1. Increase the pumping distance.

2. Increase the pumping speed.

3. Reduce the distance between models when printing multiple objects.

4. Increase the empty walking speed.

5. Add a cooling fan. In some cases, a fan can be used to blow on the printed model.

6. Try to print a single model to eliminate the movement of multiple objects.

7. Under normal circumstances, the printing temperature can be appropriately reduced to reduce wire drawing.

TPU: it usually takes longer to pull back, but in order to ensure printing, you may be forced to have a shorter or no return so that you can print smoothly.

ABS, ASA and other engineering consumables: adding cooling fans will cause model printing warping printing failure.
