Bed leveling : Z axis not moving while printing

[DzzD]

Hello,

I've installed 3D touch on my A20M, levelling works fine but when printing, the Z axis is not moving to compensate, what do I miss ?

Hi, If you mean that the z axis is not compensated,
You can refer to this for calibration: viewtopic.php?f=27&t=18371
The specific operation video can refer to this: https://www.youtube.com/watch?v=_RtsZDbR2po

Yes that's what I mean, bed leveling works fine and output grid value. but it does not compensate while printing.

I am stil not able to use bed leveling, any idea ? setting in Marlin 2.0 ?

here is the output of M420 V :

Code: Select all

Send: M420 V
Recv: Bilinear Leveling Grid:
Recv:       0      1      2      3
Recv:  0 +0.280 +0.221 +0.162 -0.080
Recv:  1 +0.060 -0.068 +0.056 -0.028
Recv:  2 +0.036 -0.036 -0.038 +0.033
Recv:  3 -0.223 -0.157 -0.038 -0.033
Recv: 
Recv: echo:Bed Leveling ON
Recv: echo:Fade Height OFF

Here is the issue I got : https://github.com/MarlinFirmware/Marlin/issues/13512

Hi, Does this happen when you print all models?
Can you provide your specific video?

Yes it happen with all models, even when I add "M420 S1" after "G28" on the starting gcode and I am sure the bed leveling data are ok because when I do a "M420 V" while printing it output the mesh leveling datas, I am really lost on this issue...

Sorry no video but the issue is simple : z axis is not compensated while printing (it is not moving while printing a layer)
