We don't have a purpose written post processor for mach3 yet. I'm not familiar with intricacies of mach3 but starting with the linuxcnc post and adapting it would not be difficult. If you do this, please share it back so we can get it in the repo.

Talking about consistency one thing comes immediately to my mind: the different ways of selecting multiple elements, where elements can be sketches wires, edges, vertices, ... - We have e.g. the selection window in Part->Loft, where we have a left side to pick from and move the selected to the righ...

For the last few months I've been working on a book about FreeCAD. The second draft is finished and I hope to have it complete by fall. The book is aimed at new users from high school up. I make no attempt to thoroughly cover everything in FreeCAD but focus on core workbenches for achieving specific...

Centroid only shows up as the default because it comes first alphabetically. Maybe we should make linuxcnc an explicit default.

I would direct you to other venues for that kind of information. The linuxcnc forum for instance. The parts, as designed in FreeCAD, are drawn to dimension. There's no tolerance in the design. 1mm equals exactly 1mm. The gcode generated from those parts is equally perfect. The question becomes how a...

One time I put *one* unit in using 'in' in a model -- big mistake, the mill tried to raise the quill 17 inches instead of the expected 17 mm. Now that sounds like a bug that must be fixed. I've never seen this behavior. Please send a reproducible example There is a PropertyVectorDistance that you c...

I was wondering the same thing about App::PropertyPlacement instead of App::PropertyVector but I don't know about the deeper implications of that.

Might be worth the experiment

Here's the file with ops set up. I did manually adjust the start depth of the second pocket to avoid recutting the air above.

However, currently FreeCAD cannot mill in a first go everything to the first level as you might have done manually, but mills only the outer border or all the way down to the inner pocket, depending on the sequence of the operations. Not true. A pocket operation that selects the bottom face of each...

Btw: If i understand mlamperts last comment in https://forum.freecadweb.org/viewtopic.php?f=15&t=29667&start=10 correct, the new Champfer OP can do thad without helper pad. Yep. That's a great option for some edge-features like this but not all. You don't always want to clear an area like this with...
