Ok a bit of background first. I was thrown to the wolves a few months ago in our little acrylics shop and made head cnc operator. I have a strong background in machine maintenance but have no formal training with this machine. I've been doing all the machine maintenance since starting about 6 months ago and its in really good shape. What I am having issue with is really bad scalloping..I guess thats what you'd call it..when I cut holes or make a radius. If the radius or hole is large then its not too bad but at say .5" and up it gets really choppy. My bits are sharp and our material supplier has taught me much about chip load so Im fairly sure I have the speeds dialed in. I really need some advice on what to look for as out quality is going to hell rapidly and I need to get it under control. If you need any other info let me know and I'll do my best..oh and if this is in the wrong place please let me know where it goes and I'll put it there.
Thanks in advance,
Fred
