Backlash Backlash is a mechanical issue in 3D printing where there is unintended movement or slack in the printer's motion system. It occurs when the direction of movement changes, causing a delay in the response of belts, pulleys, or gears. Backlash can result in artifacts such as misaligned layers or uneven dimensions, especially in prints with intricate geometries. Addressing backlash involves tightening belts, ensuring proper gear alignment, or using backlash compensation features in firmware. Maintaining a well-calibrated printer helps minimize the effects of backlash and improves overall print accuracy. |
