That's totally what I'm getting! I'm using Kapton tape.

Seems like Jim's demonstration is pretty conclusive that the problem is the z-height.
I don't remember if anyone mentioned the different ways of leveling/z-height adjustment in this thread. There's a couple of methods outlined in the Tips thread here:

I'm not very adept mechanically and would have a hard time if I had to do it the makergear way. The method using S3D works wonders for me though. It's about a minute or two before each print and it's spot on every time.

I decided to track down the M2 bed leveling video I'd heard about and watch it for the first time. It is here: https://www.youtube.com/watch?v=R53wWwktH0s
That's exactly what I do! With a clean glass bed, it is very easy to see variations in the nozzle height as you move it around. Very fast and easy to get the bed level to within the flatness of the glass. I find it falls off for me around the edges. If you have your bed covered with a non-reflective material or it is gunked up, it may be easier to use Toby's S3D wizard way.

Have you checked the actual diameter of your nozzle? I had the end of mine "blow out" and end up being about 1.5 mm instead of 0.35 and it did a bunch of crazy things. I spent hours and hours messing with settings and filaments.
Also, check the printed plastic bracket that holds your extruder to the x axis guide rail. Mine developed some cracks and the additional motion due to the loss of stiffness caused some odd things, especially on the first layer.
My machine ran flawlessly for about a year with zero intervention, then I had both of these problems occur nearly simultaneously. My heated bed thermistor also failed and my x-axis belt needed tightened.
