The part should have the curved cut centered on the piece but when ran thru Sheetcam it shifts the cut toward the left (toward 0).

I try the same dxf file with LazyCam and I get a nicely centered curved cut (but I have issues with the .375" inner holes being .5" with LazyCam)

What am I doig wrong? I was so excited that the pieces were coming out with the length and width correct and the notches were fine too. I never noticed the end was wrong until I cut out 2, so I checked the drawing and re-ran it thru SheetCam with the same results.

I took a look at the drawing and I only would change one thing. The outside of the part I would make as one poly line. I'm still learning this CNC stuff and its new to me. Seems like if its one poly line it cuts more accurate then if its in line segments. Just my two cents worth and someone else can give better advice. Its just something you can try.

Hope you have a great day.

Makes no difference at all in regards to accuracy. Some CAM programs may prefer polylines, some may prefer seperate segments. Use whatever works best with your chosen CAM program.
