Hello.
I tried doing this today.
Inner part about 7"x9". Rough with the 1/4 end mill and finished with 1/8 ball mill. Shorten my step over by half of what was suggested.
I’m guessing that I need some smaller bits for this to look better?
I brought the png using the model tab.
Also is there way way to import the png darker? The image I’m darker and lighter than how it imports in.
Another trick for more depth in STLS is if it’s quite 3d removing anything behind the image adding thickness using something like meshmixer will allow you to make the front portion more pronounced.
In V7 there was an option, “Remove Z Height” that would remove that height from the bottom of the STL. Looks like it’s gone in V8. Perhaps to simplify the editing of solid components??
You can still make the workpiece thicker than actual size, so the built in base becomes smaller.
Another option is to load the STL into a tool such as Microsoft’s 3D Builder and edit it there to remove any unwanted thickness, then save that under a new file name.
