Z axis going down on printing only

if i click to make my Z-Axis go up it will go up and down same it will go down
when it does its auto-leveling it seems fine

but when its printing it seems to be going down not up on each slice

  • Direction set wrong?

    Up means distance bed/extruder increases. Some printers move bed others extruder so it is misleading to define it other. So hope you meant this definition.
  • where is this setting
  • In firmware configuration.h

    But question was more if the direction was configured correctly. You said you can move z up/down manually so that works in general.  Generated gcodes normally only move up (my definition) means that if it then goes down that the direction is just configured the wrong way, also I do not know why homing and z probing then would work as you expect except if you also added errors to cover the direction error. That is why I told you how increasing z should move so you can compare.
