Beginner needs advice on Z-axis moving. if move 1.0 shouldnt it move 1mm on axis?

[Warmaster]

been struggling with hictop prusa i3 copy from china.
Z-axis is giving me a headache.

Example first.
If i move X or Y axis from repetier 1.0 the move 1.0mm but if i move Z 1.0 it moves 6.3mm

On my config the microstep settings are
80,80,1638,94....

Am I so lost or dont undertand something about the movements? shouldnt all axes move in millimeters?
if I set 10 from repetier then it moves 10mm on axis?

What might be wrong or am I wrong about moving?
I have MPX3 board on my hictop. They use a4982slpt(just in front of motor connector) so I guess they are 1/16th step. allthought im not certain.

Please help and tell me what am I doing wrong or have I understood something wrong.
