Need help with MPC

[jpaluck]

Need to some help to figure this out. I have attached the mpc and and would attach the ptn but it's too lage to upload. This is a pattern for a leg of a bench I am carving. I set this up to have the cutting bit cut out the peice. The project is 3/4 deep and the board is 3/4. The only thing that should be carved is the chip carving peices in the leg. When I set this up the bottom of the mpc show a small cut out on the botton around the outline of the pattern and the bottom of the leg . The top is fine. What I am getting at is I want the cutting bit to cut the pattern out but when I carved this the carving bit carved down about 1/4 of an inch on the bottom half as seen in the mpc show I end up with a jagged edge on that side. Is there a way so only the cutting bit cuts the outline and the carving bit doesnt touch it? I outlined the pattern and had a cut path around it.
If you remove the cut path and outline you can see what I mean.

Hope I explained this right

Thanks for your help

I would try to make a mask around the raster pattern and set to 0 depth.

I noticed that your raster is a few thousands low i would raise it a tad.

some conected lines with a carved region and set it to 0..

Thanks LG it was driving me nuts

How do you raise it higher than 999?

brought in with the stl importer at .75..was modelled at .75 should I raise the model a hair?

[liquidguitars]

yea needs to go up a tad.. you coud try it in the model or the pattern editor.

and jiggly? i would go around it with lines and arcs then delete the cut path.
will save on sanding it smooth.
