Ender 3 v2 Cura Profiles - Anyone willing to help/share?
Use the profile for any Ender 3 model, or better yet just start from scratch and put in the important properties that actually vary per machine - bed size, temperatures needed, etc.
Cura profiles for specific printers, especially the ones Youtubers are promoting, are almost always misguided if not outright wrong. They're a mix something like 5-10% settings that are actually physical characteristics of the machine, and another 5-10% dubious settings that are tradeoffs that might help avoid common problems for the machine at the expense of making other (often worse) problems, and the remaining 80-90% personal preferences of the person who made the profile. For instance, looking at Cura's base Creality profile:

Machine max accelerations are all wrong, at 500 mm/s². The machine can actually handle at least 3000 mm/s², and unless you've updated firmware to have Linear Advance, increasing acceleration is the only way to avoid inconsistent extrusion.

Z speed limit and acceleration are very low. This makes seam more severe and has no benefit.

Print speeds are random and differ per type (outer wall, inner wall, skin, infill, etc.) which doesn't work right on a bowden machine without Linear Advance firmware.

Z seam type is overridden. This is purely personal preference and has nothing to do with the type of printer.

Gaps filling settings are overridden. Same issue.

Retraction settings are botched, especially increase of window for max retraction count from 4.5 mm (default) to 10 mm, which will cause severe omission of retractions (thus stringing, oozing, and failed adhesion) in any print with thin layers and fine detail.

Enabling skirt. This is purely preference.

Lots of support settings. What's needed here is 90% of a function of the object you're printing and 10% a function of your machine's properties and there's no indication that the settings in the profile have anything to do with properties of Creality machines.


Etc. etc. etc. Most of the above dubious/wrong stuff was added fairly recently in Cura, taken from the &quot;Creawsome&quot; profile popular on Youtube and Reddit. Before that they had a more minimal profile that at least wasn't wrong.
The actual properties you need to set in the profile for your particular machine are:

Bed size/print volume
Heated bed
Filament diameter
Nozzle size
Retraction length (depends on hotend and extruder type, bowden tube length if bowden)
Retraction speeds (depends on extruder capability &amp; friction in path, etc.)
Fan speeds (depends on how powerful your fan is)

Setting max speeds and accelerations is also useful to get more accurate print time predictions, but not necessary.
