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

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:

Hi,

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

4

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

5

Yes but didn’t solved it

Ok I found a solution. Folowing this Blog post. Just tried different combinations of:

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
