Hi, Frank! I built it, and got it working a bit (uncalibrated, and quite sloppy), then had to take a break because I was buying and fixing up an old house. I tried to pick up where I left off, but after updating to the latest firmware and software, there is some sort of communications issue that I need to sort out. The main issue is I've lost mmy Reprap momentum and have since started other prby Andromodon - Minnesota Twin Cities RepRap User Group

I am running a 64 bit version of Ubuntu Jaunty. How did you set up your software? Are you using the 32 bit binary package on sourceforge, and just have "update-alternatives" set to point to your 32 bit java? When I do that, it complains that the .so files in the 32 bit reprap host package are 32 bit and not 64 bit. If you retrieved special 64 bit libraries, could you possibly send me a tar.gzby Andromodon - RepRap Host
Has anyone running 64 bit Linux actually gotten the Reprap host software to work? I have tried for too many hours, attempting everything from getting the 64 bit .so library files (results in a segfault in rxtx*.so) to attempting to install and use a 32 bit version of java with the ix86 reprap binary package. That dies with an "architecture word with mismatch" error (doesn't like the i386 librarby Andromodon - RepRap Host

Hi. Has anyone noticed that the two timing belt parts listed on aren't the same and won't work with the same pullies? The one from McMaster has a pitch of 2.03mm while the one from RS has a 2.5mm pitch. That's no good. Lastly, the third link is broken. How can this be fixed? ~AndyDby Andromodon - General
Hi. I am looking for a replacement 4 ft section of timing belt identical to the ones supplied by Ian from BitsFromBytes with his original mould-cast reprap parts kit. It has a 2.5mm pitch, 6mm width, .7mm tooth height, and 1.3mm thickness. As far as I know, it is the one at . Does anyone have some extra of this type of timing belt laying around?

Hello Ivraine! I am not able to (yet), but feel I could be really close. I have a full machine built, but it has not yet been calibrated or used yet. I've been renovating my house recently and that has taken priority for me. Maybe I'll dust it off and see how much progress I can make on it sometime soon? BTW, what sort of price range are we talking? Would you be willing to spend the same amby Andromodon - Minnesota Twin Cities RepRap User Group
Hey Demented, My original posting about HDPE absorbing water was in error. I was vaguely reading something about some filament absorbing water and thought it was HDPE. I shouldn't have posted that without knowing for sure. Sorry about that. ~Andyby Andromodon - General
Wow. There are clearly a lot of strong feelings on both sides of this issue. It reminds me of the subject of patriotism in the US. Sometimes, when a American citizen doesn't like the way things are being handled (for example with the Iraq war), and conveys this to members of the opposing party, they are accused of being unpatriotic.

This is a short story, set in the not-so-distant future, about the capability of a self replicating 3d printer to change the world. ( I am not advocating the printing of any patented objects. We can revolutionize and democratize the design and distribution of objects while working within the system. ) I hope you enjoy the story. ~Andy The following is copied from : -----------------------by Andromodon - General

Wow... It seems like someone else, just a little while ago, had the same problem as I did. Changing nullcartesian to cartesian in my preferences fixed the problem. What is nullcartesian for, anyway, and why is it the default? Also, if anyone has any insight into the errors I get, I would greatly appreciate hearing it. ~Andyby Andromodon - RepRap Host
Hello. I am working on the "Software Tweaking" page of the Darwin build instructions . Specifically, I am in the "Measure the deposited filament section" area of the page, which instructs me to, for the first time with this machine, print a .stl file, widebar.stl.

Keep the ideas coming! We should also make sure that the joint is easy to disassemble. It's nice to think that we'll put the machine together once, but unfortunately people make mistakes and sometimes parts need to be taken apart to get at other parts.by Andromodon - Mechanics

I would just like to add my two cents. There has been a lot of talk about putting heatsinks on the heater barrel in this and in other threads. Won't such designs require more power and heat the room significantly? Trying to heat one end of a metal pipe (even if it's stainless steel) and cool the other seems like a recipe for a high summer-cooling bill. If we can find another insulator (like Pby Andromodon - Mechanics
The current RepRap design, as fantastic as it is, does not seem to use the space it occupies as efficiently as it could. The build platform is 40cm x 40cm, and only about 25cm x 22 cm of it can be printed on (34%). Furthermore, while it looks at first glance like the bed should be able to go up and down a good 30cm or so, the Z pullies and printing head restrict the usable height to about halfby Andromodon - Mechanics
I was thinking about the original posting, and the need for some sort of coupler to join the two half-diagonal pieces came to mind. Check out the following thread for discussion on a modular connection design that could be used throughout the repRap design:by Andromodon - Mechanics
I would like to start a discussion about and a movement toward a single fastener design that could inch us closer to a fully repRapable design. The vision, as I see it, is a single, versatile, and modular coupling mechanism that could be copied and pasted throughout the design. Much of the time it takes to build a RepRap is spent twisting bolts with an allen wrench. As we progress to a designby Andromodon - Mechanics
...Sorry to jump in when everyone is talking about coord and cable, but I have a question. Why, again, do we only care about pulling forces here? As two opposite faces of a square move to make a parallelogram, one diagonal expands (pulling force) and one contracts (compression). So, it seems that if we are going to talk about pulling forces, we could equally (and symmetrically) talk about compby Andromodon - Mechanics
