Englewood, What exact version of Sun Java are you running (Start -> Run, cmd, Enter, type in java -version and press Enter. Tell us what it says.)? Also, exactly where in your system did you put the RXTXcomm.jar file and the associated two .dll files? I'm wondering if you have somehow got Java to see the RXTXcomm.jar file OK, but not its native code .dll files, rxtxSerial.dll and rxtby jmarsden - RepRap Host
Dan, Thanks for the writeup. I posted a similar but much more wordy description (and possibly mildly confused, given how late it was at the time!) of how I got a full host software development env. onto Windows at a couple of days ago after my first attempt at doing this on Windows. The whole "where do I put the libraries" deal is a mess. I'm hoping to create an installer using NSIS that droby jmarsden - RepRap Host

Zach, Let's see. I've been replying to a bug report on the setup script, enhancing the setup script as a result of that feedback and re-publishing it, and playing with some initial ideas about repackaging Java3D and RXTX libs for simpler installs, all while engaging in this dialogue. Oh, and trying to point Eric towards a solution to a current issue with Lamarck once or twice. And exchangingby jmarsden - Developers
That does sound odd. Maybe try: (a) diff the two .hex files you are using to program the X and Y PICs from, and make sure they only differ in the one address byte (02 for X, 03 for Y)? (b) read the program out of the PIC when it is flashed as first X and then Y, saving the results into some new .hex files, and verify that these two read-out files also only differ in that one byte (one bit,by jmarsden - RepRap Host

So yours is currently a closed development model, with code (whether 4K or 10K or 25K lines of actual code lines after you exclude the comments and blank lines really doesn't affect my basic argument much -- how many 14yo non-programmers will feel comfortable reading and enhancing 4K lines of code?) released only to a trusted few.

OK, here is a slightly enhanced version of the script. It tests for the presence of the tools it uses, such as unzip, wget, svn, java and javac, and displays an error if they are not found. If you run it under Ubuntu, it should also include in that error message a suggestion on how to use apt-get to obtain the missing piece of software concerned. Jonathanby jmarsden - RepRap Host

If you could let me (and the Internet public) "see" your plans for making a 25K line software codebase easily accessible to geographically dispersed 14yo non-programmers for ongoing development, and "see" the latest status report on how implementation of that plan is going, that would help me "see" much better.

Forrest, I don't understand your response... all the examples I gave were (very intentionally) of applications, not operating systems. All of my example applications will run under other operating systems than Linux. Even including proprietary non-replicable OSes, such as Windows. Every single example application I listed was chosen in part because I know for sure it runs on Windows as well aby jmarsden - Developers
I provided multiple reasons why the parallels may not apply, or may be significantly less applicable, in my post, I think. As for examples used in evidence for my own current position -- OK, let's look at this.

This remains an unproven hypothesis (in the context of FOSS software in an Internet-connected community) unless you supply specific examples.

Englewood, If you are not a Java programmer, *please* don't try to set up a software development environment (Eclipse, Subclipse, etc.). It's just extra complexity to confuse you, unless you really are going to further develop the software yourself. Just use the reprap-host-0.8.zip package plus the libraries. There is only one rxtx zip file that is needed. I thought I posted a specific linkby jmarsden - RepRap Host
Thanks. So, to get back to the practical question at hand: is C1 rated at 16V and 125C going to last any longer than one rated at 50V and 85C on the PowerComms board? Is it possible to determine that with any certainty? Are C2-C5 (50V 85C) appropriately rated too, and if not, what should their rating be for optimal cost/size/lifetime tradeoff?

You should be aware that Reprap Java host software development is... probably somewhat less well tested than host software development under Linux. It should be doable, though.
