Well, it seams that Mr. Todd is of the opinion that when implementing an algorithm on the mathematical volumes/surfaces is hard and doing so on the tesselation is significantly easier its best to not bother with the slight increase in accuracy afforded by the mathematical volumes/surfaces. If anyon...

Reading through this, I'm reminded of some comments made by JulianTodd last year and they sound prophetic now. He advised that Path should work exclusively with tessellated models and avoid trying to calculate tool paths directly from the 'real' geometry. Well i would be interested in hearing his r...

I haven't commented yet because other things in my life have been eating up my time and because my math skillz probably aren't up to the task. But I've been following along the best I can. After chatting with mlampert, I think we should merge this PR. Reading through this, I'm reminded of some comme...

That looks great! Nice work

Hi asdaf, There are definitely bugs in the tool table / library. You've hit a couple of them already. If you start by creating an endmill, set the diameter and save it. Then edit it and change the type to ball-end mill, the diameter should take. This is a stupid GUI bug and needs fixing. The tooltab...

A small enagement distance specifically to avoid the issues you raised could be introduced almost silently into the depth calculations without causing all kinds of confusion. i would like to avoid hiding things from the user. We're programmers. Hiding details from users is what we do. If we weren't...

Slow down and talk it through. The current implementation has served us well for a couple years so there's no emergency. Get it right and get some buy-in before changing things. The devil is always in the details and changes like this ALWAYS have unintended consequences. They are also way more work ...

In my mind, that's two different things. I can see wisdom in adding an 'engagement height' as a new concept and using it to generate safer gcode. But until we add such a thing, we don't have it. It seems wrong to misinterpret existing data to force it to fit an entirely different concept.

The chart is good for general understanding but for those who care about trivia or just like being extra picky: :lol: it's ALWAYS possible to move at G0 speed away from the material. ( Z+ in most cases.) In some canned cycles, the system will also move at G0 speed toward the work. For example in pec...

English is also not my first language, but i take issue with this image, as it implies that g0 can be used to rapid dowards all the way to the stock top. This is, in my opinion a bad idea for 2 reasons: It assumes that the stock is touched off perfectly and is not higher then setup in freecad by ev...
