Oh wow, that,s freaking amazing.

If the Slicer works well, I wonder if/when we'll get a core r theta voron.

That could be my next printer.

Btw I assume this is patented to hell, but Voron wouldn't need to care right? As they don't intend to profit?

The mad lad GNU V3'd and ~~fully open-sourced it~~

And his slicer here

Slicer is not FOSS. See issue 1.

Thank you for the correction! I only read untli gnuv3 but the second line of the license excludes sale

GNU is pretty common, I'm a fan of this for the hardware, I hope Voron latches on. However, I meant that the slicer repo has no license at all.

License was added 17h ago, but there's a typo in the file name.

[–] [email protected] 1 points 2 weeks ago

Nice, I put that in the ticket. Once it's updated I'll edit my comments.

If the Slicer works well

I think this would be the biggest issue.

I had a bit of experience with 5 axis machining and the programming of it is far from trivial.

3 axis is really easy to automate, the paths are quite straightforward, especially for 3D printing when you go layers by layers.

As soon as you add a 4th axis nothing is straightforward anymore. You have a high probability of collision between the extruder and the workpiece and now instead of having a single mathematical solution on how to go from point A to point B you have multiples options and no "right" option, it all depends on how the machine is built and the shape of the part.

Yup. This is one area where machining and machine movement is still an art. It can be scienced but it's expensive to model a machine that well and CAM software still needs a lot of handholding beyond 3ax moves. That will eventually change, I expect someone will slap some 'AI' into CAM. I wonder, however, if it won't actually require something close to general AI for real world utility.

And if they put a license on it: https://github.com/jyjblrd/Radial_Non_Planar_Slicer/issues/1

Or, if someone comes up with an alternative.

[–] [email protected] 1 points 2 weeks ago* (last edited 2 weeks ago)

Not necessarily the case, but I'm sure some slight mods would be all that's needed.

Edit: hardware is GNU https://github.com/jyjblrd/4-Axis-Polar-3D-Printer/blob/main/Licence

As for the software, please pile on to this issue: https://github.com/jyjblrd/Radial_Non_Planar_Slicer/issues/1
