By just looking at the file in CAMotics I see several issues.
They could be related to how and where you set the surface height of the workpiece.
This post has some infos: Fusion 360 confusion
The letters are higher then the heart and the map. The X has some strange ‘stepdown’ only on the upper right angle. The E has a ‘helix hole?’ and only 2 complete cut paths, the heart has that ‘hole’ also.
I guess you need to reconfigure the heights like in the post I linked.
