What is the tolerance of placement for fixtured mode and non-fixtured mode?
Full Fixtured (FF) is extremely sensitive to part placement. If it moves slightly to the left, right, up or down, then it will be considered a defect. If it is missing it is also a defect. FF is useful when you want to see small defects and you know the part is extremely controlled in its X/Y positioning. If you can’t control the placement, then you should consider Non-Fixtured (NF). NF is relatively insensitive to part placement. For example, let’s say you have Eyebot learn a cellular phone on a gray background in NF. Then you place it in RUN. If you move the cellular phone slightly up, down, or right or left, you will notice that the score does not move down much, assuming your lighting is diffuse. If you rotate the phone, however, the score will drop because it will be considered a defect. Similarly, if you create a defect on the phone, it will also make the score drop. If NF appears to sensitive to placement and is not acting as described above, then it could be because: a. You may
