Gray paint does not have a liquid consistency when exiting the nozzle. I have an Ultimaker 2+ Advanced and have tried everything. This filament is said to be very sensitive to moisture, which explains why prints don't produce smooth layers. I've also tried taking the filament straight out of the box and printing, but got the same inconsistent results. When printing a layer, the extrusion stops for a microsecond, resulting in a gap in the layer.
