Move over X,Y,Z

Hello everyone,

I have a question of understanding.

I have checked all axes on my AR4 and everything is running as it should.

Now I'm a bit confused about driving over X, Y and Z.

If I now let J5 point down and then let it move on the Y-axis, it moves in the respective direction, but turns J4. Thus, the gripped object does not remain horizontal to the desk.

Is it correct?

This also happens when driving on the X-axis.
