HI

i have updated to Marlin 1.1.9 and i tried to print 20mm cube. but the output was x=20mm, y=20mm and z=26mm

in my configuration.h , i have put

#define DEFAULT_AXIS_STEPS_PER_UNIT   { 80, 80, 4000, 94.69 }

my thread rod is 5mm normal screw.

HOw to fix this issue?

here are my configurations:

Configuration.h
Configuration_adv.h

my guess is your using M6 not M5

M5 is 4000 but you say you get 26 when it should be 20

20/26 * 4000 =3076...

M6 should be 3200 steps/mm so it is my guess

Why not just change the steps to an adjusted number to have the Z-height correctly? smiling smiley

Try 3076 steps/mm and see what happens?

If you are changing the steps/mm in the configuration.h make sure you also update the values stored in the eeprom
