The X-axis and Y-axis limit switch end stops are fixed. The Z-axis end stop is
adjustable to allow for a wider range of adjustment when leveling the print board.

Please see Section V for more information on calibrating the Z-axis end stop, and
Section VI for more information on how to level the print board.

Printer Hot End Assembly

The printer hot end assembly is the mounted on the top of the printer and moved horizontally
along the X-axis.  The printer hot end assembly is comprised of two main components:  the
extruder motor and the hot end.  The extruder motor sits on top of the assembly, and it pushes
the  filament  to  the  hot  end.    The  hot  end  sits  below  the  extruder  motor,  and  it  heats  the
filament to the specified temperature.  The filament then passes through the hot end nozzle.
The hot end has a thermistor embedded which relays the temperature of the hot end to the
printer’s operating program which is referred to as firmware and is located in RAMBo board.
