Level Adjustment for 3D Printing(Elephant foot)

Hi all.
The manual describes the level adjustment as follows.

3.Keep adjusting the height of the nozzle using Up and Down buttons until there is a slight resistance when you
Pull out the calibration card, and it should be wrinkled when you push it forward.

I first used a 0.2mm metal scale to set the distance between the nozzle and the bed to 0.2mm.
From there, I used a calibration card to make the adjustment.
The height at which the card was crumpled was 0.05mm x 6 times down in the position.

This means that the nozzle is now 0.1 mm into the bed.

If you print with the initial layer at 0.2mm, the actual distance between the bed and the nozzle is 0.1mm.
I think it is inevitable that elephant foot are generated.

What do you guys think about calibration?

I bring it back up one 0.05mm setting and set it there. I’ve never done the measurements but intuitively felt what you describe is happening. And I get elephants foot if I don’t bring it back

Let me be a bit more specific. To adjust for backlash, I actually move the head up 3 times, then down 2.
Otherwise you don’t get the right thing.

Thanks for the reply.
I tried it with what you told me and I got elephant feet.
It’s confusing because the condition of the calibration card and the surface of the print bed will also be smooth as I use it.
I tried recalibrating with a new one, but it still occurred.
I’ll try a few more challenges.
