      I'm troubleshooting poor layer quality and I'm wondering if it's related to cooling. Is there an efficient way to determine the PWM for a layer fan? right now it's set to 500 but I know it can go up to 25000.

      This is the fan I'm using Fans

        Since you can send the PWM frequency command while the fan is running I would just start low and increase it a hundred or so at a time to see how it behaves.

        How do you think the cooling relates to poor layer quality? How will changing the fan PWM frequency help?

        Is the fan running at all? Is it running but too slowly?
