Depending on the type of extruder, many printers use a value between 2 and 7 mm (e. In fact, one of the main purposes of retraction is to eliminate stringing. Issue was resolved by reducing retraction settings. We suggest setting a retraction speed between 30 and 60 mm/s , again the perfect value depends on the printer/nozzle/filament configuration. The default retraction distance on Cura is 5mm. The aim of the retraction test is to achieve a "cleaner" part without material residues in the movement areas of the hotend. Only increase this until no more stringing is observed. by Jackson O'Connell. 4. Go to Printer Settings. test the right retraction distance and retraction speed. Unfortunately without knowing exactly what printer you have (there's about half a million various Ender-3 models) or what modifications have been done to it. Distance: One of the most important retraction settings has to be distance as it is the length of filament that is pulled back by the extruder every time retraction occurs.
