Make sure all the axes dovetails and lead screws are well lubricated. One or more of the axes may be stalling slightly du to that lack of lubrication

The micromill can usually cut quite accurately for a relatively cheap CNC...but you must ensure there is minimum backlash on the screw nuts.
There is some good information here:
