I'm not familiar with the bltouch: Could you show the way you wired this up or what instructions you followed?
How do you know PB6 and PB7 are the correct pins?
Hey jookia. I help him with this Board (i am the creator and this Board work with this Pins). I never seen this Kind of error, that the bltouch goes up and down. @dog2bert can you Post the video with this pin movement?
Can you try testing the bltouch using https://www.klipper3d.org/BLTouch.html instructions?
Here is the video: https://youtube.com/shorts/tg0fCxpEp0Q?feature=share
It looks like the probe is going up and down in its idle state?

Yes, it will go up and down until I trigger it down. Then when I trigger it up, it goes back to up/down.
The immediate thought I get is that the signal is left floating when not pulled down.
Could you swap your control and sensor pins on the the board and in Klipper?

Switching the wires and config it had the same behavior.
I added this line to the bltouch config: pin_up_touch_mode_reports_triggered: false
and now it will go down during homing z axis, and stop when triggered, but gets this error after:
!! BLTouch failed to deploy
Hmm. I don't have a bltouch to test. Could you try the other Klipper options in the article I linked please?

I try the following config on my catboat install on BTT PAD7 on a Kobra Max, with the MakerPanda board for Stealthburner.
[bltouch] sensor_pin: !PB6 control_pin: PB7 pin_up_reports_not_triggered: False
probe_with_touch_mode: True
speed: 20.0
samples: 3
samples_tolerance_retries: 3
stow_on_each_sample: false
Z_offset: 0
The down command will work, but up command makes in oscillate up and down constantly. Homing, G28, BL touch failed to deploy when it get to the z axis home part.
