BLTouch Installation

BLTouch Mount for Ender3V2 –
Use the two screws provided by BLTouch to screw it in.

If you are using a different extension wire, please pay attention to the wire colors above. Match them based on colors from left to right according to wires on BLTouch


As of 31st of July, Creality removed the 1.1.6 BLTouch firmware from their official site. For whatever reason it might be, below is a mirror link to the previous firmware v1.1.1 BLTouch by Creality which works.

For Ender 3 V2 no bootloader intallation is required. Copy the firmware into your SD card and then slot it in, the printer will begin flashing once you reboot it. Do remember that you need a different filename each time you flash a new firmware eg. firmware1.1bin > firmware1.2bin, else the system will ignore it.

And remember to add “M420 S1 Z2” in Cura!

VERY IMPORTANT Add M420 S1 Z2; after the G28 in your start G-code
in the starting G-code of your cura profile. To enable leveling on every prints. As the current marlin for Ender 3 V2 is unable to make “leveling enabled” persistent after reboot.

M420 S1 Z2 ;Enable ABL using saved Mesh and Fade Height

This line of code always appear in other printer profile such as CR10SProV2/Ender5Plus where there is BLTouch built in.

What you might need

Personally I have added a printed BLTouch spacer to add some buffer between bed and nozzle, so BLTouch has more room for probing. If you are facing issue where nozzle is hitting bed when BLTouch is probing, mostly caused by uneven bed (eg. sides nearer to hotend is higher), you might need to try adding a spacer. But do note that adding a spacer will make your z-offset at around -2+

Steps to produce a good leveling

  • As this firmware is provided by Creality, there is no AUX tool or Z-Offset Tool included. Please refer to CHEP’s guide for how you can level your bed with a piece of paper.
  • One of the important element of having a good bed leveling is Z-Offset. Get a good offset at the center of the bed, gauge it with an A4 paper. Use the Z-Offset setting to set closer or further from bed.
  • Once you got your Z offset, go to main menu and press “Leveling”. It will probe 3×3 points and save the mesh to your printer.
  • Done and start printing!
