    Hard to say, it could be a number of things. If it's not a software setting or your toolpath causing the issue, then you're either loosing steps or have excessive backlash. I'd start by double checking all of your mechinacal fittings and make sure your shaft couplers, bearings mounts, ball nut mounts etc (anything that moves) is nice and tight.
