Auto leveling questions with toolboard

@pelikán-jiří
you're missing a ; in front of Z-Probe Bltouch in your config.gyou're missing x and y offsets for your bltouch in config.g
G31 P500 X0 Y0 Z1.6
you're homez and homeall haven't been adjusted as described here https://teamgloomy.github.io/skr_rrf_e3_bltouch.html#files-to-modify

I have replaced the data as stated in the link. But unfortunately I don't know much about it, how do I make homeall work? Should I change something in config.g?;Homez ; ################# Home Z Preparation ################ G91 ; Relative mode G1 H2 Z5 F5000 ; Lower the bed G90 ; Back to absolute positioning G1 X0 Y0 F10000 ; Move to the center of the bed. Adjust to the co-ordinates required for the centre of your bed ; ################# Home Z Preparation ################ M558 F250 ; Set the probing speed G30 ; Probe a single point M558 F30 ; Set a slower probing speed G30 ; Probe a single point
;Homeall M98 P"homez.g"

you need to change that to be the centre of your bed.
If its an ender 3 thats typically around X115 Y115 -
@pelikán-jiří and if you're just oing to call homez then homeall should look like this
; homeall.g ; called to home all axes ; ; generated by RepRapFirmware Configuration Tool v3.1.10+4-LPC on Tue Jan 19 2021 17:25:01 GMT+0800 (中国标准时间) G91 ; relative positioning G1 H2 Z5 F6000 ; lift Z relative to current position G1 H1 X-240 Y-240 F1800 ; move quickly to X and Y axis endstops and stop there (first pass) G1 H2 X5 Y5 F6000 ; go back a few mm G1 H1 X-240 Y-240 F360 ; move slowly to X and Y axis endstops once more (second pass) G90 M98 P"homez.g"

Thank you very much, at the moment the head always stops roughly in the middle of the bed just above it. But I don't know why, but the meshgrid setting doesn't work. I have the dimensions entered, but the probing always starts outside the bed. -
@pelikán-jiří have you set the X and Y offsets of the bltouch?

Yes set. But suddenly it stopped working.
; Z-Probe Bltouch M950 S0 C"servo0" ; create servo pin 0 for BLTouch M558 P9 C"^probe" H7 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds G31 P500 X44 Y0 Z1.6 ; set Z probe trigger value, offset and trigger height M557 X45:230 Y40:215 S40 ; define mesh grid

I tried to find the error, but I have everything set up, but the meshgrid still doesn't work.
-
@pelikán-jiří how far off the bed is the first probe point?
-
@jay_s_uk
About 24 mm away. And I have it set to x60 -

About 24 mm away. And I have it set to x60And bed leveling also works unevenly, don't you know what the problem might be? I have already managed to start a functional autoleveling, but when I start printing, one side of the bed is too high and the other too low, because the motor balances the bed incorrectly.

the results of M122 and M98 P"config.g".
I think if you send M98 P"config.g" you'll see some errors that your pinnames being used for the BLtouch are not correct.
C"servo0"
C"^probe"Those are not valid pin names.
zprobe.in
. is correct.
For the servo where are you actually connecting the yellow wire of the bltouch? -
@phaedrux they are correct for an SKR-RRF-E3.
Pin names are here https://teamgloomy.github.io/skr_rrf_e3_pins.html -
@jay_s_uk I completely missed that this was an SKR board.
