Greetings Andrew and Lonn,
Seems I'm in between in Calgary. I've started pulling parts together
for the Cartesian Bot as I'm figuring that's the "from scratch" place
to start as finding a reprap owner that can make a set of parts for me
in Canada has been a bit of a fools errand. The extruder sure seems
to be the key piece in a lot of the discussions and blogs though.
Any thoughts on the best way to put that bit togethers? The barrel
with a high-temperature resistor on it and an end nut rather than the
wire wrapped on copper and all that sure seems more elegant and
reliable, although few people seem ready to really say anything is the
way to start with for a new setup.
Dallas
