Weird Linear Operation of ABB IRB120 by Linear Motion RAPID flexpendant.

I use X, Y, Z Linear Motion, but only x-axis is right when using X linear Motion. Y, Z not go straight line but in a weird trajectory…

Despite the flex pandant is going on X,Y,Z linear, the real robot cannot move in straight line. It is so weird.

Can some one help me ?

Start by checking the calibration offsets, then verify the correct robot type has been installed, including the type variant, if applicable.

I have fixed the problem by re-calibration. Thanku!
