Hi, Giordano
Your F speeds are set to F300, Have you try-ed slowing it down.
When you setup Mach3 your Max Velocity and acceleration settings are based on F100, I think, I May be wrong about that ?.
Is your Mach Job finishing faster than the other. ?
All the holes seem to be in the center on Pre-cut view. ?
