Z-limit switch set too low, and then winding the bed down onto the springs to compensate.I am still struggling to figure out how your bed can be fouling the y-axis servo. Mine comes nowhere near.

It depends what bed you're using. If you use a glass or similar thickness bed, you have to move the limit switch up from the stop, otherwise you could get the problem of the bed catching the rear stepper.The switch mount has a stop on it to prevent that. If you managed to mount it that low you would know that it was because you cut the stop lug off.
Are you levelling the bed when it is hot? Could be warping slightly when hot.It seems that we are back to the bed level variations again. Even with the BL Touch it's not right. I did a quick ABS print using the settings from the Benchy and found that the rear / left portion of the skirt wouldn't print, even though it is set to four lines. I re-levelled to find that it was again well out, so I spent some time getting it just so again. The subsequent print showed exactly the same issue. The same part of the completed print released with a strange white stain underneath. Most likely the 3DLAC I would guess.

Incidentally, the reason that I had to reprint this part is because the PLA version warped in the car over last week's warm weather. This one is ABS. I also now have some PETg transparent to remake the lens.
I have a Borosilicate bed and always level stinging hot, so at working temperature. I will have to spend some time going through it again. Luckily that print is usable.Are you levelling the bed when it is hot? Could be warping slightly when hot.
I found going to a glass bed sorted most if my levelling issues (ally bed was bowed)...
