thanks Robb for installing fresh linux onto the 3D printer computer!
lots of people helped to get our giant snarl of white filament onto a nice
spool, which is situated over the printer, and it extrudes cleanly now.
I also checked that the bed is level, and it is. So i'm guessing it would
print OK. But I ran out of steam setting up slic3r.
so if anyone wants to work on that, go ahead. The hardware should be ready to
go.
