Moving into rotational axis, mapping 2.5D relief to oak cylinder from recycled lamp. Not true 3D because I’m using the X axis as if it was flat and limited to the diameter of 119mm. It’s a trivial way to get 3D objects without full 3d models and it has a long history in art. Reliefs are a major part of the story of the development of linear perspective and mapping textures to surfaces is not just for gaming any more.
Looks promising…
Even with compensation for changing path distances as the radius gets smaller and 360°=0° it would still be 3 axis because you are moving only X, A and Z and Y is not used.
A is plugged into the X axis not Y. Compensation is not trivial if I was machining parts, but not really needed for mapping 2.5d to a curved surface (119mm diameter and 2-3mm z cuts). I did a 9mm depth cut to see what the changing diameter does and it is not as much of a problem as the added curvature of the relief which really distorts things a lot, and a cool effect I think I can use to get some interesting cuts in non standard ways, the artist’s eye for what a tool can do. 
I am learning a lot about how many ways there are to do the same thing and how many ways to rethink how things have been done.
DeskProto works very well as the CAM to do these sorts of artistic things. You should give it a try.
Thanks, I’ll add it to my long list of tools I have been learning to use. Too many ways to do this stuff and none of the good ones are cheap enough for STEAM programs in schools where teachers are not even paid a living wage.
Unfortunately is seems most of the Open Source community is not interested in doing art so I have to use some commercial tools and that means more costs for artists who are the ones with the least money in this tech toy obsessed culture. Sad but the maker world is mostly guys who just like to play with toys or people who want to use the tool to make money.
On the other side, artists are overwhelmed by having to learn complex software and awkward workflows. Getting artists to collaborate becomes a struggle to help them learn these tools. Understanding the limitations of taking what they draw on paper and milling it is not easy when they lack the engineering background to define things clearly.
I have no clean what STEAM and STEM are. Is it some US-american thing?
I did not even mention STEM so…
So what is it? I can infer A to mean arts and I guess that you are teaching adults. I guess that in this case you’d be a teaching professor or assistant of scultping. So the students would get offered things like basic workshop safety, materials and basic usage of modern tools in addition to human and animal anatomy, art history, some economics and basic business. I can imagine this to be the more in-depth and more wide ranging education compared to the more hands-on way of being an aprentice to a master in the non-university branch of education. …just guessing.
I’ve taught k-12 and at university and have always lived in both the art and techie worlds.
No need to guess any more with the Internet. STEM and STEAM are easy to look up and your “guess” seems to indication you did that.
I looked it up but I didn’t understand it. Getting my German diploma in computer science (minor subject math) was vastly different from anything I was reading. Not only because it was free and I got an interest free loan for about a decade to cover living expenses. It sounds like studying a dozen subject but none of them in the level of detail I expect from a university education ending in a master degree or diploma.
Well, not sure what you are reading but STEAM is just about integrating arts and sciences because the system is pushing STEM and dropping arts programs.
Look up the Bridges - Art and Mathmatics group founded by George Hart if you are interested in what some folks with degrees are doing in both k-12 and university.
BTW, I have no credentials if that makes a big difference to you.
