Hey guys, so I’ve been using my X-Carve daily since I got it about a month ago and it’s been going very smoothly after overcoming a few challenges early on.
Today, I’ve run into an issue that I can’t seem to get an understanding of, and hoping others with more experience can provide some pointers.
I’m carving a sign, using a 1/8 straight bit on 3/4" Birch, carving at 120 in/min. I’ve carved this same exact sign several times already and have had no issue, with the same settings. About 25% into the rough pass I noticed that my bit broke inside the collet I removed it and inspected the collet and it seemed fine. I assumed it was a fluke of some sort and I replaced it with another, a brand new bit. A little bit into the carve, the same thing happened.
Both bits shattered inside the collet at the exact same location.
I put in the 3rd bit, and what I notice is that in certain areas, it gets bumpy. I’ve turned the feed rate down to a very low rate of 20 in/minute and so far it hasn’t broken, but it also doesn’t look right. When it’s carving the wood in certain areas it looks bumpy, while in other areas it looks smooth. I’ll attach a picture of the carve below, showing what I’m talking about.
Could it be just stubborn wood?
