\begin{enumerate}
\item Your printer has been pre-calibrated and tested; however, after unpacking you will need to double check that everything is in order before you print.

\item You should set your printer on a stable, flat, and level surface large enough for extra space around the printer. Make sure your printer work space is clear of anything that could obstruct the movement of the printer. \textcolor{red}{Make sure there are no flammable fabrics or liquids near the printer space}. It is also best to not put your printer near a drafty window or air conditioner vent.

\index{end stops}
\item Check that the three mechanical end stops are aligned to contact with the respective ends. The mechanical end stops are small switches located at the home point of each axis.
(Fig. \ref{fig:axes}, page \pageref{fig:axes}; Fig. \ref{fig:xz_endstops}, page \pageref{fig:xz_endstops}; Fig. \ref{fig:y_endstop}, page \pageref{fig:y_endstop}).

\index{RAMPS}
\index{wires}
\item \textcolor{red}{Make sure none of the wires have come unplugged from the RAMPS electronics board}. If any wires have come unplugged in shipping or unpacking please see the reference image on the support page at \texttt{www.LulzBot.com} or \texttt{reprap.org/wiki/RAMPS1.4.1} to find where the unplugged wire(s) need(s) to be plugged back in.

\index{power supply}
\index{USB cable}
\item Unwrap the power supply, USB cable, and sample plastic filament.

\textcolor{red}{MAKE SURE THE POWER SUPPLY IS COMPLETELY UNPLUGGED BEFORE MOVING ON TO THE NEXT STEP}

\index{plugs}
\item Plug the loose black plug coming from the printer into the black plug from the power supply
(Fig. \ref{fig:ps_plugs}, page \pageref{fig:ps_plugs}).
\begin{figure}[hbt]

\caption{Power supply plugs}
\label{fig:ps_plugs}
\end{figure}

\item Set the AC power setting on the side of the power supply. \textcolor{red}{You will 
need to set it to \texttt{110V} or \texttt{220V} depending on your regional location. Failure to do so can destroy your power supply!}

\item Plug in the USB cable, B plug (square plug) side, into the USB receptacle on the printer electronics. Plug the other end of the USB cable, A plug side, into your computer.

\index{power switch}
\index{RAMPS}
\item \textcolor{red}{Make sure the printer power switch is turned off} (the circle side should be depressed). The LED on the power supply should not be lit. Plug in the black RAMPS power plug from the power supply into the matching black receptacle in the RAMPS electronics (Fig. \ref{fig:ramps_plug}, page \pageref{fig:ramps_plug}). Make sure the screw terminals on the plug are facing out from the printer. Now you can plug in the AC power plug from the power supply into an AC power outlet.

\index{spool}
\item Locate the plastic filament spool
(Fig. \ref{fig:spool}, page \pageref{fig:spool}).

\end{figure}
Locate and loosen the three wing nuts on the upper arms. Completely loosen and remove the 
three wingnuts and washers. Slide each of the three arms off of the screws 
(Fig. \ref{fig:spool_remove_nut}, page \pageref{fig:spool_remove_nut}).

\end{figure}
Turn each arm 90 degrees outwards from the spool until the arm is parallel with the lower arms. Replace the washers and wing nuts and tighten
(Fig. \ref{fig:spool_move_arm}, page \pageref{fig:spool_move_arm}).

\end{figure}

\index{wrench}
\index{pliers}
\item Remove the large wing nut from the back of the spool. Take off one washer leaving the other three on the spool mounting bolt. Now locate the spool mount arm on the top right facing the rear of the printer
(Fig. \ref{fig:spool_mount}, page \pageref{fig:spool_mount}).

\caption{Spool mount}
\label{fig:spool_mount}
\end{figure}
Slide the spool mounting bolt through the hole in the spool mount arm. From the back of the spool mount arm slide the one washer on to the spool mounting bolt and turn on the wing nut
(Fig. \ref{fig:spool_mounted}, page \pageref{fig:spool_mounted}).
\begin{figure}[hbt]

\caption{Spool mounted}
\label{fig:spool_mounted}
\end{figure}
Use an M8 wrench to hold the spool mount bolt head and pliers to turn and tighten down the wing nut. Tighten the wing nut tight enough to put pressure on the spool hub bearing.

\index{PTFE tube}
\item Locate the filament guide with attached PTFE tube
(Fig. \ref{fig:filament_guide}, page \pageref{fig:filament_guide}).
\begin{figure}[hbt]
\centering
\includegraphics[keepaspectratio=true,angle=0,height=0.4\textheight,width=1.0\textwidth]{filament_guide.jpg}
\caption{Filament Guide}
\label{fig:filament_guide}
\end{figure}

Locate the top most horizontal aluminum extrusion closest to the filament spool
(Fig. \ref{fig:filament_guide_nuts}, page \pageref{fig:filament_guide_nuts}).
\begin{figure}[hbt]
\centering
\includegraphics[keepaspectratio=true,angle=0,height=0.4\textheight,width=1.0\textwidth]{filament_guide_nuts.jpg}
\caption{Filament Guide Nuts}
\label{fig:filament_guide_nuts}
\end{figure}

In the extrusion you will find two loose t-slot nuts. The filament guide attaches to the printer by screwing in the two bolts through the filament guide into the t-slot nuts. First thread the two bolts into the t-slot nuts. Leave the bolts loose enough so the filament guide can slide back and forth across the extrusion. Set the filament guide 1.5-2cm away from the end of the lower arms of the filament spool
(Fig. \ref{fig:filament_guide_setting}, page \pageref{fig:filament_guide_setting}).

Once the filament guide is set in place, tighten down the two bolts.

\item Insert the micro SD card into the SDRAMPS shown in
Figure \ref{fig:sdramps}, page \pageref{fig:sdramps}.
