Watercutter activating early

Hi,
I have recently upgraded a watercutter to linuxcnc and as such need a CAM software, i found sheetcam and its been gret, things like slowing on corners and similar is easy to implement and use and im a big fan. However i have one issue, when making a gcode file the first operation/cut activates the tool before moving to the required location to start the job, is there any way to fix this or will i have to edit every gcode file i make?
Thanks in advanced
