when pressing all axes Homen. Homed he x y u and then pauses for 15 seconds before homed the z axis.

Do not use H2 for this move. H2 is only needed when you are trying to move an axis that has not yet been homed, such as when you want to lift the Z axis slightly before an XY travel move.

G1 H1 X-400 Y-400 U400 F3000

You're also sending another homing move for XYU after homing Z. Is that actually intentional?

For example, your file should probably look like this instead.

the pause before the Z Homen is still there.
i homed x y u to z again so that the extruder is not in the middle of the table

Phaedrux

Is it pausing before it moves to the probe point, or is it pausing before it does the g30 to probe?

Try this one with some messages inserted so we can see what point it's pausing on.

In that case just use a normal G1 move without an H parameter.

then the Y axis was not at zero but +4

@Phaedrux Now the homing runs cleanly.
Thank you for your help.

@Proschi78 said in Homeall.g pauses in front of the Z Home for about 15 seconds:

G1 H1 X-35

Is that a long enough of a move to ensure the X endstop is hit?

Proschi3D

@Phaedrux yes the x and u limit switch is hit.
Unfortunately, because I have little space to install something to clean the nozzles

Phaedrux

What if your farther than 35mm away from the endstop?

Generally it's best practice to have the homing move by at least as long as the length of the axis.

Proschi3D

@Phaedrux I have extended the way thank you
