      I have now completed an auto tune of the hot end "M303 H1 P0.15 S210 "
      This is the result
      Heater 1 model: gain 568.0, time constant 185.4, dead time 14.0, max PWM 1.00, in use: yes, mode: PID
      Setpoint change: P4.2, I0.02, D40.8
      Load change: P4.2, I0.15, D40.8

      However, when the hot end reached the set temperature, I switched on my secondary cooling fan at 50% speed and the hot end temperature dropped dramatically and took a long time to recover.

      How can I improve the response time of the heater?
