Unwanted circles in Mach 3

[bonmotwang]

I am trying the bowl sample in cut3d. Everything is ok except Mach 3 added a few unwanted circles to the tool path. I am still trouble shooting it. Anybody can give me a quick hint? Thanks

I believe it's the IJ Mode setting in the GeneralConfig window. I had a similar problem awhile back. Did you ask this question on ArtSoft's forum?

This happened to me and countless others. Just change the I/J mode in General Config shown in this screenshot.

LOL this happened to me as well! This should be on page 1 of the Mach3 manual!

Yep, it should be in a FAQ list.

I was lucky. I ran the CNC without worrying about the "circles", thought it was just some "reference" lines in MACH 3. So the End mill cut into the wood made a 3 mm deep perfect circle, without hitting the clamping tools!
