Retraction TEST

thingiverse

I used this test to fine-tune my retraction settings, including retraction distance, extra restart distance, retraction vertical lift speed, coasting distance at the end of moves, and filament temperature. To thoroughly evaluate different travel distances, I created test shapes with spaces between them measuring 10mm, 20mm, and 40mm. My printer is a CTC Bizer model that has been upgraded with parts from Thingiverse. My extruders are two Titan models (Chinese clones) and my nozzles are two E3D v6 units (also Chinese clones). The screenshot from Simplify 3D shows the settings I used for printing EXCELVAN PLA, which involved a temperature of 210 degrees. Although there is some stringing between the first two shapes in the print job, it's not excessive.
