Hi folks,
I'm cutting my first hardwood on my cnc, occasionally I get a tiny bit of tear out whilst profile cutting and I'm just wondering would switching from conventional to climb be a good idea?
Thanks in advance,
Mark.

Yes, usually climb cutting gives better surfaces on wood, when using a CNC. For best results, try doing a rough cut first to remove most of the material, and shave off the remaining few hundredths of an inch with a climb cut.

From my experience, conventional cutting is almost always better than climb cutting.

However, when you're profile cutting something, there must be wood on both sides of the bit. If not, you'll almost certainly get some tearout, regardless of cut direction.
But if you must do this, climb would work a little better. I'd leave about .02 to trim off with a conventional cut.

If you can leave material on the outside of the bit, you should almost never get any tearout, and will get much cleaner cuts with conventional cutting.

those two answers contradict each other, which is the problem I've been struggling with everywhere online.
Ger, I think that explains it, on a certain part there isn't any wood on one side.
