I understand they can’t guarantee results for anything but Proofgrade but … that is unfortunate. It would be nice to have 3d Engrave with manual settings for max power, etc.
As far as I know all Proofgrade settings are simply presets for the manual options. When you have something configured to use a Proofgrade setting you can switch it to manual settings and the fields will be populated with settings corresponding to the previously-selected Proofgrade option.
For example, if I have something set to 3D Engrave on Proofgrade Medium Basswood Hardwood:
Note that if I had any other Proofgrade option selected (Photo, Graphic, etc.) then I’d end up with different manual settings when following these steps.
As far as I can tell there’s no difference between using the Proofgrade settings and the equivalent manual settings.
Our design team works to create great presets for all of our Proofgrade materials. Since materials react differently to engraving, some materials have different options available than others. @Jules posted the Proofgrade materials that have 3D engraving available so far.
