Need Advice on Tuning PID for a Hotend on Duet 2 WiFi
-
Hey everyone,
I’m fairly new to the Duet 2 WiFi and am loving the level of control and customization it offers. However, I’m having a bit of trouble fine-tuning my hotend's PID settings. I’m using a genuine E3D V6 hotend, and while I’ve run the auto-tuning process a few times, the temperature fluctuates slightly during longer prints- usually by about 2-3°C.
I’m wondering if there are any tricks or tips you guys might recommend for better stability? Should I manually tweak the PID values after auto-tuning or increase the sample time? When I was searching about this I came across these resources/articles https://docs.duet3d.com/en/User_manual/Connecting_hardware/Heaters_tuning and UiPath Installation and as per them I have to set valve for the same but I have no idea how to do it.
Also, if anyone’s had experience with a similar setup, what PID settings worked for you? Would appreciate any advice you can throw my way!
Thanks a ton in advance

@mirellehgf something as simple as a silicon sock on the heater block can help , especially if your part cooling fan is blowing on it .

Tuning the heater as a tool rather than just a heater will help as it will integrate the cooling fan effect.
What command did you use to tune the heater and what was the result?

In what way does it fluctuate? If it is a regular oscillation then you can fix that by increasing the D parameter in the M307 command.
