I agree that it's very important to have a multilingual project, but I also agree that we don't have the time at the moment. Remember that everything is secondary to making a working replicating machine. Once we have done that, everything else will happen by - if necessary - others taking it and running with it.

Looks a pretty good list to me. Long term, I'd like to switch to an internal 3D solid representation that is pure CSG. It's implicitly robust, it is simply incapable of representing anything that isn't a true solid, you can slice it just by saying z = 7.3; you can offset it just by saying c = c - 0.35; and so on. But that does mean implementing the 3D version of Woo's algorithm to convertby Adrian Bowyer - Developers

Sounds fine to me. Now that we have reasonably reliably working hardware it's much easier to debug the code by trying it. Plus I (for one) am now approaching the idleness of the Summer Vacation, so I hope to make some impact on remaining code problems in the next month or two. Most such changes are pretty trivial to do, but have a big impact. For example today I changed the code that runs rby Adrian Bowyer - Developers
OK - so put AoI files up as I proposed, and have the STLs on Sourceforge updated as at present seems to be the consensus. For the Darwin design remember that we don't (yet) have the construction geometry, as the STLs were exported by SolidEdge. We only have the final shape. That's editable in AoI, but some edits will require a bit of reverse engineering...by Adrian Bowyer - Developers
***I propose that anyone putting files into the SourceForge "File Release System", should avoid using version numbers other than dates, 0.x, or 0.x.y (where x and y are base ten digits 0 through 9, in case that's not clear) unless the file(s) concerned truly are official tested releases and there is at minimum some sort of prior agreement that they are appropriate for public release (and relatedby Adrian Bowyer - Developers
We had a bit of a debate a while ago prompted by Simon's pointing out that svn wasn't ideally set up to deal with large binaries like STL files. Apologies to whoever thought of the idea that I'm about (absentmindedly) to echo back as my own: I'm thinking of removing STLs from the distribution altogether: the svn structure that we have set up (host, electronics, mechanics, and firmware) seems niby Adrian Bowyer - Developers
Jonathan - I want to make a change to the firmware. I wish to add another extruder (for support material); it'll start identical to the one that's there but with an address of 9. It will then diverge as I edit the code. But I don't want to tread on what you're doing, so if you could do the file copies - extruder1.c and extruder2.c (the .h file should stay the same) - and Makefile edit, then cheby Adrian Bowyer - Developers
I think we're conflating two distinct things here: 1. How to number files, and 2. What constitutes a release, and when do we have one. The only intersection between these otherwise distinct questions is when a numbering system implies to the world that we've made a release when we haven't. The problem is that a proper numbering system is both the best way for us to handle things internallyby Adrian Bowyer - Developers
I've just checked in another upgrade to the preferences system. It: Splits the preference menus over multiple columns if there are a lot. Improves the readability of some of the key names. Actually uses the preferences to set things (like colour) in the GUI. Best way to approach this upgrade if you want to preserve your own reprap.properties file is to print that/save it elsewhere, copyby Adrian Bowyer - Developers
I have further updated the preferences system. It's now more complete, but maybe slightly less friendly. Specifically: It constructs the edit menus entirely from the properties file, so any change to that automatically gets reflected with no programming required, and all the properties are editable in the menu. It deals with multiple extruders. What you need to do: Globally edit your preferby Adrian Bowyer - Developers
I've just committed changes to the Java reprap.preferences system so that extruders are now completely in charge of all the parameters that may need to change when an extruder changes. This means that people will have to update their reprap.preferences file (though not the reprap.preferences.dist file). The changes are just in some names: MovementSpeed => Extruder1XYSpeed ExtrusionSpeed =&gby Adrian Bowyer - Developers
