Pack curves on sheet example

New release!

What is new:
  • custom cutter shapes. With exact mode, only convex are supported. 
  • limit curve - you can now limit any operation with a curve.
  • limit curve and ambient have now an option, whether the cutter stays inside completely, or reaches the limit with it's tip.
  • Pack curves on sheet - this helps a bit to save material. The algorithm is slow by now, but provides relatively good results
  • Code for this version was completely reorganized and there are many internal changes. 
  • Please test and report any bugs you encounter, there might be some tricky things.
  • some more speedups in both modes.
  • Lots of bug fixes
  • Big part of work for n-axis was done, but it is not visible in UI. I cannot test the code, so I don't want to release anything. also other things are wip.
    limit curve used on an operation 
  • All the code was separated into libraries. I wanted it to be more readable, and also would like to invite more coders to join.
As always, big thanks to:
as always, thanks to:

  • Bernhard Braun and Giovanni Bianchessi for linux & mac builds
  • Gaël Rosset for extensive reporting of bugs
  • everybody who posted feedback or donated
this help is essential for the project, I don't have time to test everything properly, and donations help me to save some extra time.

Also, new tutorials coming soon! and more surprises ;)

List of donors update

I haven't done this for several months - going through all emails, writing down names, and checking if the people wanted to be actually mentioned. I want to apologize for the delay in publishing the donations, I very much appreciate all the donations.

Also, all your donations are rewarded with my work. I spent a lot of time developing new version, but things are still not stable enough to make the release.

Good news is - the list is now large enough that I had to move it to a separate page on the blog. Also, donations towards open-sourcing the bas-relief addon are halw-way there, so someday in winter I expect the target could be reached.

Blender CAM 0.8.0

Let me present you the new version:

new features:

ramps with parallel strategy
- new strategy - curve to path. Enables to tweak paths manually.
-support splitting of large files. This is a machine setting. Splits into files always after a limit of operations per file is reached.-files can be exported now after computation, e.g. if you only change feedrate. This is also faster when you try to tweak your settings.
-operations now can start in the +z or -z area, this was requested on the forum.
-improvement for ramps - these now work with bridges, and are enabled for more strategies.
-experimental feature - more outlines for cutout operation. Is useful for making more space for chips, or to make more space around the piece because of shank. Doesn't support bridges nor sorting!-improved ramps, now work for almost any operation. They now work as zig zag for non-looped paths, so that the cut starts at the beggining of the path. works also with bridges for cutout.






-print progress in the operations list, rather than in header.
-waterline works a tiny bit better.
-if loading files from older files, you need to switch to blender CAM in the top header.










slicing
-basic slicing of objects, for cutting 3d objects from plywood. Just start of this, your ideas are welcome!













optimization:
-new library called Shapely can speedup pocket operations calculation up to 20X, and makes all offseting of 2d paths faster. Shapely gets installed similar to Polygon and numpy.
-many small optimizations made generation of large files about 35-30% faster.


fixes:
-fix pocket operation missing small rest spots, this happened if stepover was larger than cutter radius.
-drill paths work with object groups
-brought back some panels that went missing in last version
- a lot of small fixes




some little tools accessible through operator menu:
-boolean operation for Curve Objects-object silhouette offset, works for curves and low-poly meshes

background work:
- lots of code reshuffling, improvement in readability, so more coders can join the project
- start of testing framework
- starts for some new strategies.

Big thanks go to everybody:
-Giovanni Bianchessi, Bernhard Braun for doing Mac and Linux version 
-everyone who gives feedback and gives images to the gallery, or contributes in any other way
-everyone who donates money
-the people who started contributing code(which will hopefully be in next releases, but I am so happy about this, I have to mention it already now ;)

Today, not sure how,
the access privileges to the download files were changed. A weird thing on the drive... Because I wasn't even online during the day. I changed the access rights back to everyone so downloads should work again.

moving codebase to github

today,
google code announced it's quitting. I have to move my projects,and as some people and also google suggested, the target place is github.
The new repository will be here:
https://import.github.com/vilemnovak/blendercam

I will also try to carry over commit rights somehow.

With this, I want to say big thanks to Google for hosting the files at least for some time. Sometimes, this seems like a normal thing that you get hosting for free,  but I'd say it definitely isn't.
so, thank you , Google.

This is good news for everyone I hope,
the target of 2000 Euro has been reached in approximately one year of time.

BIG THANKS to all supporters of Blender CAM. The donations definitely helped giving me time for improvements and fixes of Blender CAM in various areas, so yes, all of you out there really helped making this software what it is now.

I hope everybody enjoys the addon.

I hope the user base of the software grows even more in the future, as well as group of people who contribute code and help making Blender CAM better and better.

and yes, the addon can be found in github repository:
https://github.com/vilemnovak/blendercam/tree/master/scripts/addons

and will be part of the next release of course.

several new tutorials.

After a long time, finally I have time to devote to Blender CAM too.
there are a few new tutorials on various aspects, the target is to do very short tutorials for single features, so users can watch specifically what they need to learn, sort of a documentation in the form of videos.
Also, I created a youtube playlist for my and other users tutorials. I will add all tutorials I find on youtube to the playlist. BIG thanks to everybody for creating the videos!

Did you create a tutorial and I didn't link it - let me know!

Blender CAM 0.9.0 release

Finally, a new release!

I know the waiting has been long, and those who were in need of the updates, started allready using the version of Blender CAM from github.
There are many fixes, and many improvements, and also, many new features

this list is not really showing pictures, and also not everything that is in the release, but now, there are more people cooperating on the docs so I hope, the pictures will make it soon to the wiki pages which now grow quite fast on the Github wiki: https://github.com/vilemnovak/blendercam/wiki
big thanks for the wiki go to Jeff Doyle,who started this new documentation project.


larger features

  • Polygon library was replaced with shapely library completely. This was a huge task, touching almost all areas of blender CAM. 
  • OpenCAMlib support by Karol Suprynowicz
  • manual bridges placement - now you can define bridges with a group of curves.
  • auto bridges placement was improved
  • medial axis strategy - you can use this for V-carving and Ball-carving(not sure if that's the right name, but enables you to use the ball cutter for the same task).
  • projecte curve strategy - this is a complex strategy that enables undercuts. Some docs will be needed.
  • Intarsion tool modifies curves to be suitable for intarsion - the resulting shape can be cut inside/outside and will fit.
  • Overcuts tool - this is experimental, adds simple overcuts to the curve object, good for fast setting up of slots. 
  • several new postprocessors, most of them by new contributors!
  • 4 axis code is enabled in experimental features, but it's still heavy WIP, and is released mainly to get more people communicating about it!



small features:
  • experimental features can be switched off in addon preferences.
  • curve remove doubles operator
  • Denver Hull commited a patch which adds operation start-stop points and fixed some unit problems
I probably forgot a lot of what was done.

BIG THANKS
to all contributors, to people who communicated on the forums, who helped by donating money, to anybody using blender CAM :)

and SORRY to those I forgot to mention here. And to those to whose e-mails I forgot to reply...

Enjoy using BlenderCAM and stop by on github on the forum to let us know about bugs or your ideas.

Since I now run the BlenderKit website, I have no time to maintiain this blog for many years, but by now I wanted to keep it for sentimental reasons. Have a great day everyone!
