Arthur, This isn't my field, but I thought I'd seen something that at least fills part of this chain. The OpenBuilds-CAM and OpenBuilds-CONTROL software are AGPL https://github.com/OpenBuilds/OpenBuilds-CAM https://github.com/OpenBuilds/OpenBuilds-CONTROL Are these not part of the toolchain you're talking about here? The CAM software description says it takes SVG, DXF or Bitmap and produces GCODE for sending to CONTROL, which controls some machines. This does not seem to meet all of the toolchain you need, but it seems to fill at least part of it. -- Dr Andrew A Adams a...@meiji.ac.jp Deputy Director of the Centre for Business Information Ethics Meiji University, Tokyo, Japan http://www.a-cubed.info/ ___ libreplanet-discuss mailing list libreplanet-discuss@libreplanet.org https://lists.libreplanet.org/mailman/listinfo/libreplanet-discuss

I find Purism and their hardware some of best attempts to come to free software with free hardware in the world. So their project is just to be supported. They are smaller company, unlike IBM or other hardware companies, and their products will cost rather more than less. That is quite understandable. Try to make computer yourself and you will understand. > but they are not transparent My impression is quite contrary, they are so much transparent. > and are likely abusing their trust by constantly hiring new people > to claim that the development cost increased to infinity which is > terrible for user freedom. That is generalization, I cannot say I condone that neither I agree to that. I do not see problem with user freedom in Purism. Can you be more specific? Then also if you wish to tell something to Purism, why don't you tell it specific to them?

ART -- Arthur Torrey - --- As I understand it, when the source code to doom was released, the original levels stayed as non-free with a paid option to get them. Perhaps there could be a way to work with the hardware makers and free cad developers to create a similar set up where for a reasonable cost you can obtain the required drivers, firmware etc. FreeCAD would remain free as in freedom, if you wanted to use it with specific hardware you could do so. Just a thought, Ideally they would make their software available for free software available for BSD, Linux etc. If MacOS is based on BSD this can't be that difficult to port over surely. So this is a sort of meet in the middle approach that may work, as long as we, as a community respect the copyright, and pay for these components that should keep the copyright holders happy. The topic of funding projects came up at the meeting on Thursday 20th. So this idea is partly influenced by that and what happened with games such as Doom.
