You might want to look at:


a few more quid, but really nicely designed by someone who knows what
he's on about, judging from things like this:


(most of the rest of the reprap folk are busy gluing heatsinks onto the
insulated tops of the driver chips in the misguided belief that that
might fix their problems, so it's very refreshing to see someone
who can actually work out the underlying causes of problems.

Not that I know anything (good or bad) about the K8200.  A very quick
duckduckgo turned up this though:


which seems to suggest that it's not that accurate out of the box.  The
"rough around the edges" comment in this:


may be significant too, although I'd say that probably applies to all
reprap style printers -- they all seem to be open-loop, with end-stops
only on one end of each axis, so ... well that's another thing that
nophead has addressed:


If you don't mind rough-around-the-edges, then I have a mendel in bits
in the cellar that I can flog you :-)
