Z Axis only going down

[Viroth]

HI,

I got a problem where my Z axis is only going down, When Move axis on the menu, from 0 to say +10, it will move down 10mm, when I change from +10 back to 0, this again moves down on the z axis. Anyone have any ideas?

what's your printer type? have you homed your printer before you control it? if not it might behave like this.
And seems your motor direction is wrong, check out this link:
