Yeah, I chatted with @mlampert about the break. He’s already fixed it. We just have to wait for the next nightly build to be compiled and posted.


No, Sir. Hang for a few days until the next nightly. – Or, build from source!


I have a GH repo. I have been working on these scripts to keep with the ongoing pre_0.19 progress. When the current PR 2231 gets merged, I think I’ll take a moment to make a set of scripts for the 0.18 stable users. It shouldn’t be too difficult - so I think… :unamused:

Thanks for the feedback and support.

Hi,

testing the code linked at the top of this thread, I do not seem to be able to add a new job :

19:32:08    File "/~/freecad-build/Mod/Path/PathScripts/PathSetupSheet.py", line 253, in operationsWithSettings
    for prop in value.registeredPropertyNames(name):
19:32:08    File "/~/freecad-build/Mod/Path/PathScripts/PathSetupSheet.py", line 294, in registeredPropertyNames
    return [OpPropertyName(name, prop) for prop in self.properties()]
19:32:08    File "/~/freecad-build/Mod/Path/PathScripts/PathMillFace.py", line 299, in SetupProperties
    setup = PathPocketBase.SetupProperties()
19:32:08    File "/~/freecad-build/Mod/Path/PathScripts/PathPocketBase.py", line 139, in SetupProperties
    setup = PathAreaOp.SetupProperties()
19:32:08  AttributeError: module 'PathScripts.PathAreaOp' has no attribute 'SetupProperties'

I have been able to test 4ax paths in a job I created before dropping the 4ax python files into my build tree, built from master yesterday.

Is this the latest version?

Also , I think we need something like the boundary overrun you put into 3D surface. It would not be good to plunge down ( at 45 deg ) and cut with the full tool width. I would need to use a large "pass extension " of say 6mm to cut with half the tool width ( as chosen in 50% step over ). But if I do that I don’t get a path. It’s bounded by the edge of the selected surface and the tool does not fit. :frowning:

I would also like the over run to ensure it machines up to the ends. I can always lie to FC about the length in this case but the boundary overrun feature on 3D is very useful.

Hello to everyone.
I’m learning freecad 0.20 for the first time, I didn’t open 4 axis rotation, I read and studied the instructions. Where am I doing wrong? can you help me?

There were some difficult issues, and the 4th axis rotation has been removed from version 0.20. It will probably be back at some time in the future.

Thank you for the reply. It would be very nice if a working 4 axis freecad is added. I wish success to everyone working for freecad.

Please give link do download all 3 files -
like written in instruction - https://wiki.freecadweb.org/Path_fourth_axis
Thanks

If I get it correct, the 4th axis has been completely removed from FreeCAD and the py files are no longer available. Right? I couldn’t locate the “Enable rotation” option in the profiling operation settings in V0.22

Evening.
Correct. There might be some residual code, but by and large the 4th axis feature and related code was removed by 0.20 or 0.21 release.

Cordially,
Russell

Read the first post in this topic.

UPDATE: 2020-10-06
Since the last update above, there have been a few additional improvements and fixes to the 
PathPocketShape module pertaining to 4th-axis. The scripts mentioned in the intro above are 
removed from this post and the master branch contains the most current version of the 
PathPocketShape module as related to this particular thread.
