I run this straight out of the Sunlu dryer. Do not use in the AMS. I use the Bambu TPU profile with no mods on the engineering plate. Prints great with no issues. Flexibility is like an o-ring or a windshield wiper blade. Use a glue stick or other release agent, as it sticks to the plate pretty strongly.
