Flatness call out
WebSo for a consistent-width gap, this "light and ruler" test would make the issue appear worse in the centre, which naturally makes us think "the bed is warped". The wide angles of the light sources also means that very little light is hitting the gap perpendicularly or straight-on, and instead hits this gap at an angle. WebFigure 2. Height Gage on Columns set up to evaluate flatness. In application, one way to physically measure flatness is to use a height gage, as we can see in Figure 2. To use the height gage correctly, the part to …
