<p>I'm using an Ender 5 with standard PLA and Creality slicer 4.8.2.</p>
<p>How can I deliberately maximise stringing, and if possible get it to be as consistent as possible.</p>
<p>My aim is to have &quot;thousands of hair like threads strung between two rocky pillars&quot;.</p>
<p>If possible I'd like to do this in the slicer with PLA, rather than using cotton or some other material after the model has printed.</p>

I've not researched if a specific slicer will allow a negative retraction, but if it's possible, it's likely to create adjustable stringing.</p>\n<p>If negative retraction is not possible, one can identify the retraction segments in g-code of the print and find/replace those values with extrude rather than retract. My slicer, Simplify3D does not support reversed retraction, but the code is clear when examined with a text editor:</p>\n<pre><code>G1 E-4.0000 F2400\nG1 Z0.300 F1200\nG1 X118.760 Y117.415 F12000\nG1 Z0.250 F1200\nG1 E0.0000 F2400\nG92 E0.0000\nG1 X122.415 Y113.760 E0.0972 F900\nbuild g-code removed for clarity\nG1 X118.760 Y117.415 E1.5303\nG92 E0.0000\nG1 E-4.0000 F2400\nG1 Z0.300 F1200\nG1 X158.280 Y117.216 F12000\nG1 Z0.250 F1200\nG1 E0.0000 F2400\nG92 E0.0000\nG1 X162.216 Y113.280 E0.1047 F900\nbuild g-code removed for clarity\nG1 X158.280 Y117.216 E1.5902\nG92 E0.0000\nG1 E-4.0000 F2400\nbuild g-code removed for clarity\nG1 E0.0000 F2400\nG92 E0.0000\nG1 X162.415 Y113.760 E0.0972 F900\nbuild g-code removed for clarity\nG1 X158.760 Y117.415 E1.5303\nG92 E0.0000\nG1 E-4.0000 F2400\n</code></pre>\n<p>All entries beginning with G1 E-4.0000 represent the 4 mm retraction called by the slicer. One could search for just that code and replace it with a positive value. Some experimentation is indicated to accomplish the desired result. The F value is feed rate and presents another value to adjust.</p>\n<p>Pursuant to Oscar's comment, I overlooked the lack of movement as a factor. He is correct, such a modification is likely to create a blob. As a possible compensation, a better modification would be to create a custom extrusion code with a reduced flow rate, using the existing code as a reference.</p>\n<p>This starts to complicate the process substantially, requiring far more calculations and edits. I suggest that it could yet be accomplished, but would be more easily done so with post processing of the code via Python or similar, with which I am not qualified to address.</p>\n"}, {'answer_id': 19770, 'author': 'Perry Webb', 'author_id': 15075, 'author_profile': 'https://3dprinting.stackexchange.com/users/15075', 'pm_score': 2, 'selected': False, 'text': '<ol>\n<li>Eliminate retraction in slicer.</li>\n<li>Print at a higher hot end temperature; something like +10°C higher than recommenced temperature.</li>\n<li>Slow down speed hot end moves when not printing.</li>\n<li>Maximize hot end movement without printing where you want strings.</li>\n</ol>\n'}]
