I loaded the new firmware and also had issues getting up to the right
temperature.  My extruder was set to 230 but only ever got to 175, and
my platform was set to 100 but only got heated up to 75.  Rolling back
to the previous extruder firmware returns my Makerbot to working
order. Anyone have any idea why the new firmware has these issues?
