One of the first items you want to print is your dreamer roll mount. You can see how that works here: http://www.thingiverse.com/thing:78741
Once this is printed, you can further configure your printer settings with the essentials calibration set. All of your settings should be spot on, as I have done this for all the printers.
Basic Gcode Commands:
G1 x0 y0 z0 - The G1 command tells your printer to go, typing in a axis after it tells it where you want to go, in this case, 0 for X, Y, and Z axis.
G92 z0 - The G92 command tells your printer to set it's base value. In this case, it would set your Z-Axis to 0 wherever the Z axis currently is. It will not move the axis.
All STL files for this printer can be found at the link below
