z probe sensibility and mesh calibration with G29

[Tinchus]

Hello. Im trying to use a Z probe atached directly to the noozle, it is a piezo sensor. It works really good as a zprobe, but Im funding problem for doing the mesh calibration routin because it is being triggered before the sensing starts. I get this error:

Error: Z probe already triggered before probing move started

I assume this has to be related on the fast movement between probing points since a single Z probe works perfect, so my question is if there is some way to make the mesh calibration routing to have less acceleration and jerk as the normal printing moves has? I dont see any parameter I can feed to G29 to achieve this
Thanks in advance for the help

@tinchus if you want to lower the speed for mesh levelling, you can do one of two things
1- lower the T value in M558. That covers the travel speed between moves
2- if running 3.3, create a file called mesh.g
within it set new acceleration and jerk values
then add G29 S0
then reset your acceleration and jerk values.

mesh.g will be called automatically when G29 is called

@jay_s_uk taht worked! thank you!

@tinchus which did you go with?

@jay_s_uk said in z probe sensibility and mesh calibration with G29:

2- if running 3.3, create a file called mesh.g

3.2.2 also supports mesh.g

@fcwilt very true! its been that long since I used 3.2.2

@jay_s_uk I created the mesh.g file, and modified accel and jer there for mesh calibration the restore the original values to normal after the G29 S0 command .
