XYZ calibration test 100x100mm

test your step/mn
1 : print this model
2 : check the distance
3 : adjust your step:mn

for exemple if your step /mn for X axis is 160 :
i print STL model and mesure X axis : the lenght of my print for X axis is 100.62mm
normaly the lenght for X axis is 100mm

calcul : (160 / 100.62) x 100 = 159.01
i can change my step/mn 160 to 159.01
Make the same for Y and Z axis
