Gotcha was not my intent. I intended to share and educate. In hindsight, I could have revealed that was what I was doing.

You failed at this intend, starting with the chosen title...

That is what the friend called me. He said I should open a consulting service.

Either way, after 10 prints of the same item, he has achieved adhesion with ABS on a smooth PEI by raising the hotend (Z).

I am sure each of you offer perfect written communication each day. It is easy to post something that is obvious to you but no so much for others.

I have helped many folks get their printer working. Going Lower is a widespread mistake. People keep going lower and lower until they scratch the bed.

You could have simply shared the information you wanted to share; or written a quiz that says it’s a quiz. I don't appreciate the “gotcha” approach here.

Actually, he is incorrect. I will give you the answer. It is subtle. If you look at the image, there is a waviness to the surface. The print is ABS. It is being squished too much. He raised the Z by a smidge, and the printer now printed perfect x 5 prints.

I posted this so folks could have an example. I knew the answer when I posted it. The user that asked for help actually tried to lower it more, think the same as you did, and it peeled off the plate more.

I think krpreid is correct.

The key is to look at the texture of the surface.

The first layer photo isn't quite focused and lit well enough for me to be sure, but this looks like the “live Z” is set too high, so the filament is not being pressed firmly into the sheet and will not adhere properly. Run the first layer calibration procedure and adjust until the square it prints is a solid sheet of plastic, not separate lines. If the first layer starts showing large ripples that build up as the infill is printed, then you've gone too far down.
