After many months of being vaguely interested in 3D printing, I decided in July 2014 to "jump in the water" and in August 2014 I began buying the parts for a P3Steel (a Prusa i3 variant built out of laser-cut steel parts). As of October 2014 my P3Steel Raffaello is already operational and I have printed my first "reasonable quality" parts. I am also building a second P3Steel Michelangelo.
All along this great wiki has been an essential source of information, so to give back to the community I have decided to contribute a few pages of my own here:
- Some contributions related to using ATX PSUs for RepRap projects.
- Some contributions related to the P3Steel assembly process.
- A couple of pages where I try to determine the history of some designs, for example some of the Prusa i3 printed parts and Greg's Wade's Geared extruder.
My thanks to all the pioneers in this fascinating new technology, and to all the previous contributors in this excellent wiki!
Those Incredible Editors
Regarding this spam on the front page: it's kind of fascinating how ignorant some advertisers are. Says a lot about how dumb they think we are. And thanks for saving the front page.
What I wanted to say: near the "undo" link there's also a "rollback" link on the last edit. It's purpose is exactly the situation you saw: it undoes all edits of a particular user. --Traumflug (talk) 07:10, 15 February 2015 (PST)
- Thank you Markus! I'll use it next time, hoping that won't be the case too soon!
Prusa I3 Rework losing its open-source status
First let me apologize if this isn't a good place to contact you. I was just trying to get in touch with you about the discussion over the Prusa I3 Rework because you had the main post on the discussion about it not being open source anymore. If there is a better place to discuss this let me know!
Anyways, I just finished a 26 video tutorial over how to build one of these. This printer was my overall introduction into 3D printing. I built one to learn how to do it, and then I built a second one and made a tutorial based around it, to help any other newbies like myself. Only a week or two after posting the videos on youtube, my boss noticed the error on the RepRap page for it. So my question for you is, is there anything I can do to publish the correct sources? and add the necessary files or documents so it can regain its status? I don't fully understand how all of this works, but I am willing to try and correct the errors. I am hosting all the .STL files for this printer in a repository on our GitHub page as of yesterday.
Any of your help or advice would be much appreciated!
- Hi,
- First, let me say that by all means I think the i3 Rework is a good printer, one of the most popular variants of the Prusa i3 and that it has many interesting improvements over the classic Prusa i3.
- Now, let us begin with the Prusa i3 and the Open Source license under which it was published, the GPLV3. This license specifies that any modifications done to any of the parts should have its sources published under the same license. So it does not matter if you modified any of the parts of the Prusa i3 using OpenSCAD or SolidWorks, you have to publish the source files if you want to comply with the GPLV3. And provide proper attribution: the original author/designer of the Prusa i3 is Josef Prusa, and any derivative design should provide proper attribution to him, as well as whomever designed the modifications.
- Finally, there is another sticking point with the Prusa i3 Rework and that is the extruder. It is a variant of the Greg's Wade's Geared Extruder (GPLV3 license) which I have analyzed here: http://reprap.org/wiki/Genealogy_/_Archeology_of_the_Greg_Wade_Geared_Extruder
- But it is actually an almost exact copy of the design by ch1t0 (Ramon Garcia) who himself failed to comply with the GPLV3. If you want the i3 Rework to become fully Open Source compliant, I suggest you contact ch1t0 and ask him to comply with the GPLV3, or reverse-engineer his derivative design and make it GPLV3 compliant, or contract somebody to do it for you (for example, me) in a professional manner, and complying with the Open Source license terms.
