Hi,
When printing the test cube 20x20x20 mm
When i measure the block, top middle and bottom and take average i get:
Z: 19.98mm
X: 19.5mm
Y: 19.5mm
How can i recalibrate X & Y to be more precise?
Is it in Marlin firmware settings?

how to calculate?
((134.74/195)*200) = 138.20
Or is it
((134.74/200)*195) = 131.37
What is correct?
Thx
