This is a guide to understanding the various colors that may become visible up while setting up a job or moving units around.
Some of the colors are to warn you of a detected issues, but do not prevent you from creating a file to output to the mill if you choose to calculate a job. Ignoring these visual and text warnings can result in broken units, tools, and/or machines.
White teeth units
This is the default visualization color for imported STL units.
Partially red highlighted areas
Indicates that that area of the unit is outside of the boundary of the millable material.
Either rotate the unit within the limits of the machine's angle limit or go up the next available disc size. The image below shows the bottom and top of the unit for the side; the smaller views show what to look for.
All red highlighted unit
If the entire unit is highlighted red, it will not mill properly and calculation will not start. Some known reasons for red highlights are:
- A part boundary offset intersects another unit surface.
- The rotation of the unit has a cavity or drilling axis that is angled greater than the configured warning limit of machine selected. This unit is also too small for the disc size but the full red warning shows up when it is not possible to mill. Millbox will typically snap back the rotation to a millable angle.
All Yellow highlight unit
The unit may have issues, like it is near an equipment boundary or close to being un-millable state (an all red highlight). The clip below shows the unit changing to all yellow when moving past the material boundary, then turning to all red when the unit milling offset is touching the equipment.
Flashing yellow sprue
The sprue is likely not attached to any material. Flashing yellow does not warn if the material is too thin to sprue to. The clip below shows the sprue changing to flashing yellow when the unit is rotated. Looking from the top down, you can see that the sprue is not fully attached to the disc and can potentially fall off. Millbox does not warn you if you choose to calculate with a flashing yellow sprue present in your job.
Purple highlighted areas
Millbox detects potential undercut areas by highlighting them purple - More information here on the undercut visualization feature.
