Does your z-stop seems to have a mind of it's own? i find that every time i switch between abs/pla or adjust my print bed, or switch hotend, i have to re-adjust the z-stop over and over. It has become so tedious that i have to do something about it. And this is what i come up with.Print, clip-on and use.I only have short M3 springs, so i use 2 with a washer in between.
