Cheers fella, will check that out. I'm doing something wrong for sure! We never stop learning I guess.

The chamfers are also not coming out right, supposed to be just a 0.5mm edge break. I think its because I add a chamfer in the model, and then use chamfer option in the CAM but you end up selecting one of the edges of the 45 degree feature, rather than the now non existent 90 degree corner. That probably makes no sense at all!
