I've come for help! I'm trying to diagnose some new issues. I've been printing glass fiber nylon for multiple years with no issues on my upgraded Creality CR-10s. However now I'm getting crazy oozing and heat creep that only results in a clog once the print is finished. The first time it happened I near fully disassembled and reassembled the hotend to make sure all the connections were tight but the problems persisted. I've always printed the polymaker glass fiber nylon at 280c which is the bottom of their suggested range but I tried reducing it to 270 to see if maybe my thermistor was off and giving me a low reading. That made zero difference. Heres all the upgrades the machine has: Micro Swiss All-Metal-hotend w/ direct drive kit and an A2 hardened steel nozzle a satsana fan shroud with 4020 blower for parts cooling plus a 4010 noctua heatsink fan. In my general troubleshooting inexperience my thoughts are to maybe get a more powerful heatsink fan, upgrade the heatbreak, or both but I feel like that would only solve the heat creep issue. Also to ward off an obvious question, I am tighting all connections again once the hotend is up to temperature.

Brilliant question! Never. That would 100% explain the heat creep. Googling around it looks like boron nitride paste is the go-to. Any chance the heat creep is related to my oozing? I'm open to upgrading the hotend I just don't know what would be compatible with the microswiss direct drive.

Luckily I had a spare head and I already installed it. I was wondering if I should just throw the old one away or not. I imagine you might be able to remove it using a screw extractor kit. Probably depends on the material the nozzle is made of though.
