are you loading the mesh file in your homeall.g?

I dont have touch The homeall.g
Do i need to change something in homeall.g ?

What firmware version are you using?
What do you have in your slicer start and end gcode?
-
running a G28 will clear your bed mesh.
if you want to use the stored heightmap you will need to run G29 S1 after every G28 -
Does g28 clear the mesh? I didn't think it does. But I'm really not sure come to think of it.

You are right it does not. i just checked.
I must have confused it with marlin where it does. -
@lui2004
nevertheless you need a G29 S1 somewhere to load the mesh after powering up your printer. -
Hi
The heightmap ist Stored i can open it in my sd-card.
Do i need do load G29 S1 every Print i started?if yes i dont have do it
-
@lui2004
no but it is a good idea to do so.
it is just a command and does not take up time. -
Ok i will give it a try
Or i insert the gcode in my bed.g to load automatic
-
Or put it in your Slicer 'Start GCode', easiest way I find.
-
I have G29 S1 at the end of my config.g that way it's loaded every time on startup.
-
so the first print after mesh works perfectly but when i start the second the nozzle is to high
i have try to send beofor i start the second print G29 S1 but always the nozzle to high

-
you do home before each print?
-
yes in my slicer is this starting code
G28 ; home all axes
-
@lui2004 what is at the end of your files that the slicer is putting in there?
-
I have only G28 i my starting code nothing else
-
do check with m122 that mesh bed leveling is still active.
-
@veti said in problem with the Mesh?second print start in the air:
m122
seems active
