Problems with BLtouch
June 21, 2024 10:45AM
HI All,

Firstly I'm totally new to editing Marlin This is my first attempt.

I'm trying to update my Ender 5 Pro, it has a Creality V4.2.2 board and a CRTouch.

I've downloaded the Marlin Bugfix 2.1.x files and the latest Configurations-bugfix-2.1.x selected the 4 files for the creality ender 5 pro, crealityV422 and copied them into the Marlin folder.

I've enabled "#define ENDER5_USE_BLTOUCH"

compiled and installed it onto the 3D printer, but when I try to home the machine the x & y work fine, but the Z just causes the bed to lower, the head to go to the centre and the probe on the BL touch to deploy and stow a few times without moving the Z axis then it just stops.

I know I must be missing something but I've spent close to a day searching google and here for some info but it's hard to find something when you don't know what to look for.

any help is greatly appreciated

Thank you
Robin

The line #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN

this line says you plugged the CRTouch into the Z_MIN endstop plug

Did you do this or did you plug it into the 5 pin bltouch plug?

If you plugged it into the 5 pin bltouch port you need to comment out //#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
