Retraction Dual Tower Test

prusaprinters

<p>I liked Stephen Albert's retraction test, but wanted something smaller that printed quicker (6-9 minutes rather than 15+). With rounded corners and only a thin strip of plastic connecting the two towers, it reduced the amount of plastic without reducing the stability of the part. And, I found that any of the printing artifacts (stringing, blobs, or "residue spikes" were evident within the first 1cm, so no real need to make it taller than that.</p> <p>The base are 5mm radius 1mm tall cylinders and the two towers are 2.75mm diameter 10mm tall cylinders separated by 22.5mm.</p> <p>I believe the Cura 3.6 settings that helped me the most print this without stringing or little "residue spikes" were:</p> <p>Shell<br/> Shells: 2 (I think higher would be even better)</p> <p>Material<br/> Printing Temperature: 180 C (printing PLA)<br/> Enable Retraction: Checked<br/> Retraction Distance: 6 mm<br/> Retraction Speed: 20 mm/s</p> <p>Speed (I believe Outer Wall Speed and Travel Speed were the most important here)<br/> Print Speed: 150 mm/s<br/> Infill Speed: 150 mm/s<br/> Outer Wall Speed: 50 mm/s<br/> Inner Wall Speed: 100 mm/s<br/> Travel Speed: 120 mm/s</p> <p>Travel<br/> Combing Mode: All<br/> Z Hop When Retracted: Unchecked (It's unchecked by default)</p> <p>I hope this helps!</p> <h3>Print instructions</h3><p>Unassociated tags: retraction test<br/> Category: 3D Printing Tests</p>
