You'll probably want to run a pid tune if you go from using a sock to bare heatblock- it's a relatively large surface area that just became a whole lot more thermally conductive and the pid coefficients didn't account for that.
Hmmm I'm still rocking my ender3 I have to check if I even have that setting.
It's an option in Klipper however unsure if it's available for Marlin based printers. My V3 SE didn't have it from memory - now running Klipper both bed and hotend tuned finding the temps don't bounce as much.
For your issue not sure if a tune in this regard would resolve your issues, strange issue to be seeing.
PID tuning is available in Marlin printers. I've had PID tuning in my 6 year old Prusa Mk3s for 6 years now. Whether or not it's been turned on for that Ender 3 is another question. But it can be turned on with a bit of editing.
Bambu though, has seen fit to remove manual PID tuning for users. I'm not impressed by that. A step backwards IMO.
Sounds like something Bambu would do, considering their recent drama. Really are trying to be the iPhone of the 3D printer market.
I've only been printing since Novemberish and hated how locked-down the Marlin firmware was on my V3 SE (compared to Klipper), I upgraded my nozzle and needed to flash the firmware for temps up-to 300c so it was use a modded Marlin or flash Klipper.
Bambu hasn't been the first to not turn on some features in the standard Marlin firmware. They won't be the last either. PID tuning isn't something you do a lot of anyway. Maybe once or twice if you change out extruder types or do a complete reset of firmware. They are probably calling some kind of macro to automatically do it for all the newbies out there. If you went and studied Bambu's firmware, you could find the section in the firmware to turn it on I suppose.
Oh, I'm more having a jab at Bambu attempting to raise their walled garden via their latest firmware.
Yeah it's the way of the world, I'm very glad my printer has a community supported Klipper firmware - and am glad to see some people working on this for the folks in the Bambu camp too.
Lots of people out there that don't want to be bothered but such details. And absolutely don't want to spend time learning the why you do something.
Oh but it's like anything in life, you can skirt the brim and get a taste of what's on the outside of the bowl, or you can run down the sides and take a splash with the real meat and potatoes.
Nothing wrong with not asking the how or the why, or the who and the what however I find that attitude has led us to being between three and twenty five foot tall, made of a hairy, oily goo wrapped in a tee shirt.
