Describe your issue:

Hi everyone,
I’m trying to make my 3D printer work with Klipper, so I followed every steps explained in the documentation.
Everythings work fine except the BLTouch that refuse to Home Z while executing G28.
Every configuration tests describe in the documentation sucessfully pass except G28.

  • BLTOUCH_DEBUG COMMAND=pin_up → OK
  • BLTOUCH_DEBUG COMMAND=pin_down → OK
  • BLTOUCH_DEBUG COMMAND=touch_mode + QUERY_PROBE → “probe : open” until I push the pin up then “probe : TRIGGERED”

When executing G28, the bltouch deploy and then stow after 1 second without any reason. It repeat it 3 times and the Z stepper doesn’t move at all.
I tried activate 5V mode (as I configured it in Marlin), activate probe_with_touch_mode, but nothing seems to make it work

My 3DTouch is a clone from Trianglelab and works fine with Marlin.

Does someone have a idea of what goes wrong with my configuration ?

Thanks

Hello @Moute69 !

So, do you have a BLtouch or a 3Dtouch?

There are clones that have to be processed a bit different than the genuine one.

Hi @EddyMI3D

Mine is a 3DTouch from Trianglelab.

I have read that documentation again and finaly find a solution that I missed on my first read :frowning_face:
Sorry for that

For those who have the same problem as me. I juste add
pin_up_touch_mode_reports_triggered: false

Thanks for your help
