QuoteMattMoses For awhile there was a site called physibleexchange.com, but now it looks like it has turned into an unrelated blog. Anyone know what happened to that one? Apparently physibleexchange turned into Thing-a-ma-Print. I guess those guys don't read this forum... Here's an updated impartial alphabetical list! 1. 3dhacker 2. bld3r 3. Cubehero 4. FAB Fabbers 5.

Hi Kalle, I like it! Compliant linkages are discussed occasionally around here. VDX pointed us to some really cool work over in this thread - basically a 3-axis cartesian manipulator that folds up from a sheet of material. I wrote up a simple (1-axis) proof-of-principle experiment here. There are a lot of interesting devices in the See Also section of that writeup. See in particular the 2-axisby MattMoses - General
Check out: Low-melting point alloys "Then I looked at the silicone tubes I was using to carry the cooling water. Dang me if they weren't 3mm internal diameter. I put one on a funnel with a clothes-peg at the other end, heated them all in a beaker of boiling water, took them out and quickly hung them up, then poured in the Wood's metal: After it had cooled I just sliced away the silicone tube witby MattMoses - General
Well... if you don't like the wiki, here is a list of no less than ten different alternatives. Although admittedly some of them are not exactly up and running yet... What exactly do you mean by "truly open source"? The code running the site should be open source? The available licenses for uploaded content should be open source? The philosophy of the people running the site should align withby MattMoses - General
Quoteohioplastics Perhaps an STL Wiki. I don't know why reprap.org hasn't started it's own repository. The RepRap Wiki has always been able to handle STL files. And there is a whole forum just to talk about projects you post on the wiki. Check out this nice example: Sarrus linear axis with RC Servo.by MattMoses - General
The RAMPS 1.4 wiki page should have all the schematics you need. The actual program the mega2560 is running is called "firmware". There are many kinds. Here's a big list of firmwares. Many people use Marlin, you can get the Marlin source here. I don't think there is a "standard" for color in 3D models. Some commercial printers use VRML for color, see here for example. The AMF standard supportsby MattMoses - Developers
> Not a good idea, disconnecting and connecting stepper motors to a driver under power will damage the driver. For something low power like a Pololu driver it probably doesn't matter that much. I have hot-swapped stepper motors by simple "plugging and unplugging" and the Pololu drivers don't seem to care... But you're right that it is not good practice. If you're worried about it, you canby MattMoses - Developers
richrap did this with three extruders - see details here. He ran the same stepper channel to three different stepper drivers and controlled their enable lines individually. Simba is working on a 10 motor design, but it may not be ready yet... If you're ok with really low-tech, you could get four 1-pole 8-position rotary switches (one switch for each output wire of the stepper driver). That wayby MattMoses - Developers
Maybe we can say homeprototypes is in hibernation. "Abandoned" sounds so harsh... Quoterichrap Has anyone any views on the Githubiverse Template... Sure, I think it's great! I mention it frequently in threads about TV alternatives (see here, here, here, etc). I'd like to try using it. But (like a lot of people apparently) I don't really have much of a clue how to get started. The other day Iby MattMoses - Object repositories

A 3D printer controller is different from 3D printer controller firmware. Many of the common 3D printer controllers have pretty solid documentation on the wiki: RAMPS 1.4 Melzi Sanguinololu etc... Most of the RepRap firmwares use the Arduino platform, which makes modifying code easy, even for non-specialists. Making minor changes to the Marlin source code is a fairly common part of the calibratby MattMoses - General
If you haven't found it yet, the G-code wiki page might answer some of your questions. There are a lot of people on the RepRap IRC that would be happy to talk about this as well.by MattMoses - General
Marlin is controller firmware. This page on the wiki is a little out of date, but it shows a high level overview of the software toolchain: CAM Toolchains. The G-code is generated by a slicer, like slic3r for example. Once the G-code is generated, a printer communication program like Printrun sends it to the printer controller (which is running the firmware), usually via serial communication suchby MattMoses - General
QuoteSanjayM I am deadly serious when I say I want to print a working J-Head type hotend out in full, using dual extrusion of FEP and PEEK, but obviously with a brass nozzle. Why obviously a brass nozzle? You could print a mandrel out of carbomorph and electroform the metal part of the hot end around it.by MattMoses - General
It is great to see all your cool designs, Nicholas. Thank you for sharing the files. If you haven't seen it already, you might like the Rhombot. It is kinda similar to the Tripteron.by MattMoses - Delta Machines
QuoteTraumflug What's wrong with the wiki? Excellent for documentation, pages can be "watched" to never miss a change and you can upload all sort of files, including STLs. I agree! Maybe people think editing a wiki page is too finicky, or they want more of the social aspect. But between the wiki and the Look what I made! forum, all the pieces are there... I suggested some ways to streamline wikiby MattMoses - General
Part 2 Say you want to create a github repository for one of your own projects. Maybe it's one of your projects on Thingiverse. Here is the one I used for this example. Maybe you forgot where your original files are, so you just download everything from Thingiverse in a zip file . Make a directory, and put your files in it. On my windows machine, I put my files in the directory "Kites_and_Dartby MattMoses - General
Well, if you just want to use straight up GitHub it is not too hard to get started. The best thing to do first may be to clone as existing project. Step 1. If you haven't already, go get git over here Step 2. After installing git, open git bash and follow the simple setup instructions here Step 3. Now just for fun, clone an existing project. How about a Prusa Mendel? At the Git Bash "commandby MattMoses - General

jamesdanielv, I took pains to be polite in my post and pointed out explicitly that it was not intended to be a personal attack. With all the other hostile rhetoric being bandied about here, why do I get the pleasure of the "just don't attack each other" directive?by MattMoses - General
DarkAlchemist, it is strange to see your strong support for open source when you yourself have said you would never share the source files for your own work. In this post you said QuoteDarkAlchemist I just know you would never get the original file from me if I had worked on something for thousands of hours. and in this one you said QuoteDarkAlchemist Look buddy I am not here to design sometby MattMoses - General
akhlut, you cite one of Zach's blog posts as supporting your argument. Now, just to be clear here, I do not think Bre Pettis deserves the crap you guys dump on him. Not at all. But, as long you insist on dumping, you should reserve equal measures for Zach. The Zach/RepRap relationship isn't all peaches and cream either. As Jon Stewart says, one should be consistent with their outrage. Imagineby MattMoses - General
Is it already time for another bash-Makerbot thread? It seems like we just had one... For those who are new around here, every few months we get whipped up into a frenzy about how horrible Makerbot is. It is important for you to know that most of this hysteria is fomented by only a very few individuals. We all seem to put a lot of stock into the words of Adrian Bowyer.

From the link: QuoteDglass3D You will notice that we have removed the image of the extruder head guts, we are saving the good stuff for our Kickstarter launch!
