@pipersw said in temperature variation (since update to 2.0.4):
I have fluctuation if I set PWM to 50% and 40W cartrige, but none if PWM set to 100%, but I have the warning hoverheat message.
So I set PWM to 100%.
Reducing the PWM percentage may stop the warning but it won't actually save you from what the warning actually warns about. In the case of a fail-on scenario, PWM has stopped working anyway.
