[Print height is smaller than expected]

I have this : ";MAXZ:20"

 

I think it's normal isn't it?

[Print height is smaller than expected]

 

 

Hey guyz !

 

Prints on my Ender 3 Pro are smaller in height (Z axis) than expected. X and Y size however are accurate.

 

I printed some calibration cubes to be sure.

Difference is about 4%, the height is around 19.15mm instead of 20mm.

 

I use Cura to slice STL files. I can increase height percentage at around 104% on Cura but for me it's only a workaround and I would prefer a more durable solution than increasing height each time I slice a file.

 

I double checked:

• E step : perfectly fine
• Z step : same
• Z binding : followed a tutorial on youtube, shouldn't be this, but I can't be sure
• Z axis bar is perfectly flat, no curve or whatever

 

What should I investigate on in order to solve this?
