Thanks for the follow up. Two observations. First, I did see it extrudes more when the first layer percentage is changed but it isn't enough to make the paths touch. Secondly, I have the filament diameter and flow rate identical on all my other slicers without issue. So, if I did increase my flow either by extrusion multiplier or filament diameter size adjust I would, in effect, be over extruding and ending up with inaccurate parts. I can see that when my part gets to layer two and the rest that follow there is no issue with under extrusion. Included screen grab. All setting the same except first layer percentage 80% and 300% for exaggeration. Which ever one I choose I have to get the tip so close is make brim on ABS useless. Its paper thin almost transparent.Set at .15 first layer
