Coasting and wipe distance are two settings that can affect the quality of your 3D prints.

Coasting is a setting that tells the printer to stop extruding filament a little bit before the end of a perimeter or an infill line. This helps to reduce the pressure in the nozzle and prevent oozing or stringing. Coasting can also reduce the amount of blobs or zits that appear on the surface of the print. However, coasting can also cause gaps or under-extrusion in some cases, especially if the coasting distance is too large or if the filament is not viscous enough.

Wipe distance is a setting that tells the printer to move the nozzle along the perimeter or the infill line after it stops extruding filament. This helps to smooth out the end of the extrusion and reduce any excess filament that may ooze out of the nozzle. Wipe distance can also improve the surface quality of the print by hiding any imperfections or seams. However, wipe distance can also cause over-extrusion or dragging in some cases, especially if the wipe distance is too large or if the nozzle temperature is too high.

Both coasting and wipe distance are useful settings that can help you achieve better 3D prints. However, they are not mutually exclusive and they may interact with each other in different ways depending on your printer, filament, and model. Therefore, it is important to experiment with different values and find the optimal balance for your specific situation. You can use a test model like this one (https://www.thingiverse.com/thing:1363023) to see how coasting and wipe distance affect your prints and adjust them accordingly.
