How to install a BLTouch on a Creality Ender 5

If you would like to install a BLTouch to your Ender 5 and don’t know how? Well look no further! Here is a video showing you the steps you need to take to install this auto-bed leveling system! Take a look!

I second this video.
It has all the info you need.
That’s the one I used. It was easier than I expected.

There’s a few things to notice.
-The BLTouch will replace your z-stop sensor. So you can unplug that cable.

  • Sometimes the "needle"of the BLTouch will stop working. Maybe because of dust or debris that got there. Just turn the printer off, move the needle up and down manually a few times and you’re good to go.
  • Don’t forget to upgrade the firmware.

One thing missing in the video is the need to update the firmware. You will need to find the latest marlin firmware to install.

Personally I did have alot of issues after installing Marlin 2.0 so instead I installed TH3D and everything worked instantly.

Teaching tech has a great video on the install.

I have the 5 pro.
I’m really confused. I know I don’t have something in the firmware correct.
Auto home works, all BLtouch functions seem to work. I don’t understand how the meshing works. It doesn’t activate before a print (with the standard cura code found below, just added G29), and also, when I go to “Level Bed”, it goes to the front left of the printer, seemingly skipping the whole leveling the bed process.

I’ve flashed the firmware with
#define NOZZLE_TO_PROBE_OFFSET { -43, -7, 0 }
#define NOZZLE_TO_PROBE_OFFSET { +43, -7, 0 }
there is no difference between the two, leading me to believe that it isn’t initializing somehow.

I’m following this guide.
