Whenever I mill out zirconia crowns designed on 3i flex abutments, I have to jump though many hoops, fattening the emergence profile, all new burrs, and a good chuck cleaning, to get it to mill and even then it’s a high chance of the emergence profile of the crown blowing . Even have to import an manually set parameters sometimes to get a good crown. This is on a Ceramill Motion 2, nested with Ceramill’s software.

Watched the mill and blows out when milling out the abutment hole midway through.

Anyone experience this? Any ideas?

Can you simulate the CAM before you mill? That should show you any issues with the milling strategy before you actually send the job to the mill.

I don’t believe you can simulate with the Ceramill (AG) CAM software. It’s just usual that only 3i flex abutments do this, everything least mills fine
