MakerBot Note :

If you haven't specially calibrated your thermistor settings, you might have to tweak the temperature settings in skeinforge to get the plastic soft enough. In my machine, the extruder jams for all temperatures lower than 230C. So, I had to go deep into the skeinforge-raft settings and make sure _all_ extrusion temperatures are above 230C.

warning : 230C may be more than enough to melt your insulator barrel if you are using the white PTFE part that ships with the kit. I bought a PEEK barrel from MakerGear and am currently praying to various gods that it does not suffer the same sort of failure at my PTFE barrel.
