==== Demonstration ====
The student will need download, setup, and successfully start a print of their choice, providing it is within reason and Prototype Lab guidelines. If possible, they should stay as long as possible in case a print fails, which will be an opportunity to teach them basic troubleshooting of the machine.
==== General Procedure ====
Picking a Model:
Once you have a model you would like to print (which you can find on either thingiverse or model yourself), you will be using a software called PrusaControl to slice your .stl files into a .gcode file, which the printer will interpret and print your model from.

When all those settings are complete, you can click "Generate" in the bottom right corner, and PrusaControl will give you a time and filament estimate for your print. If they seem reasonable, you can save the newly "sliced" .gcode file to the SD card that will go into the printer! If not, you can always go back and adjust the settings to fit your time and/or filament needs.

Starting A Print:
Once you have the gcode file on the SD card, put the SD card into the Prusa (on the left side of the orange menu), and turn the printer on. The printer will read the SD card and initialize itself, then you can start. In the menu, there is an option you want called "Print from SD Card". That will take you to a list of all the .gcode files on the SD card. Search until you find your own, and select it. Make sure there is enough filament on the printer for your print, or it will fail midway!

For smaller prints, you want to make sure to watch the print until it is around 30% completion, which is given on the menu screen as the Prusa is printing. For bigger prints, it takes a longer time to get to 30%, so it is recommended to watch it until 10%-15% completion. If the print contains a lot of support, it is wise not to run it overnight, since lots of support on certain prints can cause failure more easily.

Finishing A Print:
When the print completes successfully, the Prusa will delightfully present the print by moving the print bed forward, and the extruder will go back to the homing location. On the menu screen it will display how long the last print took, and the other normal settings like the temperature of the print bed and nozzle. To get the print off of the bed, take the magnetic steel bed off and bend it just slightly to pop the brim of the print off of the bed. From there you can take the print off carefully by hand.

Put the magnetic bed back onto the Prusa, and if there are no more prints needing to be done, power it off.

Loading New Filament:
When the printer runs out of filament, typically you'll want to find a shop aid to help you change the filament. All you need to do is go to the menu, select the "Unload Filament" option, and the printer should start heating up. Once it heats up, it'll unload the filament and you can pull it out of the extruder.

As for loading new filament, find the option in the menu labelled "Autoload Filament", and the printer will walk you through the instructions for loading the new spool of filament.

Pausing or Stopping a Print:
To pause a print in the middle of the job, press the knob and it'll pull up a printing menu. There are two options near the bottom, "Stop Print" and "Pause Print". If the print is failing, you definitely want to stop it. If you need to change filament or think you can save the print before it fails anymore, you can pause the print.
