Open the 3DWOX application on your computer and ensure that it says the name "STEM Room Printer" or something similar on the left side (this is the name you chose earlier). Wait for it to connect. If it doesn't connect, ensure that the printer is on.

Press "Load" on the left hand side. This should open the file explorer, find your .stl file that you want to print and hit open.

In the top right corner, there should be a prediction for how long the print should take. In order to reduce the print time or quality, you can click on the settings icon on the left bar of the slicer. From there, you can select different infill quantity, shell density, speed, and print quality. Their effects on the print are relatively self explanatory. If you want to know more about any of these effects, you can google them.

Once you are satisfied with the settings, press the "Print" button on the right bar. At this point you should make sure that the printer is operating as it should, and be sure to monitor it either in person or through the web monitoring tool.
