I would expect to have:

  • 1 layer: 0%
  • 2 layer: 35%
  • 3 layer: ~60%
  • 4 layer: 100%

Am I missing something?

"Full fan speed at layer" is definitely confusing. It means, that at layer 4, this limiter will stop limiting and fan will be on its target speed. Thus:

  • layer 1: 0%
  • layer 2: 12%
  • layer 3: 23%
  • layer 4: 35 % I am unsure, why 5th layer gets to 80~90 %. Too short layer time I guess?

What is the purpose of default fan speed then? It doesn't affect the "minimum PWM that my fan needs to work" as explained in the details. I also checked Run the fan at default speed when possible but no change.
