Thank you for looking into it, I thought it must be the Gcode. I installed 3.2 Beta and had the same under extrusion in that area. The only thing that gave me success in that area was to turn up the heat by 10° and over-extruded by 10%. The part turned out reasonably well that way. I love the features in 3.1 and 3.2 compared to 15, so I hope they can find a fix.
