Yes, I have been been drying the filament. This latest batch was glass infused nylon and it arrived from shipper with over 50% humidity. It took 3 days in the dryer and I could not get it below 20%.

This latest experiment is one of the best so far but still not acceptable. It's odd that the top and sides of the parts come out looking like they were professionally machined. So beautiful it almost hurts to look at. The surface under the supports is just terrible.
