G31 P500 X0 Y0 Z0.445 ; set Z probe trigger value, offset and trigger height
Don't forget to set your XY offsets for the BLtouch. As it is now, it thinks the BLtouch is exactly where the nozzle is.

@Phaedrux
i have not set that yet, but i will after the printer is rebuilt Squared and finalized .and again Thankyou for your patience and help on this !!!!
-
No problem.

@Phaedrux
are you aware of anywhere i can download differnt macro files for differnt things, fully auto scripts, manual stuff.... dont care what they are, just want to find, learn, modify , try things out see what i can do with this printer. if you have any stuff you can pass on to me , please send me a file with a side of everything

You can take a look at mine if you like.

@Phaedruxnice, Thanks this gives me hours of hair pulling fun

If you're on RRF3 P7 should be P0

M500 P31; save results
Does it work if you put a space between the P31 and the ; ?
The only issues I am aware of with M500 is that it's currently not supported with the Duet 3 when used with a Pi.
Do you get any error messages if you send M500 by itself?
If you delete your config-override.g and send M500 does it get created?'
Actually, looking again, it doesn't look like you're using G30 S-3 to measure the probe offset with this macro, so M500 P31 isn't going to do anything here. What are you expecting it to save?

@Phaedrux
i moved the m500 and m501 below the line under the 501, seens to work and generate the correct offset and save it in a newly created config override file correctly......as i deleted to test with m32
verified by homing z, droping the table and baby stepping up till the probe is triggered. the z axis ,matches what was automatically storedno error message when send m500.

Since you haven't changed it with a G30 S-1 it's just saving the same value as before. There is no reason in this macro to have M500 or M501

Well it will stay in effect until the motors are de-energized. It should stay leveled through a G28 unless you're changing the position of individual motors in your homeall.
G30 S-1 ; set Z0 position with the probe M402 ; retract probeDon't do that. The G30 S-1 is only for determining your trigger height. You don't need or want to do that after you've done the tilt correction. Just do a single G30 at the center of the bed to redefine the Z0 position because the tilt correction will change it slightly. Trigonometry and all that.
If your G28/homeall homes the Z axis, you don't need to do that again at the start of the leveling points. Just after.

G30 ; set Z0 position with the probe
M402 ; retract probeAlso keep in mind that the tilt correction for the bed is only in one axis. It can't correct for tilt along Y. You might also need to run the G32 a couple times to get the tilt completely corrected, and depending on the repeatability of the probe you might end up bouncing around in the noise. So try and get it leveled up as best as you can manually to begin with.
After it's all leveled you may want to run a G29 to get a heightmap of the bed surface itself to see how it looks.
