Why is the curved groove has incorrect measurement?

One more thing - remember that you're using a round bit - it cannot make a perfectly square hole - if you can figure out how it can, let me know.

This is the same problem I am having, see "Cut Path and Bit Selection". Basically, are you saying you want to cut a Dadoe. As an example, you have a 1/2" thick board and you want it to fit in a slot that would be, let's say, 1/2" wide by 1/4" deep by 4" wide. You can't do that with a carve region and and get a squared off edge, the carve bit is tapered. I have a MPC on that post to see if everyone can carve it and get the same measurements. Take a look and see what you think.

I thought I posted this project the other night on another post about slots but can't find it....

I made a handy "Cheat Sheet" in wood to be a quick reference for project design. If I need a slot to be big enough to let a piece of wood slide into it with a friction fit and can get CLOSE the first time with my cheat sheat...

Sure it is carved in pine and changes size with hiumidity..... Could have made it from PVC Board for a more stable substrate. But this gets me close... I use the slots to size the slot I need and just look at the .mpc I posted for the hole or slot that I picked to get the measurements....

Give it a try... I used the 1/2 bit to make this.... It is NOT a CARVE REGION with raster mode, it is Vector Cut.

Thanks for that cheat sheet, I can see where it will come in handy.

As I said before, a Carve Region is carved with the carving bit, period - you can't assign another bit to do the job.

Not entirely true. You can use 1/8" bit to do carve region by going into "edit" then "board setting" then click on "pattern bits" tab and pick 1/8" bit from the drop down menu. Your entire project will carve with 1/8" bit. Also make sure to pick 1/8" bit when the machine ask for it.

Yes you are correct. Yesterday someone was asking about dados on a project with no other patterns. I wish I would have remembered the pattern bits option then.

Good idea!

Me forgot, too...

I've never changed the bit in the board settings menu - just what effects do you see when using the cutting bit over the carving bit? Does the straight profile help with chip-out? What about carving patterns - I'd assume they wouldn't carve as "smoothly" as with the tapered bit.

Must be a stress issue, or does the machine compensate for that?

Hmm....

I had posted a thread about the Cut Path and Bit Selection. That's where AL had posted that cheat sheet. Thanks again AL. I will try this method also to see how it comes out. Thanks everyone for your contributions. I'm learning.
