Hi everybody, these days I have problems with my PMMA fittings. After couple of calibrations all crowns and bridges are too tight so I have to manualy adjust to fit them on the model. This happend with PMMA, zirconia fitting is great. Was trying to change settings in 3Shape and also in the machine but it doesn't work. So maybe one of you have experienced the same issue and can help me. My current 3Shape PMMA settings: Drill compensation offset:1,500mm Drill radius: 0,600mm (milling with new drill compensation and without it doesn't make difference for me) Have tried different settings but did not work. I am using Wieland burs. I have tried changing cement gap but the result is the same, too tight, so I guess cement gap doesn't effect the milling. Please help, thank you in advance.
