Re: Expert Feedback needed: LeadInOut dressup

The tooltip is "The Mode of Point Radiusoffset or Center" Anyone know what the use-case of this thing is? Again, without a useful argument, I'm inclined to kill it off. The use case for this was presented in the posting https://forum.freecadweb.org/viewtopic.php?p=593094#p593094 but I add...

Re: If parameter is not changed don't add it in post processor?

Hi MisterMaker, I was just reviewing the highlights in the image showing before and after. You highlighted the Z registers as having been inserted for a repeated value, but I see the first value Z36.000 (line 71) vs Z34.000 (line 73) as the follow-on value, and the same at the Z transitions, so I th...

Re: CNC Maschine with built in radius compensation

Hi thomas-huber, If I understood correctly, you wish to program the cutter's measured radius directly into the CNC. Normally, the compensation register is for the difference between the "design value" and the "actual" value of the tool's radius. With that approach, you don't need...

Re: Proposed Console Manipulations

I have now used FreeCAD for just over 1 month, and understand better the workings of the GUI. While my above request is still what I would prefer to have as end-user experience, the current tiling function of the different panels (allowing to pop to larger window, then pop back into the multi-panel ...

Re: CNC stops between G0 moves when adaptive clearing

I know it's been a while, but when I worked with CNCs, manufacturers sometimes had notes indicating a control parameter for the "rapid" servo-positioning "mode": (a) ensuring position registers fully matched the programmed value by static linear positioning guides, OR (b) allowin...

Re: Postprocessor Fagor 8060 working

If I may, I would like to comment on whether post-processors for different machines should be combined or kept distinct. I hope you will allow me to share my experience (as the responsible person in a process development team) outlining requirements for post-processors, and doing machine-tool prove-...

Re: Matrix formulation for rotation about an arbitrary pivot point and normal

Thank you again, Ed. I finally figured out that I was using the wrong value for the angle for the total sweep of the radius on the first horizontal arc. I was using the value of ApexAngle for both, when I should not have. The new value FacetArcAngle contains the proper value to be used. The script n...

Re: Matrix formulation for rotation about an arbitrary pivot point and normal

Thank you, Ed, for providing me with those hints and insights. I will work on incorporating those in my code. To put my efforts in context, my long-term goal is to build on what was already done by another FreeCAD user for simulating the the cutting (and generating the shape) resulting from simulati...

Re: Precision of python scripting objects and printing/reporting

Thank you, heda. It seems that I must abandon habitual preferences to adopt practices that are more in tune with the language's, and the community's, coding expectations. If I want future code adopted by FreeCAD, then I know what I must do. :) As for your coding hint, that worked well, and I can see...

[Solved] Matrix formulation for rotation about an arbitrary pivot point and normal

Trying to finalize a geometry generation script, but I am finding conflicting references and the outputs don't seem to make sense. My expectation is that the 3 points of an Icosahedron face should map onto each other if I rotate those points around the normal axis at the centroid, by 120 deg or 240 ...
