Being a late bloomer in reprap, I just discovered PID autotune.

Nozzle temperature fluctuations may be caused by incorrect PID settings.
Shouldn’t we all (reprap builders), right after our build is finished, autotune PID with M303 for better results?

Yeah, I finally switched from sprinter to marlin and the auto tune is an awesome feature

Agreed! After autotuning, the graph of my hotend temperature is dead flat (once it’s up to temperature of course)
