@schnebeck That would have saved me a lot of time. I didn't see that there was a helixing "method" on the ramp-dressup hidden among the Property-values. All I got to see was this awful zig-zag effect going down. I will need to investigate its code, after my entanglement with all the other ...

I found that the normal Contour Path operation was damaging my HSS tool when cutting aluminium, even with a stepdown of 0.2mm. Those little plunges at the start of each layer sounded pretty bad, even with a very slow vertical feedrate. So I got into the guts and added a helix contour feature onto th...

@chrisb Helix and Drilling (the operations that outputted F0.0000s) don't make sense for 3D printing, so it can only be garbage. The problem with garbage like this is that every single post-processor will need to be debugged individually to filter it out as this kind of unexpected garbage crops up. ...

@mlampert I can't see where the circular dependency is for the values in the SetupSheet. However if all its values were of the type "...Expression" (ie to-be-copied values) there would be no dependency on anything, as copies are made at the construction of each operation. The only compromi...

Amazing what can be done in Python. Almost don't need the C++ for most of the complicated things. This script didn't work in my version 0.18.15481. I had to change line 626 from: self.JobModel = self.JobSelected.Base to: self.JobModel = self.JobSelected.Model.Group[0] Is this a recent change which a...

Thanks for going through those points there. I think this can lead somewhere. I have now done some substantial machining using the *Drill, *Helix and *Contour operations. https://twitter.com/goatchurch/status/1079820982586667009 I have hit a lot of small issues, which don't seem to warrant escalatin...

This is to separate from a discussion started here: https://forum.freecadweb.org/viewtopic.php?f=15&t=33067 I think I have finally got an account of all the places where parameters and values are stashed away for a job/operation. A Job contains Tool, Operations (which contain Paths), Body, Stock...

Some small annoyances to get out of the way: 1) I was looking in vain for an actual spreadsheet matching the icon! Could I clarify in the documentation that there is no such thing as a "SetupSheet", and that all the values can be found in the "Job Edit" dialog? https://www.freeca...

I think we can extend the nester to the Path/Part design workbench, by taking the stock shape as the container, and the Z-flat faces of the bodies that we want to cut out from the stock. I have had a look at running this nester from Python, and it seems to depend on having a set of shapes that conta...

Thanks for the notes. This is amazingly fast response; there must be a lot of people watching. I had a look at AD Fusion yesterday, and its tag feature is more limited (fewer shape options), there is no editing of positions, and it puts tags on the concave parts. So I think this implementation is ah...
