Post procesor for Mach1

Which Post processor do I need to choose in AlphaCAM to run Mach1.

I have tried Alfa Standard and fanuc 6mb no rems

I always get the path in the path tab, but Mach1 don't run.

I'm getting some of these warnings:
Error in File at Sequence Number : 11
File LineNumber : 70
Cannot do g1 with zero feed rate
N70 G1 X1.253 B0. F0

But I'm setting the cutting speed.
