- When you need to get square corners on pockets, using a very small toolbit might be pretty difficult. Here is a video with tips for making it fast and prevent breaking the toolbit in FreeCAD 0.22. You will find a lot of optimization methods that you can use in other scenarios, too.

Great stuff again !!
Your content is on the money with the cam/path workbench ..it’s the best I’ve seen by a huge margin .. the workarounds are key..
The freecad devs should watch your vids as you are pointing out the limits/flaws in the path/cam workbench that need to be addressed…
thanks again!!
Thanks! It makes me very happy to hear such kind words.
I know of a few that do watch my channel, so let's hope for many improvements in the future
great stuff. love the attention to detail
Thanks!
I watch your videos with 0.7x speed 😁 otherwise I am lost....
Thanks for letting me know. But I hope that at least that way they are still useful
@@opensourcecnc Yes your content is very informative! Try going slow and use a cursor with yellow circle because you drag the mouse too fast and then it's lost 😁
love your videos. Although , you always sound like your'e about to threaten us with some mafia stuff
Thanks! Glad you like them. We don't talk about the other thing... ;)
Thanks
Glad it was helpful
First very nice video.
But of course, there are differing opinions... I would have used an adaptive tool path, with a quick profile for clean up, then followed up with a "rest operation" using a much smaller bit. You say "adaptive tool path" take to long ... is that in computing them or running them? The idea I believe is to helix into full depth, then mill with a longer portion of the bit ... net result is a quicker and more bit efficient (bit stays sharper) cut.
What are your thoughts and concerns?
Thank you!
On a rectangular surface such as this one, the pocket is way faster both at computing and at running. Also, on a i7 8750, after 5 minutes of computing the boundary dress up for the adaptive operation, I had to force close FreeCAD. Of course there are more ways of doing things, each of them with advantages and disadvantages. The adaptive is, indeed, good for extending the toolbits life. It is especially useful when milling metals. On wood, as long as you don't burn it by setting too high rpm, there's a higher risk of breaking the bit using the adaptive than to dull the tip by using too small layers for a pocket operation.
About the "rest option". It is a great concept, but it works acceptable 2 out of 10 times, for now. It will probably get better over time, but now it's just a matter of luck.
@@opensourcecnc I have to ask what version of FreeCAD you are running. I use 0.22 as my daily version, and I don't know that I have seen issues with either. Have you submitted bug reports?
I just left a FreeCAD meetup last week and 0.22 is about to become a release candidate in the next week or two. Both of those features are queued for version 1.0, so if there are bugs, please report them.
@@carlslater7492 I use 0.22, too. I haven't submitted bug reports, my last few experiences (a long time ago, I have to admit) about submitting bugs were very bad. I just gave up
Btw, I remember you asked me about the grbl post processor: please set the default for drilling to automatically translate the instructions, it's really annoying to have to manually set a parameter in a quite deep place in order to not have errors when sending the code to a grbl controller.
