I finally got my new laser engraver last week. Its a Redsail M900. Happy with it so far but I'm having an issue when I'm engraving into wood. The pine that I'm engraving has raised ridges where the grain of the wood is.
I presume the grain is harder than the rest of the wood so the laser doesn't burn as deep.
Does anybody know how I might get around this problem with some changes to settings or maybe the wood type.
Any help would be appreciated.
Thanks
