Ender3 PRO with Mainboard 4.2.7 and BLtouch v.1

Hi, yesterday I installed on my Ender3 PRO with Klipper an old BLtouch V1 that I wiring with mainboard following this scheme:

When I send G29 command to the printer, I see that X and Y axis go to ZERO position and Z axis go to center of the bed, the BLtouch release the probe and when touch the bed stop, it rises and then descends again to stop after touching the plate with the probe for the second time.
At this point, though. klipper gives me this error: “BL touch failed to raise probe”.
I am writing my printer.cfg below, hoping you can help me

Thanks very mutch and ciao

Remove pin_up_touch_mode_reports_triggered: False and follow the template / information provided when you opened the topic.

Thanks Sineos, the problem was the code “probe_with_touch_mode: True” (probably my BLtouch is a clone); I removed it and now all work fine.
Now I’m searching tutorials on how manual calibrate the bed and then on how use mesh bed.
If I understand right, before I must calibrate the bed manually using the paper near the four screws and then I can use the probe to compensate for small difference to level bed, right?
Thanks again and ciao
