IF you are not familiar with the simulator being able to rotate - just click and hold down on the mouse at the bottom of your graphic in the simulation and pull straight up to the top center of your monitor, move side to side to tilt, etc. You will find that your very faint tool paths MAY appear, especially if you have a very sharp angle like looking at your wood blank at an angle of about 15 to 30 degrees and then move the graphic around again.
I’m having the same problem though and I am still missing one of my tool paths in the upper left corner of my design. I’ll keep working on it.
By the way, I downloaded the suggested Camotics software pkg and found that even more of another Tool Path is missing, however, ti still did not pick up the missing upper left corner item - it is a 0.063 ball mill.
