z probe sensibility and mesh calibration with G29
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 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?

@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 .
