Hi there. I'm new here and still learning so apologies if this is a dumb ask but does anyone have any ideas how to cut a shape out of another shape? I've tried so many times and the bit I cut out just won't fit back into the bit it's been cut from
I've tried with hearts, stars, butterflies and have failed each time.
Many thanks in advance, Ruth
Does anyone know how to do this?

Re: Does anyone know how to do this?
Hi! How do you mean it doesn't fit? There will always be the tool diameter gap between the two pieces, so if you want to make a tightly fitting pair of objects that fit like a puzzle then you will have to cut them from different parts of the material. Often you would use a single vector to define the shape, then cut the 'inner' piece with a profile toolpath outside the vector, and the outer piece with a profile on the inside of the vector. Allowances let you adjust the clearances to get the fit you want, so it may take a couple of tries as you get accustomed to your machine and the material's properties.

It's what the inlay toolpath is meant for.

The other and easy problem you must over come is what size is the bit you are using. Just because you bought a 0.25" end mill does not mean it is really 0.25" The best and easy way I have found is to lay out a square cut it and measure the cut out. If the cut out is under then your bit is less than 0.25" if the cut out is over sized than your bit is greater than 0.25" you can change the bit size in the tool data base by setting the "Geometry Diameter" for the bit you are using when you created the tool path. This is also a problem with V bits, In the case of a V bit it will be the angle is not what it say it is. I also found the cut square idea works for me , BUT now you must also check that the cut depth is correct and agrees with the cut depth you set in vcarve. If the cut depth is not correct then you are not setting your bit to zero correctly also a newbe problem.

Oh gosh, I hadn't even thought of that. I just took it for what it was! Thanks so much for the help and advice. Off to check the size now....
