Re: LibLathe - Lathe Path Generation

I agree. In concept, I would assume that any model would require alignment so it is aligned—and centered on—the z axis, in the job setup. As you mentioned, with user option to reverse between +/- z. Broadly, most job models milled in Path are generated in FC, so in many cases, this isn’t an issue. A...

Isn't the axis of rotation always around the Z axis?

The horizontal Z-axis on the lathe strikes me as a local coordinate system that job models are translated to align. What is different about this compared to machining jobs that require aligning the model to face toward +Z?

Re: thread milling?

I'm in no real rush, but figure it's a good capability to have in FreeCAD, so I'm glad you've taken a pass at it. Hope you're back up and milling sooner than later!

Re: thread milling?

I'd forgotten about it, but I'm pretty sure you'd been kind enough to mention it before. Hope you're well Dan.

Re: Dressup Tag bit compensation has an error

Hi Markus, Sorry, I missed your reply until today. I get you on all points. I didn't actually do anything with tool type--other than to point out that it's relatively straight-forward to generate, and to show in a sketch how the compensated paths for the meaningful tool types would work. I agree wit...

Re: Dressup Tag bit compensation has an error

Hi Brad, I dug into the PathDressupTag.py and I made some changes,, but I'm not sure how to try it out in place of the comiled version. I know I got through the syntax errors though... I saw what you were doing, and kept the output of TagSolid.__init__ the same--Cylinder, Cone, or Sphere for degener...

Re: thread milling?

So, there are various ways this is done, including what you describe, which uses a clutch to drive a tap for internal threading. Generally they are pricey, by hobbyist standards. $500-$1000 range likely. https://static.grainger.com/rp/s/is/image/Grainger/2ZAZ1_AS01?hei=128&wid=128&$adapimg$= The met...

Re: Complete loop selection from two edges (P, L) bug

If this had come up before so many 3d milling features were added, the simple solution would be--as you mentioned--to ensure the selected edges all are in the same plane, but that might not be a good fix at this point...
