This has happened before and usually there is an easy fix for it. Feel free to send me a PM with the text you are trying to post (I think it will make it through as a PM) and we can figure out what it is triggering on. As we've pointed out before, we can't publish a list of banned terms because that would make it very easy for a spammer to circumvent.by MattMoses - General

OK, I changed enough things for one evening. Time to quit before I break something. Here is a summary: Moved Prism topics to "Mendel and Prusa Mendel". After the old empty Prism forum was deleted, it broke redirects to the Prism topics. By sheer dumb luck I had decided to write down all of the Prism topics and links before moving them, so it was easy to create a list of links to the new locationby MattMoses - Administration, Announcements, Policy
This is for archival purposes. As part of the "Machines Variations" reorganization discussed in this thread, all topics in the Prism forum were moved into the "Mendel and Prusa Mendel" forum. After the empty Prism forum was deleted, old links to the Prism topics apparently no longer redirect to the topics in their new locations. Here are updated links to all of the topics that were in the Prisby MattMoses - Administration, Announcements, Policy

QuoteAndrewBCN I really wanted a separate folder or subforum named "Prusa i3 and variants" OK, OK. We can make an extra forum for Prusa i3. How's this?

It looks like we all want something different. But I have not yet given up hope of making everyone happy. How about this one? We split "Machines Variations" into two top-level folders, "Machines Organized by Name" and "Machines Organized by Kinematics". And we also create a new top-level folder called "Legacy Forums" that goes at the bottom of the whole page. It would look kind of like the pictby MattMoses - Administration, Announcements, Policy
You could try Polycaprolactone (PCL). It melts in hot water. It may be hard to find in filament form, but it is available many places as pellets, and not too hard to make your own filament. The process is described on the wiki here: Polycaprolactone.by MattMoses - Developers
This is part 2 of a 2-part reply. OK, so how about this: Within the "Machines Variations" folder, create three new folders: Legacy Machines - old designs no longer in widespread use New and Experimental Machines - CoreXY, Delta, Polar, SCARA, and more Specific Machines - Mendel90, Prusa i3, Ormerod, and more Next, move (and rename where applicable) all of the existing forums in the Machinesby MattMoses - Administration, Announcements, Policy
This is part 1 of a 2-part reply. I was getting confused on terminology, so I made these two little graphics to help keep the terminology consistent. there are folders, forums, and topics folders contain other folders folders also contain forums forums contain topics forums do not contain other forums forums do not contain foldersby MattMoses - Administration, Announcements, Policy
I was thinking about this a bit more. There are quite a lot of Prusa i3 posts in the "Mendel and Prusa Mendel" subforum, so maybe we do not need to create a new subforum. And ideally we want to reduce the number of subforums, not keep the same and certainly not increase. So how about this: 1. Rename "Darwin" to "Legacy Designs - older designs no longer in widespread use". 2. Move all topics ofby MattMoses - Administration, Announcements, Policy

This sounds (mostly) like a good idea to me. I have not done this kind of forum reorganization before, but I can give it a try if we find consensus regarding what goes where. In response to your specific suggestions here are my own opinions: QuoteAndrewBCN 1. Archive or merge into an "Older designs" subforum, both the Darwin and Prism subforums. Yes. No problem.

QuoteIanJohnson Low temp alloys like Rose's metal or solder aren't good for extrusion because metal is runny, and doesn't have an ooze stage where it can be melted and hold some shape. You can make a low temp alloy that does have an "ooze stage", as described here. You can also get decent results simply by putting off-the-shelf solder right into your printer, as described here.by MattMoses - General
Also, not to derail the discussion or anything, but if anyone wants to read a slightly amusing blog post from 2010 where Bre Pettis is bashing the heck out of an electronics developer because they did not post their layout files on the RepRap Wiki, you can click here.

There are different questions here. The main question is: 1. Did the designer upload sufficient files to create a copy of the design? In the case of Alligator Board, the answer (at the moment) is NO. The board layouts are missing. The other question (which we usually end up arguing about) is: 2. Is CC-NC-* license an open source license? Based on many many many previous discussions about thiby MattMoses - General
Yes, there is a big debate on what it means for a hardware design to be "open source". For example, the Open Source Hardware Association defines it like this: QuoteOpen Source Hardware Association Open source hardware is hardware whose design is made publicly available so that anyone can study, modify, distribute, make, and sell the design or hardware based on that design.
