Changing retraction distance between toolpaths

[PeterL]

My Shark HD510 is great, but I'm a little confused about how to increase the retraction distance when it moves from the end of one toolpath to the beginning of the next. Twice I have grazed hold down clamps. I have increased the retraction distance within a toolpath in the Vectric Vcarve software, but I often combine toolpaths that use the same bit into one file, and when the tool completes one toolpath and moves to the start of the next toolpath is when the grazing of the clamp happens. Do I change this retraction distance within the Vectric software (and where?) or do I change a setting in the CNC settings? Thanks!
