I’ve just removed my E3D v6 from my machine as I think there’s an issue with my thermistor. Turned it over and saw this yellow powder coming out of it, its almost like sulfur. I bought the v6 as an assembled kit and haven’t touched it until now after printing nylon, abs and petg with it on and off for the past few weeks. Any idea what this powder could be? Highest i’ve taken the temp is 265c, so still within its limits. Thanks. http://ift.tt/2deyYSd
