I spent quite a while dialing in my TPU settings. I know that they will be different for each printer, but the settings listed here in the video should give you a great starting point. It will also give you an idea of which particular settings to focus on.
IMPORTANT: In the video I state that the fan had very little impact on the quality of the print. After more work, I've discovered that the fan does play a role in layer adhesion for softer TPUs. I found when printing large flat surfaces with the fan speed at 100%, I had layer separation issues on the first couple of layers. I recommend fan sped of 30%-50% to correct for this.
