I have had my X-Carve 1000mm for almost a month and have made some nice stuff with it. With some of the wood I have tried I get some stringing around the edges (see photo below)
This is Black Walnut; it came from a tree my brother had on the property that he had processed. I am not sure if it was dried properly. I used the recommended settings for walnut, and this is what happened. I have tested some other woods and some work just fine but others do this. I wonder if its just the wood not being dry.
I have made rosettes in quarter sawn spruce guitar tops using straight router bits for years. The grooves always look like that after cutting by hand or cnc. A hobby knife will remove it easily when the blade is sharp. It’s almost like shaving.
