Bed Mesh V-Core 500 tilted (Front right low, back left High 0.77 difference)

Hey,

I am trying to ccorrect my bed mesh on the 500 i have. When doing a z tilt and then the mesh the front right corner is too low and prints dont adhere. Shouldn't the z tilt solve that for me? Am I missing something else? I've added a picture to show my mesh.

Solution

oh, it is creeping? double and triple-check your couplers from the z motor shafts to the lifting screws, make sure the set screws are tight

agreed, doesn't look like the z-tilt took effect which is weird. Can you make is so the color coding goes from the real max and min and not just .1 > -.1 ?

I hope this is what you meant.

Here is my Z-tilt for reference:

[z_tilt]

-7,0

And here is my motor config just to be sure:

After swapping two of my 2209 drivers around I got this mesh

Could it be that my one motor is somewhat faulty and not doing the correct amount of steps or something?`
So far i've tried almost everything. Switching from 3D Touch sensor to clicky, cause I thought the 3D Touch wasn't okay. Lubing all z Rods and now swapping the 2209 BTT Drivers on my board... I'm absolutely at my wits end and so dang frustrated with this printer...

When you z-tilt, what are the results? Like, what gets spat to the console? Should have some tolerance numbers and how much it was moved I believe

The screws where already tight but i cranked them to the limit, now the z tilt works with .o11 point range. Thank you!
I'll test the mesh again and will see what it did.

Okay, so i've done a few prints and meshes now. It seems to have been fixed. I cant believe that the screws werent tight enough... I really had to wrench on them. Now i still have a dip in the Front right corner, but hat seems to be my Bed, because it is consistent over multiple prints.

Thank you again for your input
