simple 2D path with and endmil...
