underextrusion upon 1'st print test cube.

I had just started a test cube, and this is what i got, i tried live adjusting extrusion multiplier to 200% and almost nothing is being fed into the nozzle, the prime line looks ok, manually trying to extrude fillament seems to work fine, but starting print i get this almost no extrusion thing, using LGX lite with rapido via superslicer and all config is stock expcept for the ratrig profile .. my 1'st layer calib is ok i compensated for Z and even tried pushing it down while live more but nothing comes out of nozzle still
