    Strange Circles

    I was hoping someone could tell me whats going on here. Sometimes when I have a dxf file and load it onto my cnc system I get strange circles that appear in the part file that was converted from dxf. Its strange because when I look at the dxf file there is no circles in it and I dont know where they are comming from. I appreciate any pointers that someone could give ...thanks!

    Your IJ mode may be set incorrectly .

    I get that from time to time even in IJ mode, so I use this program to check out the g-code 1st.

    Just out of curiosity, what program made the DXF file and what CAD / CAM program is showing these circles?

    I have seen these referred to as 'crop circles' elsewhere and also here on CNCZone. They are usually an artifact of a arc segment being incorrrectly generated.
