Read through this page in its entirety before operating the Ender3v2. This printer does not work like the Ultimaker 2. This printer is running Klipper Firmware and prints are started through a web interface called OctoPrint.

Before you print

Check out the resources provided in 3D Printing At Hive13, primarily the Learning Resources section.


Operating Instructions

  1. Slice your .stl file in a Slicer. See 3D Printing At Hive13 for more information, but Cura or PrusaSlicer are recommended with the default Creality Ender3v2 profile.
  2. Go to in a web browser
  3. Log in with the following credentials username: Hive13 and password: 3dprinting@Hive13
  4. Ensure that the printer is connected to the printer /tmp/printer
  5. Drag and drop the gcode file that your Slicer output to the left side of the web browser.
  6. Click the printer icon on your new file

What do I do if I screw something up?

First, that's okay! 3D printing is a real P.I.T.A. But, failing, learning, and trying again is just a part of the process.

Second, abort your print on OctoPrint by clicking the Cancel button underneath the progress bar and then follow the build removal directions. If you're not sure why it failed ask on Slack and/or the mailing list, or DM User:Heath

If the nozzle clogs, let us know in Slack and/or the mailing list, or DM User:Heath

Build Removal

Allowing the print bed to cool completely. When you go to the Temperature tab on OctoPrint, the both temperature should read around 25-26 degress. This should make removing prints easier. If they are still difficult to remove then use the largest pair of channel locks you can find and grip the print firmly. A simple twist should pop it off in one piece. You can also try heating the build plate from the back side with a heat gun.

We DO NOT recommend the use of scrapping the bed plate to remove your print, but if you must... always scrape away from you. Prints tend to come off suddenly and with little warning. If you don't follow these instructions your print will become exponentially more expensive, as it will involve a trip to the emergency room and stitches.

Changing Filament

To remove filament

  1. Use the Octoprint UI or the LCD controls on the Ender 3 to set the hot end temperature to the filaments melt point (Eg: ~200 C for PLA)
  2. Wait for it to come up to temperature
  3. On the extruder motor, press the spring loaded lever to release tension on the filament, and gently pull it out.

To insert filament

  1. Confirm setpoint for the hotend matches the melt temperature for the filament I am about to insert
  2. Trim the end of the filament to a point to make it easier to thread into the extruder
  3. On the extruder motor, press the spring loaded lever to release tension on the filament, gently feed the filament into the bowden tube through the extruder. Continue to feed filament until I start to see plastic coming out of the hot end.
  4. In the Octoprint UI or via the LCD controls, instruct the Ender3 to extrude 30-40 mm of filament

Material Compatibility

Again, please refer to 3D Printing At Hive13.

The Ender 3 v2 uses 1.75mm nominal diameter filament. In it's current form (as of 08/05/2021) the Ender 3 v2 CANNOT print anything other than PLA. You can attempt to use any PLA that you desire, but Microcenter does carry a good amount of Inland PLA which works well.

Other good brands of filament include (but are not limited to):
