one thing I see may be that you are already calling the cutter to .912" in the program. If you have too much height set in preperation it may be X axis stroke that is causing the alarm. Do you see which axis the stroke alarm is? I bleiev L-20 should specify.

If you do not account for the live tool shift and add .590 to your MC data length then you are probably alarming with Z axis stroke. (part length + cutoff width + facing amount + shift amount = machining length) easy to miss sometimes.

I agree with carms, the .912 is probably what is doing it. I only rapid out just enough to clear the tool, never more than .100" above the material. You can rapid higher, just make sure you have enough room on the tool prep page.
