### Basic Information: Printer Model: vz bot MCU / Printerboard:lpc1768 lpc1768 Version: v0.12.0-175-g7b490f3e Host / SBC aarch64, 64bit Version: v0.12.0-286-g81de9a861 OS: Debian GNU/Linux 11 (bullseye) Distro: MainsailOS 1.3.2 (bullseye) [klippy.log](https://klipper.discourse.group/uploads/short-url/r8onoGrvUsYinbw38uGDa31ME3w.log) (5.1 MB) [printer.cfg](https://klipper.discourse.group/uploads/short-url/3vUTDIWzE8lmKDuqnpW20NNg3Xb.cfg) (5.0 KB) BTT skr ver 1.4 I try to get a 3d touch to work. But the moment I trigger it it starts blinking and goes in to error mode. I freshly installed the probe and connected it to my SKR v1.4 board. Then I added the line in printer.cfg [bltouch] sensor\_pin: ^P0.10 #Probe control\_pin: P2.0 #SERVOS x\_offset: 37.10 y\_offset: 9.25 z\_offset: 0.00 When I run the initial test from [BL-Touch - Klipper documentation](https://www.klipper3d.org/BLTouch.html) Everything works as expected until the part where I should test the trigger. The moment I try to trigger it pulls back it starts flashing blue and red. After reset it works normally except the trigger doesn’t work. one odd thing I experienced further was when included the [safe\_z\_home] part the the z axis moved down further and further instead of up for homing. ---

For the 3Dtouch is not a genuine BLtouch, you may have a look on this: [https://www.klipper3d.org/BLTouch.html#bl-touch-clones](https://www.klipper3d.org/BLTouch.html#bl-touch-clones) ---

Hi, did you check (double-check) your wiring? Wiring corresponds with settings? ---

Yes triple checked wiring. Especially because sensor servo works with up down movement ---

Ok I found a solution. [Folowing this Blog post.](https://deepcorelabs.com/3d-touch-bl-touch-clone-klipper-fix-for-ender-3/) Just tried different combinations of: ```auto stow_on_each_sample: False/True probe_with_touch_mode: False/True pin_up_reports_not_triggered: False/True pin_up_touch_mode_reports_triggered: False/True ``` For me True/False/True/False worked ---
