Date	Modification / Problem
12/06/2013	The printer's extruder had a meltdown. Ian replaced it and it appears to be working well.
09/04/2013	The printer needs an extruder
09/10/2013	Extruder frame mostly assembled, end stops obtained and attached to mounts, arduino w/ driver obtained. Next steps: Print large extruder gear, assemble and attach extruder, attach and wire endstops, attach and wire arduino. Also note: We need to add a bearing to the extruder and switch the carriage sides.
02/17/2014	The three brown wires linked PCB and nozzle caused some short circuit so that the PCB was overheat and COM port couldn't recognize it. Solution: haven't fundamentally solve the problem, just shaking the wire so that it no longer short circuit. Other problem: the nozzle could correctly arrive the position of the main printing part, but sometimes it misses the supporting material's position (it means the same layer the part I want to print is perfect but just the supporting material could not put on the layer below it but put on the aside.) So I think the reason why it happened was related to the programming, the subroutine of motors working for support material may have some wrong calculations.
