[edit] How to Print

  1. Find or design an STL model to be printed.
    • Thingiverse is a massive repository of free STL files.
    • TinkerCAD is a simple, in-browser CAD program.
  2. Open this model in a slicing program.
    • The computer next to the 3D printer has both Cura and Slic3r installed.
    • Cura is recommended for new users. It is easy to use and has a good preset for the Creality Ender 3.
    1. Edit the slicer settings if necessary.
    2. Reorient or scale the object if necessary.
  3. Slice the model and save gcode to Micro SD card.
  4. Level the bed.
    1. On the printer select Print From SD and locate CHEP_Ender_3_bed_level.gcode then press the button in to print.
      • The gcode file is available here in case it gets deleted.
    2. Adjust the knob on the front-left corner so you can get the paper between the bed and the nozzle and move it around with slight resistance.
    3. Repeat this process with the other 3 corners.
  5. Insert the Micro SD card into the printer.
  6. Press the button then scroll to Print From SD and select your gcode.
  7. Allow the printer some time to heat both the bed and the hot end.
  8. Watch the first layer to make sure the filament is flowing well.
    • If the lines are too thin or nonexistent you may need to adjust the knob(s) to bring the corner(s) of the bed down away from the nozzle.
    • If the filament is not adhering to the bed you may need to adjust the knob(s) to bring the corner(s) of the bed closer to the nozzle.
  9. When the print has finished remove the object from the bed.
    • If the object was printed on a flexible bed remove and bend the sheet to make removal easier.
  10. Remove support material with wire cutters or by hand.
  11. Clean up and throw away filament scraps and support material.
