How do you guys program the lead-in when using Fusion 360 for Cam so that the tool doesn't get dragged through the side of the part at the start of a job?

I've been having problems with this lately. The simulation in CAM looks good and reports no collisions. I zero my machine and touch-off in linuxCNC but, when I click "run program" it drives the tool into the stock.

It completely ignores my lead-in setting and all the off-sets etc.

It happens in all toolpaths I've tried, but how do you guys avoid this in 2D pocket clearing, for example?

Every video tutorial I've watched skips over this bit like it doesn't matter but I'm clearly not understanding something key...
