I've made a trial and phisically lowered the BLTouch by about 1mm....well, after that the nozzle raises from the plate about of another 1mm....it looks like the Z offset is "added" rather than "subtracted" from the nozzle height or that the BLTouch gives an "inverted" value....I think I've made some stupid typing error somewhere but I can't realize where
The BLtouch should be mounted such that the base of the probe body is approximately 8mm above the nozzle tip. This should lead to a trigger height of ~2mm. This is the range recommended by Antclabs themselves to ensure accurate probing and clearance of the pin.
Increasing the probe offset moves the nozzle closer to the bed, reducing it moves it farther away.
Did you try the M558 P0 trick?

Hi, no I didn't, I had few time today and I've mainly focused on try to understand how to solve the problem with the BLtouch...in the end I had to re-mount the vinda because I couldn't get rid of the error and the vinda works in terms of z offset....I didn't know about the 8mm I've always used it with almost 3-5mm...tomorrow I'll see if I have enough vertical room to mount it at about 8mm from the nozzle...thanks!
