Thanks for the reply. I emailed Blue Eagle Labs about the Haydn rods before making this post and they said "When it comes to temperature, the bottleneck would be the magnets. N50 magnets are good to 100C. "

Assuming the E3DV6 is water cooled what would be the maximum operating temperature for the smart effector? I am planning a build with a high temperate heated chamber and was wondering if the smart effector would be an option.
