Hi everyone, I'm having trouble getting a stable temperature from my Hemera. the fluctuation is in a range of +5 degrees to -5 degrees. this seems (compared to other hotends) way too much. Installed it on an Ender 5 running an SKR 2 board. so far I tried, turning on/off the part cooling fan and I ran several PID´s, but no luck. Anybody has a suggestion of something that I am missing or could try ?
