 ## Other points
 
 * It is important that the centre of the part is in the centre of the bed to ensure the CAM settings correctly align
+  * This can be avoided in Fusion if you create an additive setup with the correct origin for your printer, then use that origin for you cam setup. (you do not need to use the gcode created by the additive setup, only use it to set the origin)
 * The part must also be oriented with the same XYZ axis as the CAM'd part
