Figured it out.... I was getting the sawtooth tab action when my connection tolerance was to large, 0.125" in my case, depth per pass on that tool was set for 0.125", might be a correlation there.
LC version 3.00.2 here too.
That comment in one of the videos about having a look at the connection tolerance if you get strange postings had always been on my mind, I thought I'd already explored that avenue, oh well.
Until next time,
Curtis
