What retraction settings should you use for ABS and ASA?
Your printer's own: shipped ABS and ASA profiles use 0.7 to 0.8 mm on direct-drive Prusa and Bambu printers (0.4 mm for Bambu ABS) and 2.5 to 6.5 mm on Bowden.

AnswerHardware
Print a retraction tower (OrcaSlicer tests 0 to 2 mm in 0.1 mm steps, a new length every 1 mm of height) and keep the shortest length whose band prints clean.
AnswerTroubleshooting
Yes. Prusa says a lower Lift Z improves stringing. Keep the hop low (Bambu Studio ships 0.4 mm) and lift on a slope, spiral or ramp instead of straight up.
AnswerHardware
Bowden Ender-3, Pro and V2: 4 to 6.5 mm (Cura gives the Ender-3 and V2 5 mm at 45 mm/s). Direct-drive S1, S1 Pro, V3 SE and V3 KE: 0.5 to 1.2 mm.
AnswerMaterials
Shipped PETG profiles retract 0.4 to 1 mm at 30 to 45 mm/s on direct-drive printers and 2.5 to 8 mm on Bowden printers, close to each printer's PLA values.
AnswerMaterials
Shipped PLA profiles retract 0.4 to 0.8 mm at 30 to 50 mm/s on direct-drive printers and 2.5 to 6.5 mm at 45 to 70 mm/s on Bowden printers.
AnswerHardware
Direct drive: 0.7 to 0.8 mm, as Bambu Lab, Prusa and Creality profiles ship. Bowden: 2.5 to 6.5 mm (Prusa MINI 2.5 to 3.2 mm, UltiMaker S5 6.5 mm).
AnswerTroubleshooting
Soft filament is pulled up into the heatbreak and jams, the gear grinds it, and lines restart with gaps. Bambu Lab and Prusa's MK3S cap it at 2 mm.
AnswerHardware
How far Bambu Studio and OrcaSlicer pull filament back before the cutter cuts it at a filament change: 18 mm by default, and the field only accepts 10 to 18 mm.
AnswerHardware
Printer settings > Extruder > Retraction: Bambu Lab profiles ship 0.8 mm length and 0.4 mm Z hop. Per filament: Filament settings > Setting Overrides, which wins.
AnswerHardware
Print settings panel, Show Custom, Travel category. Most fields are hidden: search "retract". Cura's base Retraction Distance is 6.5 mm at 25 mm/s.
AnswerHardware
Use your profile's value: 30 mm/s on Bambu Lab printers, 35 to 45 mm/s on Prusa's direct-drive printers, 70 mm/s on the Bowden Prusa MINI, 25 mm/s in Cura.
AnswerMaterials
Start from your slicer's TPU profile: 0.4 mm on Bambu Lab X1 Carbon, P1S and A1, 2.5 mm on Prusa MK4S and CORE One, off on the MK3S, 3 to 8 mm on Bowden printers.
AnswerHardware
Pulling filament back before a travel move so the nozzle stops oozing: 0.8 mm at 30 mm/s in Bambu Studio's X1 Carbon profile, 3.2 mm at 70 mm/s on a Bowden Prusa MINI.
AnswerHardware
Z hop lifts the nozzle after a retraction so travel moves clear the print. Bambu Studio ships it on at 0.4 mm; UltiMaker Cura ships it off, set to 1 mm.
AnswerTroubleshooting
Stringing is plastic leaking from the nozzle on travel moves. Check a wet spool first, then heat (UltiMaker: 5 °C lower per print), retraction and long travels.
AnswerTroubleshooting
Shipped profiles run PETG 20 to 35 °C hotter than PLA, and its melt draws out into threads. Dry it, drop the nozzle 5 to 10 °C, and expect a few fine hairs.
AnswerHardware
0.2 to 0.4 mm on a 0.4 mm nozzle. Bambu Studio and OrcaSlicer ship 0.4 mm, PrusaSlicer 0.4 mm on the Prusa MK3S and 0.2 mm on the MINI, Cura's Creality profiles 0.2 mm.
AnswerHardware
Keep your profile's type: Bambu Lab printer profiles ship Auto, which picks Slope or Spiral per travel. OrcaSlicer's own default is Slope at a 3° Traveling angle.
