... The only negative symptom left was that the printer froze mid-print when I was printing from the SD card. I believe this is due to a conflict with both the thermocouple module and the SD card using the SPI. It prints reliably when I print from the computer i.e. without using the SD card.

Peux tu donner un lien pour ton extruder ?

Salut starzleo,
L'extrudeur que tu peux voir dans ma vidéo est une toute petite modif (pas encore publiée) de celui-ci:
qui a déjà été remixé 23 fois! Donc tu as le choix de la version qui s'adaptera le mieux à ce que tu veux faire/construire.

Un grand merci pour ce retour d'experience, comme tu as les competences pour construire la pièce CAO je te suggère
une autre version de ta pièce pour le blocage de la courroie en faisant comme cela
je trouve que c'est vraiment pratique pas besoins ainsi de collier et le blocage est très très bon puisque c'est dent de courroie

I have to take back a couple of negative comments I posted earlier about Michael Weinberg's article "What's the deal with copyright and 3D printing?"
1. I wrote earlier that the article was missing precise references to the legal cases mentioned by MW. This is incorrect, the article has abundant footnotes that provide proper references to all the cases mentioned. Somehow the PDF viewer I used th

Hey, you forgot Misconception 6, about the fact that a CAD file (source or not) does not necessarily contain what is legally needed to define a design. With this I mean that the architets who register their designs do not just submit a CAD file (look here as a random example of what is required, which is more than I usuall

According to GPL V3 Q&A, the output of GPL V3 software can only be GPL V3 licensed if that output contains a significant portion of the licensed code. STL files contain none of the original OpenScad source at the moment. Is there a way of adding it as a comment into the STL file? I ask this because tools exist that can modify STL files which then circumvents

Hi Craig,
Thanks for joining this thread.
Answering your question, you can check a link I posted earlier here in this thread, to a page written by Eben Moglen:
Enforcing the GNU GPL by Eben Moglen. Note the text dates back to 2001 (14 years ago).
So apparently the GPL has legal validity and is enforceable in court, at least in the US and at least in some cases.

OK Matt, while I wait for you to clarify that last point, let me summarize your position and where we disagree:

Although I encourage you to learn OpenSCAD (learning the basics takes just a few hours and there are tutorials on YouTube), personally I would not bother with trying to reimplement the canted aspect of this particular design, if you really need the extra clearance that this design claims to offer there are many different and imo better ready-to-print solutions on Thingiverse.

I had further discussions with the person who advertised the "Canted Wade's Extruder" for sale. He says that his OpenScad files do not contain any of Wade's or Greg's original code. He described 're-engineering' from the ground up.
The problem with free software is that anybody not releasing sources may claim to have re-engineered it from the ground up, even if

Salut AndrewBCN,
Désolé je ne viens pas t'aider parce que je crois que nos avis diffèrent.
Avec la licence GPL, tu peux "protéger" du code, mais aussi éventuellement d'autres œuvres telles que des plans et fichiers 3D. Par contre cela ne s'applique pas à l'idée: Si quelqu'un aime ton design et souhaite le refaire à partir de rien pour l'améliorer, il ne sera pas tenu de placer so

I confess I am finding myself in a strange position in this thread when it comes to the GPL, because many people are expressing their opinions about it without having actually read the text of the GPL.
It is much like arguing over the US Constitution with people who have not read it (and its amendments).
So: text of the GNU General Public License V3 (GPL for short).

Hello,
I agree with you MattMose when you say that EmotionTech have the righ to redraw their own models from scratch and diffuse them. Doing so, I think they are not in violation with the original Prusa's files licence.
But they release their own STL under the GPL licence, then they should distribute the source files. If they do not want to distribute the source, they should use an

Is what they did in violation of the GPL?
It depends. If they created their models by modifying Prusa's OpenSCAD files, and they happen to be sitting on these modified OpenSCAD files and they refuse to release them, then YES they are in violation of the GPL. However! If they re-created their parts in some other CAD format, or if they wrote their own new OpenSCAD files from the
