In the last few days, I have had four crowns come out of my mill with flat cusps or margins. I use the Zenotec Mini. I do not have the advanced software. The crowns are being nested in the correct size puck. I called Wieland. They told me my air pressure must be at least 7 bar. When we bought the mill in December, the Ivoclar reps told me it needed to be over 6 bar. Our air pressure is usually around 6.5 bar. The issue with the flat margins/cusps had only happened once or twice before this week. Anyone else run into this issue?
