Perhaps to fix a problem, or to try to get the perfect print. Retraction range: 5 mm Retraction speed: 45 mm/sec Part-cooling fan: This should be on. We only need to consider 2 factors here. As the Ender 3 has a Bowden style setup, retraction settings are much higher. Based on your results, adjust either the travel speed or the retraction distance and reprint. TPU - 230 °C - Layer thickness 0.2 mm - Retraction 1 mm - Print speed 15 mm/s PLA for reference - 205 °C - Layer thickness 0.2 mm - Retraction 1 mm. Download the Retraction cube files here. Use the lowest amount of retraction that yields the best balance between print quality and risk of jamming. More retraction = higher chance of jamming. Only change 1 setting at a time. The base of the printer containing the print bed and the Y axis (back and forth) control as well as most of the wiring are already assembled before leaving the factory. Hi, I noticed the same thing with some small models on my ender 3, the solution was to double the retraction, but the most important things were the speed and the temperature (PLA hatchbox), I went about 30% of the speed and went from 200°C to 190°C (200 only the first layer) my bed was 50°C. We only need to consider two factors here. Cura Retraction Settings on Ender 3. Retraction: PLA is a stiffer material, as well as thus it can be easily tuned. Following are photos of a stringing test with various combinations of settings. For many reasons you may want to tweak a preset Cura profile. Simple cheat sheet showing a range of values for the most important settings in the Cura slicer for CR-10 and Ender 3 (and variants.) Retraction: As the Ender 3 has a Bowden style setup, retraction settings are much higher. For PETG you should choose a shorter retraction of 4 mm, while for ABS you should choose 6, mm with a faster retraction speed of 40 mm/s. To quickly and easily tune your settings to achieve optimal retraction, download the cube retraction print here, and print it with your current settings. Retraction distance: 5 mm Retraction speed: 45 mm/sec: Part-cooling fan: This should be on. Ender 3 Stringing – Which (Retraction) Settings Help? A default profile will not give you any idea how much you can change a setting. Too much retraction. Retraction Enabling: First, go to the ‘Travel’ settings and check the ‘Enable Retraction’ box to enable it We typically use about 2-3mm on our Bowden machines when fitted with our Tough Tube and 3-4mm when using stock PTFE tubing with the larger inside diameter. The perfect Cura settings for your Ender 3 ... Retraction is broken down into two main settings: Retraction distance Retraction speed Essentially, retraction is a tool that reverses the extruder motor to relieve pressure on the nozzle during travel. TPU - 205 °C - Layer thickness 0.2 mm - Retraction 2 mm - Print speed 15 mm/s. Starting with the Ender 3 default settings in CURA is a good start. The Cura retraction settings on Ender 3 printers usually include different settings and the ideal and expert choice for these settings will be as follows. Hopefully, without pressure on the nozzle, no excess material should be extruded. However, it may take a few tries before you find the best setting for you and your print.
