A guy at a trade show in Cleveland told me to always run the first part of a new program with the spindle off.
He said it saved his shop from a $12,000 crash on a 5-axis job six months ago, and now I do it every single time, no matter how simple the program looks. Do you have any other cheap insurance steps like that?

That's solid advice. What was the specific failure mode on his five-axis job, a tool length miscalculation or a work offset issue?

Sounds like overkill for most jobs. I dry run everything in the air anyway, with the spindle on but way above the part. That shows the path just fine. For a simple 2D contour, running with the spindle off is just wasting time. The real insurance is double checking your tool and work offsets before you even hit cycle start.
