 ====How to Print a Part====
+  - At the Printer:
+    - Turn on the power if the printer is not already on
+    - Retrieve a clean build plate from fume hood #4, clean off any excess resin with IPA
+    - Open the printer door and remove the resin tank cover visually inspect the resin. Stir it up gently with a card if any discolored oily streaks are present at the surface
+    - Install the clean build plate, make sure it is firmly seated, and press down on the locking lever Close the printer door and move on to the software.
+  - At the Computer:
+    - MiiUtility:
+      - Open up the Utility application (found in the most recent MiiUtility version folder) (explain that the software does not install and instead runs locally)
+      - Import an .stl using the plus icon at the top right corner. Use the icons that appear on the right side of the screen to scale, move, and rotate the part to the desired orientation.
+      - Click the downward facing arrow icon to locate the part directly on the build platform
+      - Check the layer thickness displayed in the blue box at the top left corner of the screen. If you want to change the thickness, click on the box and a dialogue window will open up. (Note that the drop box contains more layer thicknesses than we have recipes, so check the available recipes beforehand)
+      - Once you are satisfied with the part placement, select the upward facing arrow icon (below the plus sign). This will bring up a dialogue box asking if you want to enter half-auto mode. Click “no”. You will then be prompted to name and save the .slc file
+      - The MiiPrinter window will automatically open
+    - MiiPrinter:
+      - If MiiCraft Ultra 50 with the name “Test #1” is present, it is okay to leave the IP address area blank
+      - Use the dropdown window under “Input” to display the correct .slc file, if it isn’t already. Note the name of the .mii file that will be created. Double check that the correct layer thickness is displayed
+      - Use the dropdown menu to select the resin and layer thickness that matches the desired recipe. The edit button can be used to duplicate and modify recipes.
+      - Double check the settings and click convert to create the .mii file
+      - Press “Launch to Printing”. The MiiController window will automatically open inside the MiiCraft Simple Browser window
+    - MiiController:
+      - If there are any issues with connecting, press the refresh button at the top left corner of the Simple Browser
+      - Click on “Select from PC” and choose the appropriate .mii file
+      - The print settings will appear in the left part of the screen, and the part itself will appear in the right part of the screen.
+      - Confirm the settings and click “Print”. A round progress bar will appear and the build plate will move into position
+=====How to Remove/Clean a Part=====
+  -At The Printer:
+    - Put on gloves and a lab coat. Retrieve a plastic transport container from the fume hood and line with an absorbent pad
+    - After the print has finished, allow several minutes for the excess resin to drip off the build tray into the resin tank
+    - Release the locking lever and carefully remove the build tray and place in the plastic transport Visually inspect the interior of the printer and wipe up any resin that may have accumulated on the exterior of the resin tank
+    - Replace the resin tank cover and close the printer door. This prolongs the life of the resin and prevents contamination or accidental curing
+    - Take the plastic transport container containing the build plate over to fume hood #4, being careful not to spill any resin. Immediately wipe up any spilled drops with IPA.
+  - At the Fume Hood:
+    - Open the FormWash IPA washing station (See resin wash SOP)
+    - Place the build plate with the part still attached into the basket
+    - Adjust the time settings to 20 minutes and start the cleaning cycle
+    - Once the cycle is completed, take out the build plate and remove the part over the absorbent pads in the fume hood.
+    - Place any contaminated waste in the yellow hazardous waste bin
+    - Clean the base with IPA to remove any resin and place in a clean transport container
+====How to Edit a Recipe:=====
+  - Let’s say you want to use a different layer thickness and therefore need a different recipe. Open up the MiiPrinter window and click the edit icon to open a new window. Click the duplicate window and rename it with the resin and the layer thickness. Adjust the settings in the menu and save to create a new recipe.
+====Accident Response====
+**Accident:** A user leaves a build tray or foreign object inside the printer when starting a
+print. \\
+**Printer Response:** A mechanical error warning displays on screen. Printer is not responsive to
+computer commands and requires a hard reboot \\
+**Solution:**
+  - Press and hold power button for 2 seconds, then release.
+  - A dialogue on the printer window will appear asking if you wish to power down. Press and hold power button for 2 more seconds to completely power off machine.
+  - Wait 60 seconds, and then press power button to start the machine. This will initiate an automatic homing process that will raise the build platform to the top of the printer enclosure.
+  - Remove obstructions and refresh computer connection in MiiController Window
+**Accident:** Scratching glass projection plate or Teflon surface of the resin tank \\
+**Printer Response:** Print Quality is poor \\
+**Solution:**
+  - Replace build tank
+**Accident:** Build tray is not installed \\
+**Printer Response:** New prints will not start, build platform stand immersed in resin. \\
+**Solution:**
+**Accident:** Chemical spill of IPA or toxic resin \\
+**Solution:**
