Just ordered some cool new parts from MakerBot!
With this installed, I shouldn't ever have to worry about the heat core resistors burning out! Plus, there's a thermal cutoff, which should be really nice, preventing the machine from overheating!
Will post pics and installation tips once the parts get here!
Also getting 1KG of their standard white ABS, but getting it on a spool, which should be very, very nice :-)
Sorry about the jumpy nature of this post... brain's not quite here at the moment :-)
