Nozzle rubbing on prints

#1
So I have a new gMax 1.5XT+ and I am testing out prints and have come up with an issue I have not seen on my other printer and could use some help! I'll describe below:

I can hear the nozzle rubbing on the surface of the print as it goes along. Usually it means too much plastic is being extruded and I would adjust the extrusion multiplier downward to adjust. If I do this the sound doesn't completely go away and I then have issues with the top layers of the print having spaces between the lines (even with 5 solid top layers being laid down on 50% infill.

Thoughts? Suggestions?

Is it scraping the whole time, or just during retractions? If just when its moving and not printing (The problem I had) you can adjust the Retraction Vertical lift setting in the extruder tab of S3D to fix this. I set mine to .4mm

Thanks for the reply! I will be sure to double check this evening but I think it is happening during actual printing (I will report back tonight).
