VCarve G-code export for easel. Feed ramps up fast!

Hi, Just wondering (this may not be the forum) if anyone can help me. When i export the G-Code from Vcarve it seems to go to the right position and all (code exports in imperial only for some reason) but as soon as it plunges and starts cutting the feed starts to really ramp up so i have to quickly stop it. Is there something that should be in the G-Code? How do I convert to metric code from vcarve? Any light on this would be awesome. Thank you.
