Hello, 

I have two identical Ender 3 V2. Both are running same setup, same settings and same firmware. 
I checked all screws and angles meticulously. First layer ist just perfect and im also running BLTouch. 

If I printing XYZ 20mm Calibration Cube with 2mm layer height, one printer makes it perfect and the other one come with only 19.20 mm on Z height. 
You can see on some layers, that they are too close to each other...

Any idea what it could be?

Solution is to Set Z Axis Steps-per-unit: 
Check current values ->

Send: M92
Recv: echo: M92 X80.00 Y80.00 Z400.00 E93.00

Calculate new Value -> 
New M92 value = Desired movement / Actual movement * Current M92 value
New M92 value = 20.0 / 19.2 * 400 = 416,66666

Set new Value -> 
m92 z417
M500

 

PS: Also feasible via the display of the printer
