BLTouch probe acting funny
-
Ok so my build is coming along nicely and i've got all the homing figured out. However, whenever i go to do the auto bed compensation via the web interface, the z axis moves down, and the probe deploys without enough room. this causes the probe to hit the aluminum bed and fail to trigger. BUT when i do a regular homing routine, all is good. what did i goof up?

M558 P9 H1
Your dive height (H1) is only 1mm, which isn't enough room for the pin to deploy. Change it to 10 for starters and maybe reduce it to 5 if you think you can safely get away with it.
