[BUG] SKR 1.4 (non turbo) BLtouch not working #18053
Comments
I have a kind of related issue, but in my case, when trying to use the pins that are specifically put there for the BLTouch, leveling works but not Z homing. When leveling, the printer moves to the leveling position (center of the bed) and then just doesn't deploy the BLTouch and just says that that's Z=0. That's with this configuration:
If I try to use the Z_MIN_ENDSTOP pin instead (and activate EDIT:
|
I already have USE_PROBE_FOR_Z_HOMING enabled so that doesn't solve my problem im afraid |
This has been reported quite a few times. The simplest solution is to define |
TBH with the latest version of bugfix-2.x there is this feature explicitly for that reason ( I'll now look at @jamesrooke54's config. If I don't find the issues, I could send him my config, it's working now under the latest version of Marlin with TMC2130 drivers, the RepRapDiscount LCD and SD card also works. |
Okay, it looks like you really don't have the latest version @jamesrooke54! You have something from the BTT repo. I'd highly suggest you download / clone this repo instead, on the bugfix-2.0.x branch, port your config over and try again! You did add the |
Ok I'll try again with the latest marlin and see how I get on, apologise I didn't know the BTT one was that far behind your version |
Great, good luck! No problem 👍 |
Hi, my 3DTouch is working. I have modified Configuration .h //#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN #define Z_MIN_PROBE_PIN P0_10 // Pin 32 is the RAMPS default And this is the special Problem: you need to go to Folder Marlin - scr - inc - Conditionals_LCD.h in Line 586 original #if Z_HOME_DIR < 0 && !HAS_CUSTOM_PROBE_PIN its modified #if Z_HOME_DIR < 0 //&& !HAS_CUSTOM_PROBE_PIN Thats the Issue i have found it. |
@jamesrooke54 still an issue? |
To be honest I've just removed it, the fix is to use the z stop plus and it use the bltouch port but doing that makes me itch lol if there is a port for it then you should be able to use it |
Please test the bugfix-2.0.x branch to see where it stands. |

Bug Description
ok, im trying to get my BLtouch working on the SKR 1.4, the 1.4 has dedicated pins for the BLtouch so im using those, the BLtouch self tests when the machine starts and im able to deploy the probe and retract. but when I home all the X and Y move to 0 then the Z moves up and X and Y move to maximum
if I go into the auto bed level menu then z moves up by maybe 10 X and Y move back to 0 the bltouch pin deploys and z starts to move down but if I trigger the pin it doesn't stop and I have to turn off the machine to prevent a crash
I do not have z endstops install only the bltouch, I thought i would be able to figure this out but im just not experienced enough to know where to start
