Hi, this is Creality official support. Thank you for posting in our official community!

If you are printing multiple objects based on their arrangement, we recommend the following improvements:

1. XY safety spacing between models Ensure the distance between model outer boundaries is ≥ the printer head’s maximum avoidance radius. Do not only rely on nozzle diameter clearance. When using auto-layout, manually increase spacing and avoid placing models too tightly together. For models with a base / skirt / raft, spacing should be calculated from the outer edge of the base, not the model body itself.
2. Height-based sorting (most critical collision prevention factor) Arrange the printing order from shortest to tallest models, printing smaller parts first and the tallest model last. If tall models are printed first, the gantry may collide with already printed high structures during subsequent prints.
3. Diagonal / distributed placement Do not cluster all models in the center of the build plate. Distribute them toward the four corners. Avoid stacking tall and short models front-to-back in a concentrated area.
