Defining G29 Grid plane

Puppet172

I have the Grid defined with M557 in config but it still doesnt allow me to run the mesh bed leveling. Is there anything else i need to do?
0_1529804473162_config (1).g

If you try sending that M557 command from the GCode Console, you will find that it has too many grid points, and you will get a suggestion for the value you should increase the spacing to.

What is the max amount of Grid points allowed? Is there a way to make more of them?
Also when i try to change the trigger height for my z probe it doesnt really seem to be changing it. Why would this be occuring?

the maximum us 441 e.g. 21 x 21.

Possibilities include;

You have a config-override.g. file on your system containing a G31 command that is overriding the one in config.g;
You haven't put the G31 line after the M558 command in config.g.

The G31 command it after the M558 command. So are there any other possibilities of why it wouldn't be changing?
Also i don't have a override file so that can't be it
