Mesh Leveling ? Auto Bed compensation?
-
Hello.
My printer has four lead screws for Z axis and a BL touch.
So it's easily possible to level the bed automatically.
Today when I was printing I noticed that the Z motors are moving while printing each layer.
It seems that the Z motors are adjusting the level according to BED's warp.
I actually don't understand the difference between Auto bed compensation and mesh grid compensation. I tried to find the manual for Auto bed compensation and mesh grid compensation, but I couldn't.
Can anybody let me know where I can find the manual for these? -
The bed compensation aligns your print bed evenly.
And mesh compensation compensates for unevenness in the print bed during printing so the z axis will move when you print

@siam Oh, That's great!
But one thing I wonder is
OK, with mesh compensation, the machine compensates, but until the top ?
eg, If I print a cube with warped bed, the top of the cube will be also warped then ? -
@hiroaki ähm no let's say when your bed is on the right side 0.5mm higher as your left side. When you now print a cube then the Mesh will compensate this so that you will get an unwarped cube at the end

@hiroaki by default, mesh compensation will apply up the full height of the object, but you can set up Mesh Compensation Taper (M376) so the amount of compensation applied reduces as you go up the part. You can read more about it here:

@engikeneer Thank you so much. I will check the guide!!!
