Here are the details of what options do and what can be done. Some options can be turned off completely only one option can be selected.
This option is able to be unchecked to eliminate all undercut milling and calculation for units.
Undercut 3+2A Finishing
This is the default undercut milling option for the supported types. This is set to default as it's faster to calculate and more reliable to mill due to the efficiency of fixed axis milling. This still angles the units to 4 different angles on each side to reach almost all the areas of detail.
Undercut 5A Continuous Finishing
This undercut option is for more detailed finishing. This increases the calculation time typically by 30-40% at the time of this writing but does give more details in various areas that are missed in the 3+2A Finishing method. Offset values need to be increased in this option due to increased movement.
Machine must be calibrated for this option to function properly as it's dependent on the zero point defined. Performance varies from machines because of this.
Crown and Coping milling speed options
1mm Exterior Finishing (Default)
This option utilizes the 1mm tool for finishing the unit. This is the default and standard for milling dental units.
2mm Exterior Finishing (Less detail/Faster milling)
This option is to enable 2mm finishing which will decrease milling time but also reduce the detail of the exterior finish of the unit. This also disables 0.6mm and 0.3mm finshing of the top of units for Full Anatomical Crowns.
Margin Chipping Reduction
Prepline 2.x contouring
This option is default to the roughing operations follow the margin line contours to prevent large steps from being chipped off during finishing. This occurs with units with steep transitions in the Z direction of the disc. It can be unchecked if speed is a requirement.
Select this option if restoration has mix of preps & hybrid/2-Connect units
This option is work with designs that have a combination of CAD geometries and
[Error fix] Check if hybrid cavities did not mill out
When selecting hybrid or glue object types for the cavities that do not mill out or look milled out in simulation, this option is available to enable additional curves to be utilized. This option is not on by default due to the potential air milling for standard designs with all the inputs for the design. Another option is to delete the curves defining the base of the unit and adding manual margin curves to enable the finishing of the cavity and the exterior of the unit.
Model Milling Specific Options
1mm Finishing of die bottom half (Mill die for removable use)
This option enables more detail to finish the model. It's off by default as the area is typically a non-cosmetic area. Increases milling time.
2mm Finishing of model top side (Default)
1mm Finishing of model top side (More detail and slower mill time)
1mm Undercut Finishing of model top side (Most detail and slowest mill time)
One of these three options can be utilized to finish the model. The descriptions do explain that the increase in times and detail.
