Always after having printed the 3rd layer in a print, the A1 pauses printing and the print head moves to the right, rear corner of the print bed (to an approximate position of x=255, y=250), makes a short motion in -y direction and then resumes printing.
Nothing appears to be wrong with that, but I’m curious what it is for.

Mine does the same thing and I was also curious. Doesn’t impact the print job but just weird.
My A1 did the same thing, even when I disabled the timelaps option.
The only thing I found to completly remove those weird moves was to remove everything in the “Time laps G-Code” in the parameters of my printer. Since I have done that, I have never had again those moves.

Im seeing this still happen in my prints even with nozzle clump detection disabled on the printer. Is there another setting, in the slicer maybe, that I need to tweak?
pretty sure it’s timelapse.
See if turning off Settings > Print Options > Nozzle Clumping Detection stops or reduces the frequency of your printer doing that.
Mine A1 mini does the same but actually it is making a mess sometimes as it doesn’t retract the filament properly and when it returns back, it messes the print with the leaked filament 
I haven’t found out how to disable it but I would like it to stop doing that as it is completely unnecessary and at most of the time it just messes up the print…
My new A1 with 150 hours of print time also did the same thing, but it was after the first layer. it went out of the dimensions of the print bed, lowered itself below the print bed, and then returned to normal printing like nothing ever happened.
Isn’t this similar to Lift Head in Cura? If the Minimum Layer Time is not met, the printhead will park itself a side for a short moment?
