Hotend PID tuning method?

[Blackavid]

Hi all! After years there is still not PID Autotune working as it seems. My printer doesn’t give anything back and I can’t read the values.

In this thread here I discussed the problems with my inconsistencies and I only found the reason to be the fluctuating temperature which was jumping up and down 4deg around the setting point (197-202deg)

Inconsistent Layerlines

Hi all! So yes the feeder is clean so far. I also suspected the Wear of the feeder wheel but for me it seems to grip enough. What I suspect is the temperature swinging around the set point for ±2deg. Support tells me that it is totally normal. I put some thermal paste into the heat blocks hole for the heating cartridge, Sensor is properly attached, nozzle is a Phaetus Tungsten 0.4mm nozzle but the problem occurs also with other hotends. Sadly I can’t modify the PID values or run an autotune. …

Now from this thread I took the D106.25 value from FW 1.12.2 saved them into the EPROM. E voila- the Benchy looks way more consistent. It takes longer to reach the exact temp of lets say 210- it comes to 209, stays for some minutes and then gradually hops to 210 until it almost stays there the whole time

For me this is the reason to say: WE NEED PID AUTOTUNE
