What is the true repercussion for the object from automatic bed level correction in the 3D-Printing?
I have a simple question. The automatic bed level correction forms the first layer along the unevenness of the bed, ensuring adhesion to the bed. That works fine, but the 1st layer must has unevenness.
And, where does the unevenness that seems to be absorbed or not in the other layers?
Could you please show me the way of? I post some case as follows.

  1. The unevenness is absorbed in the first (few) layers and then remaining layers are flattened.
  2. Or, if I use “raft” in the bottom, the unevenness is absorbed only in the “raft” ?
  3. No. All layers has same uneven from the bottom to the top, followed the unevenness of the head.
  4. Or, are there any other methods?

I have actually crashed my nozzle into the print bed once when I tried out the M420 fade out. I really hope that they disable that function in the future to prevent such mistakes or just make it work. Fortunately, the replacement print sheet was delivered within one week :slight_smile:

Thank you brent113 & dstarke! The current answer is 3,that’s in the firmware; all layers has same uneven.
I have to jack up my searching skill, sorry. But, I’m grad to know there is another person in community have a same question. Thanks again. :smiley:

Ha, nah
I just remembered posting that. Struggled a bit to find my own post
