That looks really bad. Can you please send the g-code to the e-mail address in the F-Engrave Help Menu so I can take a look at it?

If this is a repeatable problem it would help a lot if you could generate similar g-code and save it with the "Suppress Comments" option unselected in the F-Engrave "General Settings" window. This will save all of the settings in F-Engrave as comments in the g-code file.

It would also be benificial for you to download the latest version of F-Engrave. F-Engrave Download
