I roughed out the bulk of the matrial with a 6mm ball cutter to the finished depth using the offset stratergy wit a 50% stepover then finised off with a circular stratergy with a 10% stepover. The material is hard wood and it is for a fibre glass mould.
As you can see from the GCode snippet the z axis variation gives the bumps.
