Hackerspace Brisbane gets its first Mendel!
lots more pics here:
https://sites.google.com/site/davidbuzz/hsbne-mendel-reprap
After a number of days of furious tweaking it prints!
problems included:
* pulling the extruder apart at least 10 times
* a leak
* a hot-zone conection failure
* a missing bearing
* mis-aligned cogs
* PTFE failure ( saved by a hoseclamp)
* two thermistor problems
* inverted end-stops to normal
* stepper driver pinout weirdness and ground loop issues - 5 hours here!
* X & Y axis needing reduced stepper power
* E & Z needing increased stepper power
* cog on X stepper came off
* X stepper mounted 4mm too low
* X belt too loose, then too tight, then too loose!
* a couple of random nuts falling off from someplace
* smooth-rails on X were insufficiently tightened, see belt issue.

The artifactory (Hackerspace Perth) got ours going about a week ago. Good to see someone else in Australia is going strong. For an extruder we found that the biggest problem was getting the Y-axis to stop wobbling, once we did that it was almost smooth sailing.
That said, we used a plintruder for our extruder, which was very easy to get going.

We've got 4 Australia RUGs going in the forums for Brisbane, Melbourne, Perth, and Sydney. You guys may want to check in there.
