Issues with my 3D prints
Looks like insufficient cooling. If it only just started, your part cooling fan might be clogged with dust and debris, or have a failing bearing making it spin slow and give low flow, or might have ...

Most probably this is caused by an adhesion problem. When the first layer doesn't stick well enough, this could be related to wrong bed temperature, incorrect distance between nozzle and bed, ...

How do I fix deformities when printing on my Ender 3 V2?
Update: I identified the issue as a lack of tension in the X and Y timing belts. After tightening the belts, the prints are much smoother !

Why does my print have this unusual pattern?
Layer height should be max. 3/4 of the nozzle width, so you should print at max. 0.15 mm layer height with a 0.2 mm nozzle. So the problem is that you are using a too large of a layer height (0.2 mm). ...

Travel path line appeared and I can't make it disappear
The line in question is a travel line, so no extrusion is deliberately done there. So, if you see that filament is being deposited, your retraction settings are incorrect.
Generally, a blob is ...

What do you call this effect in 3D printing and how can I remove it?
Your retraction-related setting "Extra Restart Distance" = 0.12 mm could be the cause of your issue, by using a too-high value.
I don't know which slicer you use, but it seems that this ...

Why is the bottom of my part not smooth
In my case, the build plate adhesion type was set to raft in the cura software settings which is why a base will be printed first before printing the object on it. Hence, the bottom of the printed ...

What are these effects caused by? And can I get rid of them?
Are you using Cura? If so, this is almost surely combing, where it performs travel moves across already-printed material without retracting in order to avoid the time cost of retraction and work ...

Do bevelled corners hold any practical advantages or disadvantages over square ones for blocky functional prints?
Bevel chamfer fillet, whatever. For correct semantics see the other excellent answer.
What are advantages of rounded (or at least, less sharp) edges and corners?
In FDM, curved xy paths are stronger ...

Do bevelled corners hold any practical advantages or disadvantages over square ones for blocky functional prints?
Will bevelling the corners for purely aesthetic reasons have any practical effect on the print or the printing process.
No, not necessarily in this model. If one positive reason for using a chamfer1) ...

Printing with 1 mm nozzle keeps failing
A cursory inspection of your settings shows that you are printing at 75 mm/s and 210 ℃.
If you were printing with a 0.4 mm nozzle and a 0.2 mm layer height, the flow rate will be 75 x 0.4 x 0.2 = 6 ...

When gaps happen on the first layer of the print, this is caused by the first layer Z being too high, so that the extrusion is not being properly flattened between the build plate and the nozzle. (If ...
