So for my next printer build I am going to build a delta of my design. I am trying to get the best possible quality out of it and therefore I feel that I need to make sure that every aspect had been engineered properly.

My question is that for the three endstops at the top, would optical endstops play an advantage over mechanical? From my understanding optical endstops are more accurate but I am not 100% sure. I will most likely still be using an inductive sensor to autolevel the bed as well.

Thanks!

i’m not certain but i think if auto leveling is used, endstop accuracy does not matter.

I disagree. Auto leveling is for the bed inaccuracies but endstops are for effector positioning. You could perfectly level the bed but if your endstops are wrong - you won’t get a good print.

Optical provides some advantage over mechanical because there is no wear.

Definitely go optical if nothing else matters.

I am using mechanical endstops but with short throw microswitches. The firmware is such that the carriages will travel up reasonably fast until the endstops are activated, back off, then slowly go back up and activate them again. The speed at which the second activation happens certainly improves accuracy.

I have heard some people say that optical can fail if there is some light point near

I think the little hall switches are smallest easiest and cheapest.
