gr5 897 Posted February 12, 2015 in how to clean burnt nylon off the heater block Not sure. Do you have a heat gun? With PLA it softens at a much lower temperature so it's easy to work with - just heat it up and pull it off with a wooden stick or a screwdriver or something. With Nylon you have to get much hotter and have to be careful not to melt the fans and wiring insulation. I guess I would remove the left-and-right fans assembly and let it hang by wires. If it's stuck on at that moment I would turn on the heater block to 200C. Wait a few minutes for things to really soften up (240C is much too hot as the Nylon might caramelize). Then pull the fan shroud off and then attack the blob of nyon with a sitck. A hair dryer or heat gun might speed up the initial warm up step. Share this post Link to post Share on other sites
