Re: [OpenSCAD] Project Announcement Makertron
That sounds great. I have a beaglebone I could try that on , but am not so familiar with it, and no replicape. I use Raspberry Pi/OctoPi all the time, and it’s a bigger user base… can I tempt you? ;)

Alex,
Yes! I've had this on a beagle bone with MachineKit ( but -not- in the docker containers in the current deployment). I was attempting to do just that. Send SCAD straight to the Beagle Bone which has a copy of Machinekit and the Replicape board plugged in to it.

Final idea, and I think it could be amazing if you did it, and really help get traction:
Have you considered making this a plugin for OctoPrint? (Defninitely to include OctoPi)?
This would instantly enable a lot of people to host it on a Raspberry Pi 3 server.
I would love to be able to edit SCAD and just send that to my printer server – so efficient!
There is already a slicing engine, CURA, available as a plugin – maximum score if you could integrate with that too!

This is such a great forum. This is some wonderful feedback I am getting.
One of the things about the Makertron is that both the client and server components are docker ready.
So if you are in a locked down environment you can pull both the server and client and build both the client and server image and deploy them locally in to a docker.
Instructions are in the github documentation to do this but are by no means complete!

Oh also to get the default model to load you need to click on the

As noted initially: "When pressing the Generate button, nothing happens."
Requiring port 3000 is a no-no on this network. The page loads with http://makertron.io but not with http://makertron.io:3000. When loading with http://makertron.io, clicking Generate provides no response at all (multiple tries).
The port issue appears to prohibit any further trials on this network.

Thanks for that. I can see that I have missed out a few different combinations of values for input in to the transpiler.
I’m interested in the transpiling/compiling part.
Since Makertron has to understand the entire OpenSCAD syntax as well as semantics, it sounds like a full parser is eventually necessary.
There are a few projects in the pipeline for establishing a stand-alone OpenSCAD parser library:
- C++: https://github.com/openscad/openscad/pull/1743
- Javascript: https://github.com/hhornbacher/node-scad-parser
- Javascript: https://bitbucket.org/openscad/openscad-js
The latter two are early experiments and only really supports parsing into an AST, but there is code scattered around somewhere that attempts taking it a step further.
It would be nice to have an official library which is kept in sync with the C++ implementation, but it needs someone to help care for it.

Hi Alex,
I think Minkowski is a great idea so I have started doing an
implementation. Minkowski is an example of something quite a bit more
complex in the OpenSCAD that is welded to the CGAL. Alongside that I will
also be doing a more direct port of the primitives so that the '$' options
work as expected. Aside from fillets what else can you do with the
Minkowiski?

If you’re going for OpenSCAD compatibility – and it’s online –
how about flagging back to you every time a function is hit that your app

other kinds of error, it will give you and the people trying the app
instant visibility of where the biggest wins are, and you could also

Minkowski looks pretty easy to implement compared to things like union.
IIRC for a convex shape it is just a hull of the set of the set of points
summed with the other set. For a concave shape it can be decomposed to
convex shapes and then it is a union of resulting hulls().

Hi Guys,
I pushed out a first pass at Minkowski today. I've incorporated the CGAL
functionality in to the brep shared server. Still just regularly adding
things and quietly doozering away. I've also put up a feature matrix which
I am slowly filling in.
