Endstop Maestro

[B3rserK]

Probably a stupid question, but being a rookie and be afraid to fry everything , I ask for an help.
I tried to look for an answer, but without success (or at least not a sure answer).
With this type of endstop (from a cr10), is my hypothesis correct?

Maestro - Endstop PCB

1. Y stop - V pin
2. 3.3v - S pin
3. GND - no pin
   and use "normally closed" setup

That board appears to have spaces for two resistors, a capacitor and an LED. But in the photo, it appears that they are not fitted. Is that correct?

If that's the case, pick whatever two pins of the connector correspond to the NC contacts of the switch, and connect those to the outer two pins of the 3-pin connector on the Duet. Do not connect the 3.3V (centre) pin on the Maestro endstop connector to anything, use the STOP and GND pins on the Maestro.

V is Voltage
S is Signal
G is ground

you can find out if its no or nc by connecting it and issuing M119

First of all, dc and veti, thank you for your interest for my stupid question
Board appears exactly like the photo, there are spaces but not fitted.

Weel i will try in that mode, it's correct?
Maestro Pins

1. STOP -
2. 3.3v - No pins
3. GND -

Connect 1-3 pins to "random" pins on pcb and try command M119 to understand if is NO or NC

Yes.

@dc42 Thank you i'll try

[dc42]

My guess is S and G.

Tryed!
Maestro - Endstop pcb
1 Stop - S
2 3.3 No pins
3 GND - V
launching M119 appears "not stopped"
clicking on endstop " at max stop"
