Review on High-Quality Assembled Metal Extruder Hotend for Additive Manufacturing Process – Top Printers & Products by Michal Adach ᠌

Be sure to make sure that all elements fit snugly together and are not too loose / tight. Check that the plastic feed tube is fully inserted into the hot end and is firmly fixed. I bought this hot end twice, because. for the first time somewhere messed up during assembly. As a result, there was a jam inside, the feed mechanism began to slip, the print became of very poor quality. The plastic began to slowly but leak through the threaded connections and flooded the hot end from the outside. It was not possible to clean the thread at home, as a result I ordered another one. The second collected more carefully, works fine.
