Not all of the stock is gone after machining part

[jmackniak]

I am using cnc wood router to mill a small box.  This is actually my first go at using fusion on this machine so there is somewhat of a learning curve.    this is a simple set up,  2x6 piece of wood with 4 different operations and using the same 1/4" end mill for the whole process.  It works! but there is a small strip of would left on the top where i do a .30" contour around the lip.  I cannot seem to get this piece machined. you can see it in the simulation.

the file:  Box 1

Hey, for your first go at using Fusion, you did pretty well!

Here's what I would do:
1) For 2D Contour, I'd only select this edge:

 2) Turn on "Stock Contours" and select this edge:

3) Go to "Passes" tab and turn on "Roughing Passes", setting a value of 3 or 4:

 

 If all this seems like an awful lot of steps, you wouldn't be wrong. You can also just use the 2D Pocket, and select the face of the ledge:

Hi @jmackniak , Great Job for the first try. What you need to do is add a roughing pass to the second 2d contour, I'd recommend making that 2d contour only the outside line and then add back in a new 2d contour of the inner lip that will not need a roughing pass or vice versa. I did have to change the step over to find all the material and .1 maybe too much but it worked.
