*October 2015: Both extruders fixed and working. Upgraded software on both computers upstairs and enabled both extruders on the Makerbot. Made a cardstock and copper tape pad replacement for the defunct front panel controls. Diagnosed and removed SMD Mosfet for the heated build plate and swapped in the Mosfet from the extra output on the control board. Replaced and rewired broken left extruder fan with a 12V fan; should be 24V but works fine. Diagnosed bad temperature sensor and main connector contacts on the heated build (HBP) plate; replaced HBP with the spare. Modified the spare heated build plate to used heavier gauge wire and spade connectors to avoid burnout as in previous HBP.
