Switching from servo/microswitch ABL to prox probe, need help

[Roxy]

I just want to know, if it is more accurate and repeatable than servo/microswitch.

Just to be clear... I don't know the answer. There has been a lot of good success stories about using inductive probes but they always seem to be associated with very high dollar parts. Not a $5.95 part from eBay.

By the way Roxy, what type of microswitch do you use? Do you use one with a roller at the end of it? How long an arm should I go on the switch? What is the most repeatable switch? I guess I am asking.

But what I do know for sure is even the cheapest micro-switch from China bought off of eBay will produce very good results if the rest of your mechanics are good. I am using almost the cheapest one possible. It looks like this:

And I can get .002 mm repeat-ability every time. Given I usually print with .28 mm layers, the micro-switch isn't the source of any problems I hit.
