End Stop Wiring
-
Can someone help me with how this should be wired to the Duet Wifi. Not sure the pinouts are correct.

this might help as i am doing the same thing now. i noticed the pins are labeled on the sensor. nc= normal closed and no is normal open and common

The complication is the LED. The Duet has an LED attached to the endstop input too, and if you wire it that endstop board incorrectly, you may get a situation in which the endstop doesn;t reliably show as triggered or not triggered in one of the states.
Are the connector pin numbers not marked on the board? Can you give me a link to the schematic for that board?
At a guess, The red wire goes to +3.3V, the black wire to Gnd, and the green wire to STP on the endstop connector.

Hi, i have this endstop too
I can't understand if it is an active-high output (NC) switch or an active-low output (NO)…
If in the config.g i set it wrong, can i damage the board? Or only they don't work good?
Thanks in advance -
Cant hurt the board by having active high/active low set wrong.
If unsure, just test using M119 in the g-code console.

If it's a Makerbot endstop switch or a clone of it, this is now documented at https://duet3d.com/wiki/Connecting_endstop_switches#Makerbot_Mechanical_Endstop_v1.2.
