This is probably a good time to raise this Zach. Does the EFF have a model for doing this, does anyone know?

That's certainly worth bearing in mind, but now that Ed (following Vik) has got making them oneself fully sorted (complete with for-free internal thread that goes straight on the Darwin drive rods), let's stick with that for now.

Actually, that's brilliant! (Not the lift-off, but up to that.) In that it's obviously going to work.

Fortunately I have little hair... I am about to do a frightening thing - freeze some parts of the design (except for correcting actual mistakes), and create a timetable of what's to be done up to the release of RepRap 1.0 "Darwin". I'll do it at Zach's parts database should link in very nicely with that. I think that it is complementary to objects.reprap.org (as Zach indicates below). Oby Adrian Bowyer - Developers

If you're building an extruder you put R3 in; if you're building a stepper controller you replace the right-hand end of it with a via.

Dark suspicion confirmed, but it was a simple, if subtle, hardware bug: if you wire the Universal for stepper control it doesn't need the thermistor resistor R3. But one end of R3 also forms a via for the sync pulses... Given the similarity of the problem to Vik's return-to-zero-for-cooling bug, I'll start looking in the sync code for that too.by Adrian Bowyer - Developers
That old bug that Vik discovered in the stepper routines that caused the Y axis to move somewhere but not the X (it only showed up in the "return to origin while cooling" code) has now spread to disrupt everything :-( However, this is not as bad news as it sounds, as at least now I'll have to fix it properly rather than doing a workround.

Good find! The one third from the left at the bottom looks good, especially if they do a threaded version. These are for wire drawing, I presume, so they'll be very hard (which we don't need, but it doesn't matter).
