Gathering Materials

As with any project you begin, it’s necessary to gather the appropriate materials. If you prefer to buy each component individually, rather than the kit, here’s what you need, assuming you already own an Ender 3 or Ender 3 Pro:

Now that you have all the necessary components, you can begin installing your auto bed-leveling system.

Here’s a simple guide on how to install your auto-bed-leveling system:

  1. Mount the BLTouch with the part provided in your kit or the one you 3D printed.

  2. Before you connect the electronics, first upgrade your Ender 3’s firmware so that it supports your new BLTouch.

    1. Turn your printer so that you can access and remove the electronics cover as well as access the mainboard.

    2. Plug the ISP end of your USB ISP into the appropriate plug and connect the USB side into your computer. A blue light should turn on next to the ISP connection on the mainboard.

    3. Download the firmware corresponding to your printer. Then, flash your printer’s firmware as directed by firmware’s included instructions. The application “progisp.exe” is included in the download and is what you use to update your printer’s firmware.

    4. After the new firmware has been uploaded to your printer’s mainboard, disconnect the printer and computer.

  3. Next, disconnect your Z-axis limit switch and replace it with the connector for the BLTouch.

  4. Finally, disconnect your screen cable and reconnect it via the Pin 27 adapter board.

Troubleshooting: Some people have had issues fitting the electronics cover back on after adding the Pin 27 adapter. Some have even tried bending the pins. If you believe it’s better to be safe than sorry, simply print a new cover.
