The Bowden extruder notion seems to have more trouble with ooze: half a

Still looks like 25 seconds/layer or thereabouts. Certainly a big
improvement
over earlier designs, though.

Ed;
The fundamental problem with a RepStrap made from a typical milling
machine is speed: my rather customized Thing-O-Matic prints reasonably
well at 30 mm/s and makes rapid motions at 250 mm/s.
Interesting comment - my KX1 config is not with me, but as it has a Gecko G540
and runs 48v
I regularly run my Thing-O-Matic at 120 mm/sec while feeding (I can do 160
but the quality suffers), and travel at up to 200 mm/sec. Most older ToM's
and cupcakes ran at 30 mm/sec, since the earlier firmware did not use
acceleration, leading to missed steps at higher speeds.

That certainly puts it in the running!
What are the acceleration rates on the dedicated machines?
Given my heavy custom build platform and 12 V stepper supplies, the
accelerations aren't all that
Hi all;
Noted lots of interest in 3D printing, and have saved the emails.
I do find it a bit confusing, (RAMPS, Mendel, other new words) and am wondering
if anyone is working on a web page to provide a put an extruder in the
spindle, and 3D print web page for Linux-EMC?
I keep thinking about

Why would anyone who owns a mill buy a reprap kit? With your
knowledge of linear motion you could build a far superior machine in
an afternoon :-)

Michael Joyce just completed a kickstarter project for a 3D
printer, he got $510,000 in one month. He now has to deliver
about 180 systems. This
