Pocket (contour) behavior - CNC mode

Hello,
I’m having trouble correctly setting up a pocketing operation, particularly when enabling the contour. The generated toolpath always extends beyond the pocket and performs passes outside of it. How can I ensure that the bit stays strictly within the boundaries of the pocket ?

Here is an example :

Hey there,

It seems that you had the contour option checked for one of your pocket operations. By unchecking it, you can make the path stay in the boundaries.

Is this what you were looking for?

Thx for your answer !

In fact, I use 2 different pocketing operations :

  • the first one removes most of the wood, but fails to go to the exact wanted surface (often it leaves a fraction or even 1 to 2 mms, I assume depending on the step down parameter). This alone is often insufficient.
  • the second one, with the contour option, properly finishes the work

I’m not sure if I can do things another way ?

I think I understand better now. It sounds like you are looking for the trace (clear) operation.

If you set the step down to 0, you can trace along the bottom of the areas you want to clear.

Here’s a screenshot and KMZ of how you can use this operation.
