Image alignment issue may be stepper motors?

aloha from hawaii…im hoping i can get help with current engraving issue . i have a 60w chinese laser with ruida controller.
the picture with motorcycle is skewed to the left starting at zero scan angle. when i start scan at 180 it skews to the left but in the opposite direction.
the picture with fish is numbered 1 and 1 …2 and 2 etc to indicate where those segments were supposed to end up.
text and vector objects seem to be fine its only photo type images that are affected.
thank you in advance for advice and support

This is worth review:
