Abstract: In one example, a roller control process for a 3D printer includes stopping the layering roller rotating at angular home before the roller reaches linear home at the end of a fusing pass, measuring the duration between when the roller reaches angular home and when the roller reaches linear home, and, if the duration exceeds a threshold, then stopping the roller rotating at angular home at a distance closer to linear home in subsequent fusing passes until the duration does not exceed the threshold.
