Re: Arcol Hot End and Licenses - 12 years ago
Let me try to phrase this in a different way that may make it easier for some people to understand. The various Creative commons licenses do not and cannot place any restrictions on your rights other than those in the existing copyright law. Instead the CC licenses grant you limited exemptions to the copyright that allow you to make copies of the copyrighted work. The exact exemptions vary depenby kludgineer - General

What part of "No commercial reproduction" is so vague? On the other hand, if the MP3 were released with a CC-BY-ND license, then yes, you could release a for profit copy of it.

Re: Arcol Hot End and Licenses - 12 years ago
Sebastien: I don't think Arcol COULD define what you use the hot end for, at least with a CC license. The enforcability of the CC is based on copyright law, it is not an EULA. From my understanding if the law, you cannot use copyright to place any conditions on the USE of a device or piece of software. You can make an additional license that restricts it's use, but that is not related to CC, GPLby kludgineer - General
Re: Arcol Hot End and Licenses - 12 years ago
I disagree with the ND part of the license (though I believe that Sebastien is completely wrong on his interpretation of the NC portion), but the issues with the license are separate from whether you can safely order from him. Arcol is active in the RepRap IRC channel, and as far as I am concerned a valued member of the RepRap community. I use Makergear hot ends myself, but would not worry aboutby kludgineer - General

Re: RepRap sucks -- it's the worst of all 3D printers - 12 years ago
Casainho: You have some valid points here, but by framing the whole issue as an attack on the RepRap community, you have lost any credibility to deliver those points. In the Dev list posting, you lost all credibility when you made statements that were flat-out wrong (that the Reprap lacks support material, for example). Think of the Reprap project as analogous to the beginnings of the automotiveby kludgineer - General
