SKR 3 EZ and wire limits question.

[Demitrius]

Hello Jon,

I found limits wire scheme, with resistors and capacitor.

Scheme attached.

What do you think, need wire same for SKR 3 EZ?

In my build, I can connect 2 limits (start and end stops) to X-axis limit port, cable length about 3 meters. May be better to add capacitor/resister?

Looking at the schematic, they already have the onboard resistors and capacitors for the limit switches.

Ideally all the inputs would come through optocouplers for added protection, but I suppose it's a 3D printer board after all.. :shrug:

Completely agree, the optocouplers is definitely overhead. I will do it as it is, without extra elements.

Jon, thanks for help. I appreciate it.
