Fusion 360 origin vs Gcode origin dont match ( exact tooldiamater more on X and Y) for GRBL Postprocesor

[Anonymous]

Hey guys, 

Im having torubles with setting WPOS on mymachine.

When i set the origin on Fusion at a corner ( left-botton corner viewing the LCD display of my computer (xy plane)) then i post the milling operation, the origin of my Gcode is offset by exact the tool DIAMETER (positive).

When i open the BCNC, that offset shows up and when i start the milling proces it messes all around eith my model. I have to edit the gcode from BCNC doing this:

"G0 X-(tool diameter) Y-(tool diameter) " - at the begening of the gcode-

Whats happening?

When i set the origin on Fusion at the exact center of the model, the gcode origin match correctly. the problem is when i post the gcode with a different origin than the center of the model.
