post a picture of your mesh grid

You can likely improve the results of your probing by reducing the probe speed and increasing the trigger sensitivity.

Try changing M558 F120 and G31 P25 and redoing your mesh compensation.

You can also try increasing the detail of your grid by reducing M557 S40 to S20.

Looking at the picture, at one side the skirt doesn't go around the printed object, as if the head cannot go all the way. Are the x/y dimension in your config.g and slicer correct?

For example, shouldn't these be 0:220 for x,y?

M208 X0:170 Y0:200 Z0:300

Try to clean the bed and turn off the fan during first layer

TiToMoskito

I cleaned my bed alcohol, so there is no fat or fingerprints on it.

Can someone tell me how to make my mesh grid bigger?
When i change the grid to
M557 X0:200 Y0:200 S40
it will probe outside the bed, and it doesnt start really from zero it always start from the homing position.

By the way, the homing position shouldn't it be on the center of the bed ?
homing_pos

My bed dimensions are: X: 220 Y: 220 (prev. on klipper i had on y 235)

Here is my heightmap: heightmap.csv

I put my z on zero and made a manual paper bed leveling (sorry i dont how to call it, i hope you understand what i mean)

Veti

what material are you printing and at what temperature?

TiToMoskito

Im printing PLA with 200°C and 60°C bed temp

Veti

can you try the values for the thermistor from this and see if it makes a difference?

Can you post your homing files?

TiToMoskito

@Veti this is not a temp issue, i think its more a calibration failure on my site.

@Phaedrux What kind of homing files do you need?

nevertheless your thermistors settings are not correct.

all of them? Homeall, homez, homex, homey. bed.g as well if you use G32 at all.

TiToMoskito

@Phaedrux i hope its everything
homez.g homey.g homex.g homedelta.g homeall.g bed.g

Phaedrux

From your homeall.

G91                     ; relative positioning
G1 H2 Z2 F6000          ; lift Z relative to current position
G1 H1 X-235 Y-230 F3000 ; 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-235 Y-230 F360  ; move slowly to X and Y axis endstops once more (second pass)
G90                     ; absolute positioning
G1 H2 X51 Y22 F6000     ; go to first bed probe point and home Z
G30                     ; home Z by probing the bed

The position of the bed probing for the Z axis is set as X51 Y22. You can change that as needed to position to probe at the center of the bed.

TiToMoskito

Thanks, i changed it to 117 to the center of the bed.

My mesh grid is set on X to max 180, why does it exceed?
M557 X5:180 Y5:215 S10

And why does it start at X: 49.0 Y:22.0 and not from 5 ?

Are you getting messages in the console saying points unreachable?

The grid specifies the area of the bed you want probed. But the probe has an offset from the nozzle and it's possible that it cannot reach all points.
