Timetable to Darwin release

People (and I don't just mean us ourselves) are beginning to champ at
the bit and ask in earnest, "When can I have a RepRap, then?"

So I have roughed out a timetable at

[reprap.org]

I have taken the liberty of putting Xs under the names of one or two
other than Ed and me, but only where people have already said that
they'll do a job.

Can people edit this however they like: add Xs, add or change dates
etc., and add things to do. Just don't delete any Xs (unless I've
volunteered you by mistake...).

Most of us are reasonably familiar with AoI now. Ed's translation job
is going to eat into the other things that he does, so would people like
to have a go at taking some STL files and backwards engineering them to
an AoI construction? If you would, put your X in the row and Ed'll send
you an example Darwin STL file.

The release date obviously becomes the latest date in the second column
+ two weeks (say).

It all looks alarmingly do-able...

***It all looks alarmingly do-able...***

It sure does when you put it all down like that.

Looking at the list, I don't see anywhere that I could usefully help on the tasks that you've outlined. It's worth pointing out that Bart seems to be making a good faith effort to getting the Windows version of the Java software rolling here in the states. You might want to involve him on that task.

I was thinking that where I might be useful is in devoting a fraction of Tommelise's machine time to printing those Darwin connectors for second level users when I get the printing software/hardware ensemble running right. I plan on putting a spackling compound (polyfilla) extruder on the system for support material so that I should be able to do those parts. I thought perhaps people who wanted parts sets could, say, send me about twice as much filament as was required to do the job to cover for the machine time and electricity. That way no money changes hands.

Do you have any idea which plastic you're going to want to use to print the Darwin parts? I can already run HDPE really well with the modified Mk II that I'm using right now. I'm also pretty sure that I can run HPP as well. For really fine detail work, though, it looks like ABS is going to be the ticket. I've sketched out a beefier polymer pump for ABS the printing of which will be one of my first priorities on Tommelise. The ability to get effectively 0.5 mm extrusions of ABS out of a 0.5 mm orifice is very attractive.

I'm chewing on it right now. A thought occurs to me - we should see if any of
the forum-folk want to help.

Also, could you send me the dwg, and maybe a lower-polygon version of the stl
file? I'm using blender to measure all the parts of it.

how big are the files we're dealing with here? if they're under a few
megs, they should probably be in subversion. i'm not sure if
sourceforge has a limitation, but if so then we should set up our own
repository. i have a terabyte of storage sitting idle and the offer
still stands. food for thought.

For STL's which tend to be the biggest files: typically a few megs. Max 10
megs.

Do you mean an orthographic dwg? There aren't any of them yet - doing dwgs
of all the parts would take a while and become redundant when the AoI
models are complete. But perhaps I could send you the solid edge file? If
it's a must then of course I'll draw it out, Let me know - i'm stuck into
the assembly instructions at the moment which is turning out to be a bit of
a mammoth.

If you run that bracket through AoI, and optimise the mesh you get a 10x
reduction in the triangle count.
