[QUOTE="Brett Hansen CDT, post: 343421, member: 3194"] Here are the values I have been using for years and our fits are great. Cement .020 Extra Cement .060 Dist to margin .1 Smooth dist .2 Drill radius .51 Drill Comp .53 The last two values are very important. They are determined by the the smallest tool that your milling strategy uses to mill out the cavity of the crown. For us, that tool is a 1.0 mm tool. That means I need those last two values to be a little more than half of the diameter of the 1.0 mm tool. Your drill comp offset is really large and that seems to be the one that may be causing your issues with fit. Good Luck! Let me know if it gets better. [/QUOTE]
