If retraction distance is too high, your 3D printer is more prone to jamming since the heated end of the filament is drawn further back into the cool Since the most likely scenarios are the filament being retracted too far back or not being retracted and primed quickly enough, which will both result in under-extrusion after a retraction due to the Ender 3 not being able to move the filament back into the nozzle in time, modifying the retraction distance and the retraction speed (or Dear all, I am using an Eder 3 and decided to replace the original printhead with a Sprite Extruder Pro Kit. Skip to main content. 75mm PLA Nozzle temp 200, bed is 50 For the sake of these retraction tests I used the same speed settings as the thingiverse description, 30mm/s print speed, travel speed 20mm/s First was 2mm at 40mm/s Second was 4mm at 40mm/s Third was 6mm at 45mm/s I want to basically eliminate all stringing as much as possible. Really, I didn't believe until I saw. 5 Retraction speed 25, 45, 55, 75 I also tried changing just the prime or just the retract speed. If your printer has a direct drive extruder, you may use the same speed interval but reduce the retraction distance to about 0. 8 like in the manual. I didn't change anything else. Travel Speed. However, too long of a retraction distance can also cause a hot end jam, so be careful. After many hours of testing, I’ve found that the best Ender 3 retraction settings include a retraction distance of 5. 2.

Over time, this can cause the coupling on top of the hot end to loosen its grip, allowing a gap to form. As a rule of thumb, the right PLA retraction settings are about 7mm to 9mm retraction distance at a retraction speed between 40mm/s to 50mm/s, for printers with a Bowden extruder. This gap can be caused by improper installation of the PTFE tube, or can increase over time due to retraction movements of the filament, which pull back on the tube. 6-8mm Try increasing the movement distance after retraction. 5mm. The extruder arm is directly responsible for how tightly the extruder gears grab the filament, which can trigger a squeaking sound when the tension is way too high.
