Yet another retraction test

thingiverse

Simple Retraction Test with Two Cylinders and Two Cones. The cylinders are ideal for testing combing/wiping/coasting settings. These settings have less impact on cones as they narrow down. This makes cones more difficult to print cleanly and are useful for fine-tuning finer detail prints where combing/wiping/coasting doesn't help much. The narrow taper on the cones also makes this a good test of hotend cooling, as fine points will melt and fall apart if cooling is poor. Print using the settings you'll be printing in - it's tempting to speed up by increasing layer height, but layer height can affect stringing.
