Do you have any idea if the cooling fan duct was designed to work with am E3D silicone sock? I tried installing the cooling fan duct with a sock and it didn’t sit correctly and pushed the duct below the plane of the nozzle. With the sock removed, running the cooling fan at 80% I noticed the heater couldn’t maintain the hotend higher than 215C, even though it was set to 235C.
Has any else had this problem? I think the ultimate solution is to redesign the cooling fan duct to include the extra spacing needed around the hotend for the sock, but I figured I would see if anyone did it before trying myself.
