square outside corners

V-bit will do it.

Edit: Never mind, just now looked at the image. You can do that with a straight bit but you'll lose the slope.

That was with a v-bit and v-carve tool path in Aspire. It gives me the square (inside corners) but not the outside. Tried different size/angle vbits with different spacing between the two vectors. Same result each time.

Sorry, need the slope on both inside and outside.

I have never used this approach but in vcarve and I would presume that aspire has what is call a gadget call a dog bone I t is used for square corners look it up on on vectric

Not exactly but as that is probably the nicest MDF raised panel door I have seen. Would you mind sharing the particulars (bits, toolpaths) The one Im working on wasnt my design and truthfully I hated it even before I ran into trouble with it and now I hate it even more. I did manage to get it to work finally by doing a combination of v-carve for the outer pass and then 4 profile passes for the inner with a pocket tool path to clean out in-between the V and the profile.

These are made on a Ritter. Check for videos online

Hey Mike - your attachments go to a Hitachi Manuals subforum.

You need to add a couple of vectors and a couple of toolpaths. See my attachments

Thanks Mike.

Mike's idea should work, making 2 more rectangles to further define the profiles.

another option; on the profile toolpath, go down to profile options "ramps/leads/order/start at/corner", select corner. in that window you can select square inside corners and square outside corners for that profile.

Using this way you will still need to create the 2 vectors for the pocket toolpath to clear the waste material between the chamfers(profile toolpath). You can do away with the V-Carve toolpath.

Yes, however without the V-carve tool path the inside corner still has a small projection when using even a .25 flat bottom clearance bit. Its not bad and a sharp chisel will clean it right off I'm sure. Having a v-carve tool path cleans out that little bit but takes more machine time so its 6 of one half dozen scenario. Thanks again for everyone's input I had given myself a pretty good headache Friday trying to get what I wanted.

Rather than a rectangle I think you have to do 4 independent lines.

rectangle works, if you select square corners but 4 independent lines works too. I did both but the rectangle is faster to draw.

I just ran a test in V Carve and if you do a V carve and not a pocket it will square the corners inside and outside.

Can you post a screen shot of the tool path. When I did a V-carve tool path it would give me square inside and rounded outside corners no matter what.
