$5 Endstop Inverting Issues about sam3x8e HOT 5 CLOSED

Each one just triggers Y, should they not be Y & Y1?

If in the realtime report then only a single state for each axis is shown, all limit inputs are combined for that. If you want to check status for the individual limit inputs use the $lim command.

With $5=7 what are the voltages on the limit inputs when none are triggered?

Thanks for the quick reply, that's good to know about the $lim command.

I tested all of the inputs electrically, they each output 3.3v when triggered. I am using a level shifter as the sensors need 5v to function.

It's strange because they all trigger at some point with a variation of $5 = 1-7 but do not invert as expected.

This is the result of actuating the endstops and the result of $lim

$lim
X Actuated - [LIMITS:Y,Z,Y,]
Y1 Actuated - [LIMITS:XY,Z,,]
Y2 Actuated - [LIMITS:X,Z,Y,]
Z Actuated - [LIMITS:XY,,Y,]
Nothing Actuated - [LIMITS:XY,Z,Y,]

This is with $5 = 7

And with $5=0?
It looks like your switches are wired as NC. Since this board has max inputs (for X and Z) the unused inputs should be grounded so that they do not mess up the combined state.
BTW I am currently away and do not have access to boards with max inputs so cannot check myself before I am back (next month).

Thanks for the tip, grounding the unused inputs did the trick! Thank you for your help!
