sounds like it might similar to my issues, where the up down movement on the y rails is enough to cause a variance in the first layer height of +0.2 mm in some parts of the build surface. Below is the post where folks helped me figure it out and confirm it. Plus the post of the test i was doing that made me realize i have issues.
Ok, at risk of making myself sound stupid.
If i have model that is .2mm high on the z and my initial layer height is .2mm why does:
a) the skirt print at .2mm high
b) the model print at .4mm high
doing this the model only has perimeters, solid infill and external perimeter
I am using prusa
ironing is off which adds a layer in the slicer)
I am using a true micrometer to measure (not calipers)
is this one of those conventions like where 2x4 wood is not actually 2x4 inches?
am i doing some…
Now i have solved my sloping bed issues, I continue to try and get the first layer to be the same across the entire build plate. the image below shows where I perceive I am failing. this is the print held up to a screen to act as a light box.

It is printed on a metallic PEI coated plate i purchased ages ago but have not used until today. This gives much better results than the black stock surfa…
