You can try improving the repeatability of the BLTouch by changing your M558 and G31 as follows
M558 P9 C"^io5.in" H5 F60 T6000 R0.2 A10
G31 P25 X41.13 Y2.69 Z1.543See if that helps.

So the new BLT settings didn't help. I am still getting differences at every single probe and maybe once in 7-8 I get twice the same reading.
Maybe this happens because I have flexible couplers on the Z ?
Now I am trying to figure out why my heightmap is always ~1mm up on the heightmap tab.
No matter what I am trying I am always ending with this....what I am missing?
I redid multiple times the z calibration using M561 , G92 Z0 , G30 S-1 and setting the new offset and always I end up with this. Maybe this also affect the mesh compensation?

I had the same heightmap offset problem a couple of days ago. The documentation is a bit ambiguous. I seem to have solved the problem by doing this in the calibration run (I use a macro).

That's something I was thinking that there is some residue code that can't be seen on files and messing everything. think I will just save the config and make a new sd card and see how the things are working. ...after I will try your code.

That could be part of it.

This would indicate that you're not setting Z0 correctly before running G29 to create a mesh.
When you're doing G92 Z0 you've moved the nozzle to touch the bed first, right?
The inconsistency could certainly be from movement in the Z axis couplers.

I am following the guide on dozuki
Cancel any currently active mesh compensation with M561 Use the X and Y jog buttons to position the nozzle over the centre of the bed Jog the nozzle down until it is just touching the bed or just gripping a sheet of paper. If the firmware doesn't let you jog it down far enough, send M564 S0 to disable axis limits. Once you have the nozzle touching the bed, send command G92 Z0 to tell the firmware that the head is at Z=0 Jog the head up by 5 to 10mm Send command G30 S-1. The nozzle will descend or the bed rise until the probe triggers and the Z height at which the probe stopped will be reported. If you are using a nozzle-contact Z probe, the trigger height will be slightly negative. For any other type of Z probe where the probe triggers before the nozzle contacts the bed, it will be positive. Repeat from step 5 two or three times to make sure that the trigger height is consistent. In Duet Web Control, go to Settings -> System Editor and edit the config.g file. Set the Z parameter in the G31 command to the trigger height that was reported. Save the file. Open config-override.g and check that there are no G31 commands in it. If you find any, delete those lines and save the file. To apply the new trigger height, restart the Duet by sending M999 or pressing Emergency Stop.The only difference is that I point the probe to the middle of the bed not the nozzle.

Probe pin to centre of the bed
Lower nozzle to touch the bed( paper method)

G28 ; must be homed first G30 ; Perform a single probe to establish Z=0 (should already be at center because of home)
This is a pretty ambiguous combination because we can't see what the homeall is doing to home the Z axis, and we have no idea what XY location the G30 is being done in.
The important thing to remember is that the Z0 position is set in the same XY position whenever you set it. Your homeall, homez, and any other time you use G30 must be in the same position before and after G29 is used to create or load the height map. This is because the shape of the bed may give you a different z height depending on the XY location.
-
In my case homeall.g looks like this (homez sets to the same position) ... But I think you also answered one of the ambiguities in the documentation i.e. what coordinate (XY) is the bed height relative to. Seems the answer is "Wherever you set your Z-home"? EDIT: which needs be the same as your Z=0 datum.?
G91 ; relative mode G0 H2 Z10 F200 ; raise head above Z probe trigger height G0 H1 X-240 Y-240 F3000 ; move up to 240mm in the -X and -Y directions until the homing switches are triggered G0 H2 X5 Y5 F600; move slowly 5mm in +X and +Y directions G0 H1 X-10 Y-10 ; move up to 10mm in the -X and -Y directions until the homing switches are triggered G90 ; back to absolute mode G1 X110 Y110 F2000 ; put head over the center of the bed, or wherever you want to probe G30 ; lower head, stop when probe triggered and set Z to trigger height -
Yes I made sure that every mesh starts from the same point....
Looking at the DWC now before I run this macro my home position was X-12 and Y-14 instead of the real X-6 Y-7 so I had something doubled in my steps. Now everything is normal only by running that macro.
I suspect there was something related to baby steps but I never went more then 3mm up/down during printing and it's just strange how it was exactly double compared with the original values.
Also tried to manually delete the heightmap , any mesh level maps I had saved and using G29 S2 with no resultNow I am trying to figure out how I can do a mesh level starting from the centre of the bed instead of the home position because my centre bed is the lowest point.
G28
M98 P"move_probe_center _bed.g"
G29 S0
will work or how it will be the best?
Making specific points for probing on the bed.g will work?Thinking that the lowest point will be under Z0 and I may not get the nozzle down enough...or it will compensate below Z0?
-
I am back on the same situation....tried to do a print and there was no mesh compensation applied. after I cancelled the print I did a G29 and my height map is back "in air" with ~1mm......time to reset everything and start from scratch
-
Maybe reshare all your gcode files including start gcode
-
........and now my home position is again at Z-12 Y-16 instead of X-6 Y-7 but visual is where it should be.
I have no idea why this is happening......I will keep the same config for couple more days maybe there is a bug or something.......; bed.g ; called to perform automatic bed compensation via G32 M561 ; clear any bed transform G29 ; probe the bed and enable compensation ;G30 P0 X42 Y0 Z-99999 ; probe near a leadscrew ;G30 P1 X358 Y0 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors ; config-override.g file generated in response to M500 at 2020-12-31 13:29 ;nothing on here ; Configuration file for Duet 3 (firmware version 3) ; Configuration for Chiron+Titan Aero+Volcano+BlTouch+ SBC Pi4 ; executed by the firmware on start-up ; General preferences G21 ; works in mm G90 ; send absolute coordinates...

There are some problems in there. I'll reply again when I'm back at my PC later.

It's a bit hard to tell from your copy and paste which files are which. It looks like the homing files got pasted into the config.g portion? And that all might be in the middle of bed.g?
M98 P"homeall.g" ; run home all command G30 P0 X42 Y0 Z-99999 ; probe near a leadscrew , the left one G30 P1 X400 Y0 Z-99999 S2 ; probe near oposite leadscrew and calibrate 2 motorsWhere is that from?
In homeall.g don't use M280 P0 S90 to retract the pin. Use M402 instead. That way the firmware is made aware of the pin retraction.
Also in homeall and homez,
G30 H1 Z-455 F360is not a valid way to use G30. It's just G30 by itself. The speed is set by the M558 command in your config.g. The H1 etc etc will be ignored probably. -

This is just a macro I am using to home all and level the gantry. My plan is/was to use this and after that to run G32 or just a single probe and load height map. I level the bed with the stock endstops because I know they are in the same spot always and to make sure the things are as square as possible. After I am doing this I disable the stock end stops and use only the BLT......because the stock endstops are about 7-9mm above bed surface...still trying to figure out how can I use them always and use the BLT only for mesh compensation
In homeall.g don't use M280 P0 S90 to retract the pin. Use M402 instead. That way the firmware is made aware of the pin retraction.
Ok I will change this.....

In homex: The G1 Z5 should have H2, otherwise it will complain if Z isn't homed first. Also remove the G90 and second G91. You just need to be in relative mode for those moves. Also, if you're using stall detection on X and Y, it's pointless to do a back off and second homing pass. A single fast homing pass is all you need.
;homex.g G91 ; relative positioning G1 Z5 F6000 ; lift Z relative to current position G90 ; absolute positioning G1 H1 X-405 F1800 ; move quickly to X axis endstop and stop there (first pass) G91 ; relative positioningIn homeY the same thing goes for the G1 Z5 move needing H2. And the removal of the G90 and second G91 for the same reason. Also here if you are using stall detection, only ne pass is needed. If you are using an endstop switch, then the back off move should NOT have H2.
;homey.g G91 ; relative positioning G1 Z5 F6000 ; lift Z relative to current position G90 ; absolute positioning G1 H1 Y-415 F1800 ; move quickly to Y axis endstop and stop there (first pass) G91 ; relative positioning P4 P500 ; wait 500ms G1 H2 Y5 F6000 ; go back a few mm G4 P500 ; wait 500ms G1 H1 Y-415 F360 ; move slowly to Y axis endstop once more (second pass) G1 H2 Z-5 F6000 ; lower Z again G90 ; absolute positioningIn your homeall and homez you should be positioning your probe at the center of the bed before sending G30.
You don't need all of the G4 pause commands in there either.
Your bed.g and level gantry macro could be the same thing. And I would leave G29 as a separate command rather than using it in G32 (bed.g)

Thanks....I will upload the new files and see how it's working. I will do 2 separate sd cards....I will use them in a fresh install and on the old one . Just testing to see if this will fix the map height thing.

Above - you said " If you are using an endstop switch, then the back off move should NOT have H2."
Can you explain that please. I'm trying to better understand the documentation. I can see that H0 could be used for the backoff move since we now have a "home" for the axis. The documentation for H2 says
"H2 Individual motor mode. X refers to the X motor, Y refers to the Y motor, and so on. Normally used with relative motor coordinates (see G91).is used for a single"
This description would seem to apply to this situation - albeit may be redundant in the context of a backoff move. Basically - you said "NOT" and I'm seeking to understand if there is a negative here.One last thing (may be related) - is it "good practice" to issue a G90 at the end to avoid any potential, accidental issues with subsequent positioning commands ? Or does the homing move H1 automatically revert the printer to absolute positioning ?
