Re: thread milling?

Rolled threads are stronger than tapped threads. Bicycle spokes have rolled threads for that reason. The thread o/d ends up bigger than the spoke diameter since nothing is removed. Often, special high tensile bolts , like for con-rod caps are rolled threads. High quality, precision ball-screws are r...

Re: thread milling?

Hey cool, it works. I'll have to try to knock up a test tool.

Maybe at least this would be a good way to start a thread good and vertical , cut half the depth and then finish by hand with a proper tap.

Re: thread milling?

The threadmill operation will require a threadmill tool. This is brand new stuff so there isn't one in the example toolbits. It looks like phpbb won't let me attach a toolbit (.fctb) So I can't give you mine but here's the contents. { "version": 2, "name": "threadmill"...

Re: thread milling?

Interesting, I'll try to find time to look at this later. I would really suggest you get set up for doing a full local build. Getting a clone of the source code tree and building is relatively simple. It just means pulling in the relative devel packages ( header files ) for your platform. Use qt5 De...

Re: Path Profile Faces: 4th-axis integration

this one allows me to use the 3/8" endmill that I want to use in real life, where the pocket operation doesn't allow this. Look at extensions in the pocket set up dlg. Deselect "extend corners" and then you can select to edges to extend . That should allow you to "pocket" b...

Re: Path Profile Faces: 4th-axis integration

Hi Russ. from my limited knowledge of the 2.5D code base it seems the problem is the lack awareness of the model. There faces are treated as wires and edges and the area is projected downwards on the the z plane and the normal is upwards. If you want quick hack, how about a boolean property "pr...

Re: Path Workbench Repairing an Operation Moved Out of the Job

Thanks for that overview. I've been digging into the code and it looks like most of this is happening in TreeView.cpp , that is probably where the structural problem lies. Since the things being manipulated may have specific inter-relations dependent on which WB created and controls them, there shou...

Re: Path Workbench Repairing an Operation Moved Out of the Job

Ah, of course. So there needs to be some checking in the on-drop event.

Does DnD work correctly elsewhere in FC or this part of a broader issue?

Re: Path Workbench Repairing an Operation Moved Out of the Job

this should be done is... far far away from anything Path related ... it should better be be controlled by Path workbench itself, and not by something outside. Sorry, I'm not following what way you think this should go. By pointing to the code in TreeView.cpp I was highlighting the existence of the...
