You'll have less problems if you convert all arc/mvc moves (MoveC instructions in RoboDK) to small linear moves by changing these settings:

1. In RoboDK, selectTools-Options-Program
   
2. SetMinimum arc sizeto 1 mm
   
3. SetMaximum arc sizeto 0.5 mm
   
4. SetMinimum step sizeto 0.5 mm: this option will make sure you don't export points closer than 0.5 mm so rounding has some effect. You'll probably also generate more compact programs. You can increase this value even more to have smoother movements, however, you may loose accuracy.
