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
