Check everything related to axis backlash ...everything !
Motor couplings, pulley set-screws, ball/lead screw mountings and bearings, belt tension/slippage ..... any and everything you can think of.
Test the backlash with an indicator.
If it worked OK before, something has changed, come loose or worn out.
Just for starters,
Russ

.. I should've asked ..What type of machine is it ?
.Is it a mill ? router? plasma ? or ......
Type of axis actuation ? ? ?
A pic or 2 might help also.
The more info ... the better.
