Re: Macros for pyramids and polyhedrons

I've been asked by users to add the workbench "Pyramids and Polyhedrons" to the addons. But there's a problem. I've done most of the tasks on "Adding your workbench to the collection" except task nr. 5 : adding the workbench_icon.svg because I've not the required push access Perh...

Re: problem with the finish pass in pocket when milling a b-spline or ellipse

@freman To be clear. I'm just a user who has stumbled over that problem. I was testing shapes based an SVG drawing. And there it turned out that the finishing cut (or the final cut) was NOT carried out on splines and ellipses. I do have a programming experience but only a limited knowledge of Python...

Re: problem with the finish pass in pocket when milling a b-spline or ellipse

@ freman I'd guess that when this is converted to Gcode, as similar test is being done but with <= in place of < Yes, a difference of 0.0001 usually means just that. The difference however occurs IMHO before the generation of the Gcode. I would point in the direction of line 1501 : wires = section.s...

Re: problem with the finish pass in pocket when milling a b-spline or ellipse

@ Freman Hello Thank you. I didn't have problems with parts based on basic lines and arcs or circles. Additionally I've made a new testmodel with circles and I didn't notice any problems. Tested with FreeCAD 0.19 and 0.17 Please post the drawing that is causing the problems and I will have a look at...

Re: problem with the finish pass in pocket when milling a b-spline or ellipse

The short story: I have a proposal. In the freecad source /src/Mod/Path/App/Area.cpp: Line 1406: double zNew = zMin + myParams.SectionTolerance; Change it to: double zNew = zMin + myParams.SectionTolerance + 0.00001; (There are similar lines of code (1370, 1376, 1411) but I've not experienced proble...

Re: Macros for pyramids and polyhedrons

OK, I've added them as two macros.

You'!! find them in the Addons Manager under the names Pyramid and Polyhedrons

Re: problem with the finish pass in pocket when milling a b-spline or ellipse

After more testing ... Forget about the extra info: that error must have another cause. The main problem stays. The program is perfectly capable of building the toolpaths during the pre-cutting operation and yet it does not perform the finishing operation. And this error only happens with certain cu...

problem with the finish pass in pocket when milling a b-spline or ellipse

Hello, I think there is a problem with the pocket function when milling special curves like ellipse, b-spline, .... (With ordinary shapes with straight lines and arcs the function works fine) The problem occurs with the final cut: - with a finish debt > 0 the finish operation is simply not carried o...
