I recently installed the 4.0.3 build in an attempt to get my BLTouch Smart V3 to work. I have checked the connections and it seems the BLTouch works when i self test, probe up, down. It is a solid red when i start it up, however, i cannot level because the printer will no longer home the Z-axis correctly.
I can control the Z-motors by octoprint, as well as in the manual controls, however the Z-axis homing button will not work, and any homing attempt made by either the auto-bed leveling, home all axis, sensor z-height, homes the X-Y axis correctly then crashes the nozzle into the bed with a setting of -270mm in Z, I let it go once and it restarted advi3++ after crashing the nozzle for about 15 seconds.

also something I noticed was the bltouch sensor in the top bar of the lcd screen is grey and not orange as i see in a lot of your screenshots. I haven’t been able to figure out what that means.
any help would be appreciated.
