      @nitrofreak Thank you for the video links, those are interesting samples what is possible. I think the sinusoidal discussion is only the "tip of the iceberg", the problem is, that the drive movement planning should be flexible for all drives, not only for the extruder. Maybe the current firmware extended by the possibility to define algorithms between the driver movements as dynamic parameters (e.g. G-Code at the beginning). E. g. if the heatbed is to be pivoted and is a hexpod, the movements will be nonlinear and complex.

      Problems aside, I am sure an open software community can develop the same quality as commercial firms. There must be a driving group of people (or one person) however who are motivated enough to implement the solution. Maybe we can start with such an effort here with the enhanced Duet 3 capabilities.

      If you look into the kernel of algorithms, they are in general very short, e.g. for Delta, for sinusoidal etc. in the different firmwares, so implementing is not a big effort. A correct model of behaviour is the most important point to start with.

        I just found another example of non planar printing all the way back from 2014. It seems to do the same thing

          I am thinking about whether Delta has advantages printing rapid changing Z. Cartesian, CoreXY, Prusa, Ultimaker are designed to print layer after layer, whereas Delta prints Z with 3 actuators, this may be an advantage in the case of non-planar prints. Especially because some of the Z layer printers have backlash when changing from move-up to move-down and vice versa.

            If David implements a 6 axis delta firmware, it will definitly be my next 3D printer! For now, I'm working on my 2 axis tilt bed in order to print portions of sphere (https://forum.duet3d.com/topic/10934/5-axis-3d-printing).

              @NitroFreak Thanks for the videos. I can add diabase to the list (https://www.diabasemachines.com/home) they use Duet to achieve 5 axis but in a different way.

              More generally if the slicer was able to output X Y Z U V W, where U, V and W are the other three axis (e.g. a tilting/rotating bed) then there is no change required or special kinematics. If you want X Y Z A B C where A,B and C are the tool head rotations, then also no issues in RRF.

              What do you mean by "sinusoidal G2/G3 computing", in this case? surely to implement G2/G3 in this case you would need to define an arc center in each axis that the arc would move on?

              In general tool path generation is going to be an issue. Not just the path in 5 or 6 axis but also a path that avoids collisions with parts of the object already printed.

                This is really cool!
                Wonder if it wil make it to the home/hobbyist scene.

                If you think trial and error is dangerous, try routine. That's even more so!

                  Did anyone tried this non-planar-Slic3r edition? I can't get something out of it, just messy G-Code...

                    @dc42... Do you think this can be implemented in Duet?

                    These movement, requires especial slicer and firmware?

                      It only needs special slicer. No changes in firmware needed

                        And that's what is exciting about it, as vs. prior efforts: It is available in a "mainstream" slicer.

                            Before everyone gets the underwear too messed up with excitement...

                            There is a possible issue of this already having being patented by another company which might stop it being used freely............

                                Cant remember, i will try to find the article again, i read it last night on one of the 3d printing blogs.

                                  and how different is this than a hexapod with 5 axis?

                                  sounds like someone is trying to patent the ESC key again

                                      @fma I had the same idea, and a question: how about building a DIY 3D printer with patented technology and then printing and selling 3D printed parts in a shop. Is this allowed?
