@Veti now the speed work good thanks but ihave Another problem is it never starts from point X0 it always moves a bit to the side and starts doing bed calibration how ifix it ,You spot something wrong in my
config settings

M557 X0:235 Y20:225 S30 ; define mesh grid

this just says there is a spacing of 30 between the points.

235/30 is not an even number, so it does not fit perfectly.

also you have an offset
G31 P500 X38.2 Y0 Z1.08 ; set Z probe trigger value, offset and trigger height

but if there are no warnings during the probing you are fine.

ihave dde direct drive kit this is th right X Y OFFSET ,
but iget this error
Warning: Skipping grid point (0.0, 160.0) because Z probe cannot reach it
Warning: Skipping grid point (0.0, 200.0) because Z probe cannot reach it

M557 X0:235 Y20:225 S30 ; define mesh grid

you need to limit your grid taking into account the probe offset

M557 X40:245 Y20:225 S30 ; define mesh grid

@Veti this is my problem ido home all
After it g29 and its not start from x0 it dont go all to the end stop
I upload to you tube https://youtu.be/7FL0kCXGIHM

@Roei3d

nice the new metal kit for the ender.

again it does not need to go to the endstop for probing.

@Veti thnks its blv ender 3
itray this M557 X40:245 Y20:225 S30 and it goo out of the bed

Veti

@Roei3d

ok change to this
M208 X235 Y210 Z240 S0 ; set axis maxima

M557 X40:235 Y20:225 S30 ; define mesh grid

ender 3 is max 235. why did you define 245?

Roei3d

@Veti hi clean the nozzle with a brush I put aside on x245
if ido M557 X40:220 Y20:225 S30
no its work good no error its ok ?
