z axis steps are lower then they should be
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 ->
PS: Also feasible via the display of the printer
