I have a bltouch clone which work fine on glass bed. After switching to textured PEI sheet, it’s variance trippled to 0.1mm, which make my bed mesh all wobbly.

I’m I suppose to remove the steel plate when making the bed mesh? Do you home Z with a probe with this setup?

The weirdest thing is, despite all this all my prints adhere completely fine. I guess PEI is just that good.

    Sure does work… But I have babystepping on (Marlin), and adjusted babystepping by coding in a 30x30x5 block with 8 skirt loops 6mm away. The babystepping in this case is to adjust the Z offset, which it does so live.

    I was able to get it tuned in so that all prints just apply beautifully.
