I have no idea if the roughing has been figured out in the pass but
I'm glad I was able to find it for my upcoming project with inverted dovetails joints.
I haven't tested it because my CW doesn't work so if someone is willing to give it a try
you'll obviously get a free pattern from
www.cnccraze.com.
This is for a .5" pattern with a 300 height. Not sure if this technique can
be used for all projects and patterns. Once you see the method used, you
should be able to know whether you can use it or not.
Two MPC's are used.
Change your board size if you need to for each MPC.
Make sure carvings are exactly at the same place on both jobs.
Load the two MPC's on your card.
Do the "first pass" which is basically like a pocket hole done with
the 1/8" cutting bit (can be done as a draft) and once it's done, leave the board in place and load the "second pass".
Reload your board using the "second pass".
This could be used for patterns deeper than .25".
I assume by doing this pass, it should extend the life of your 1/16" bit.
Here are the 2 files.
