The retraction speed is how fast your filament will retract the filament from the extruder. 2 mm; Direct drive (S1): 2 mm; Retraction Speed. Retracting only a very small distance won’t probably solve stringing, whereas exaggerating this value will cause no plastic to be available in the nozzle during the initial moments of the next extrusion. Too slow and pressure doesn't get relieved in time and hotend oozes. Another critical aspect is the retraction settings. That's with a direct drive and it almost always depends on what temp you print at, and what material. It is expressed as a value in millimeters per second. A low retraction speed value can cause the TPU to leak out as retraction is taking place, creating a blob that the nozzle may pick up and drag across the space as it travels. 6 and 0.
