Eryone Thinker S hotend fix

thingiverse

This is a straightforward solution to prevent the bowden tube from lifting off and causing a clog in the hot end. Use the cutter tool to trim an extra piece of bowden tube to 36mm, then insert this cut piece into the hotend. Place the small washer on top of the bowden tube, ensuring the tapered side faces upwards. Now thread the bowden fitting back into place. The washer will be snug as you push it past the threads, and once it's clear, it will float a bit loose inside. To verify that the washer is centered, feed some filament through the main bowden tube first, then push it into the hotend. When you tighten the fitting, you'll know the washer is in its correct position. If you're short on time to watch a video, search for "Ender 3 hotend fix" online - there are plenty of tutorials available, and this fix is essentially the same. I've already included the pre-sliced G-codes for the Thinker printer, so you can print it straight away if you prefer.
