Former TA Saed made a video on how to use the 3-D printers in Lab 335.
Each printer has a Raspberry Pi attached to it via USB. These Pis are running an OctoPrint web server which is only accessible via the Skynet WiFi.
Summary:
Import the project STL into either Ultimaker Cura or Creality Slicer. Set the parameters and slice the file into a GCODE format for a Creality Ender-3 S1 Pro. Then, log into the Octoprint server and upload the GCODE file. Select the file you uploaded in the sidebar project list, verify there are no error bubbles, and click on “Print”.
Slicer Options:
Creality Slicer 4.8.2: https://file2-cdn.creality.com/file/dc05d27f3ee5efe47dab3e032899e37f/Creality_Slicer-4.8.2-build-254-win64.exe
