Velocity painting has been around for years but never integrated into a mainstream easy to use platform. I like the subtly of velocity painting a bit more, but regardless, I hope to see better slicer integration of some sort of surface painting feature soon.

Interesting that this affects the gcode rather than the model itself. I wonder how this would compare to just sculpting surface details in something like blender
Much lighter files and faster slicing, I imagine.
It's a neat idea, similar to how displacement maps affect the output without affecting the geometry of a 3D render.
Also, I like this image, as it makes me feel less bad about my own grizzly-looking heat block.
I use a silicone nozzle cover to hide my shame.
My printer freaks out and squeals if I don't use one.
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.
