Calibrating Z-Offset With A BLTouch Bed Levelling Probe
Why 3D Printing Stack Exchange recommends it
3D Printing Stack Exchange users link it as a step-by-step guide for setting the probe Z-offset when a BLTouch or similar probe is misbehaving or being set up.

What it is
A short tutorial from the 3D Maker Noob channel showing how to calibrate the Z-offset on a BLTouch auto bed levelling probe. It walks through the Marlin G-code steps (M851, M500, M211 and so on) and uses a sheet of paper under the nozzle to find the true Z zero.

I think I fixed everything. What I did is I used this guide < [this video] > which was a guide by makes'n'breaks on setting the probe z-offset using pronterface and then reverted to the original firmware that was on this page<github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/tree/master/…> Which was the marlin firmware for bltouch for z homing for my mainboard.

This is the best Z offset calibration video in my opinion because they do everything in pronterface making it printer/firmware universal. [this video]

My G29 command reports +0.178 +0.281 +0.830 -0.614 -0.012 +0.371 -1.208 -0.849 -0.351 So should I tighten up the screw of the bed, close to 0,0 position or loosen it? I have a feeling that when I loosen it, it gets away from zero and I expect the opposite to happen. For bed leveling i use a capacitive probe and after playing around with the screws here is the result +0.406 +0.127 +0.411 -0.161 -0.007 -0.041 -0.572 -0.652 -0.668 Finally the leveling process was found here [this video] But the question remains. The value -0.572 corresponds close to 0,0 ?

Working on getting my Anet A8 upgraded with some extra toys and although the sensor works, I can't get it to home correctly. I'm looking for some assistance to home the X in the center. The probe is working and showing results, but when homing, it does not home to center (SAFE_HOME is turned on, Y homes to center but X is about 3/4 from endstop) and the Z offset always reports as 0 when using M851. There is a clear gap of about 10 mm between the bed and the nozzle after G29 is ran. I'm using the following mount [LINK] : [LINK] Bed is anycubic ultrabase 220*220 I have been using a combination of E3D configuration documents, [LINK] and [this video] to try and get it working.
