John, thank you so much for trying that. Now that I slow down the preview in Estlcam I can see the stutter in the preview also. Sorry I wasted your time to test that out. I will email Christian about the Estlcam issue. Before diving in to find the issue I noticed this issue when it would do a miss cut early on, but then eventually get back on path.
Ryan, I will print out a new C-XY and measure/compare it to the STL file.
Thank you for all of the help!
