==== Overview ====
The frame is from a CubeX Duo (one of three donated by Mojo Coworking).  The printer ran on proprietary hardware and software and was difficult and expensive to maintain, so we decided to convert it to an opensource machine.  The hardware was replaced with an Arduino Mega and a RAMPS 1.4 board.  The firmware is Marlin.  We also replaced the extruder, hot-end, and z-axis endstop, and added a heated bed.

The control software on the laptop is Repetier using Cura as the slicer.

==== Safety ====
  * This is an open source printer.  Pay close attention to watch for any problems and turn off the printer immediately if you see a problem and report it.
  * NEVER LEAVE THIS PRINTER UNATTENDED!  While we are testing the printer, you must remain at the makerspace whenever using this printer to reduce risk of fire.  You may prefer to use the TAZ6 for larger prints for this reason.
  * The heated bed is not tempered or safety glass.  Abrupt changes on temperature could cause it to crack or shatter.  Keep the doors to the printer enclosure closed whenever the bed is heating or cooling (including during your print).  If you need to open the door to the enclosure, wear safety glasses.
  * Examine the printer before each use.  If it does not appear to be in safe working order, place a sign on the printer, report the issue, and do not use the printer.  If you are unable to determine whether the printer is in safe working order, or if you are unsure how to use the printer, ask someone for help.
==== Usage Instructions ====
  - Power on the laptop and open Repetier_Host from the Desktop.
  - To turn on the 3D printer, flip the switch connection the black and green wires next to the power supply.
  - In the upper left corner of Repetier, click the arrow next to the Connect button and select the RepRap_Marlin machine.  The button should change to a Disconnect button once connected.  If the button says Disconnect when you open the laptop, the laptop is already connected to the printer.
  - Load an .stl file using the Load button.  An image of your piece should appear in the 3D View tab.
  - On the right side of the screen, select the slicer tab.  The slicer should be CuraEngine, the Print_Configuration should be Slower_Speeds, the Speed slider should be set to Slow, and the Filment Setting for Extruder 1 should be PLA.  As ew use the printer and get other types of filament, some of these may change, but initially, these setting seem to give fairly good results.
  - When you have selected the correct profiles and entered your settings, click on Slice with Cura Engine.  You should then see an image of what your peice will look like on the printer.
  - If everything looks good, click on Print.
  - When your print is done, wait for the bed to cool down.  Then remove your print, turn off the printer using the switch connecting the green and black wires next to the power supply, and close the laptop.
  - Please report any problems or desired changes to the profiles to any board member.
