I have read the topic “Can the Shapeoko cut 45 degree mitre joints” which was helpful but didn’t really go into the Carbide Create Setup. If this is obvious, sorry I had to ask…
My question is how do you set this up in Carbide Create?
Say I have 1/2 inch stock. I want to cut the left and right side of the square for mitres?
When I use V Carve and change the bit to the 301 (90 deg) I get an empty tool path.
If I use a rectangle it doesn’t give me a straight cut. It’s pretty but no a mitre…
If I use Contour and choose V Carve for the bit It does look like I can set No Offset and theoretically this would carve the mitre? If so then what is the difference between contour and v carve?
Any suggestions on cutting mitre joints on a shapeoko XL esp around setup in the Carbide Create would be very helpful.
I understand this is Fusion 360 vs. Carbide Create, but just wanted to get on the same page. You want to cut a sort of “fold up” box with 90deg V? I admit I’ve barely used CC, so I’m not sure how to do this. It sounds like you just want to do the left right edges (vs. for this box example, I was making panels with 3 mitered sides, as the bottom was also mitered to insert).
I just spent ~2min putzing in CC and don’t see how to use V carve or contour to just select single edges vs. the whole rectangle, nor how to draw only lines.
Anyway, sorry I can’t help directly, but I thought a concrete image of what you’re after might help get folks thinking and trigger a suggestion for you.
My thought was if your real piece is, say, 3x5in (left/right in the 5in direction), you could make your rectangle something like 5x5. In this way, it would make complete vertical passes on your l/r sides, but be completely clear of your top/bottom when it continues around the rectangle.
Maybe that would work? I concur that setting stock bottom is what you want, zeroing the bit to right at your wasteboard surface. I found this method awesome but tricky. Seems like just a little off and my bottom didn’t want to quite fit right. I found radiusing the corners just a hair with sandpaper after assembly helped hide my boo-boos, and filling one “learning pain” corner with glue/sawdust also worked great
Note that you will either need to use a wider endmill or do this in two stages, using an advanced V carving for the first pass down to a depth which will allow a normal V carving:
If I understand, the 90 degree VCarve bit is 1/4 x 1/4 so on a half inch board It would not be a miter, more of a straight route with a quarter inch v at the end…
I get that the Advanced VCarve can handle two sets of cuts? But I am not able to visualize how that helps.
What I ended up doing was create the first rectangle to go all the way through to give me the 90 degree angle at the end, then did a second rectangle a quarter inch away and just 1/4 inch deep, finishing the Miter at the top of the board. Works fairly well.
I would like to understand the Advanced VCarve better. The information in the manual was pretty general.
