@Alex-cr these are the ones
6PCS Optical Endstop Light Control Limit Switch for RAMPS 1.4 Board 3D Printers Parts with 3 Pin Cable Accessories https://a.co/d/123OLTbI will draw up a wiring diagram tomorrow

Please post your full config.g and your homing files.
Also the output of sending M122 and M98 P"config.g" -
@Adamfilip if they are compatible with RAMPS then they are designed for 5V. You can convert them to 3.3V if you identify the LED series resistor and solder a lower value resistor on top of it. See https://docs.duet3d.com/User_manual/Connecting_hardware/Sensors_endstops#h-33v-compatible-optical-endstop.

@dc42 the resistors on the sensor are so small and my skills with a soldering iron arent great. I dont think I would be able. to do. thats why I wondering where I can buy a 3.3v one ready to go. wish Duet made one TBH that was plug and play.

@Adamfilip here is my crude wiring diagram lol

@Adamfilip it is the resistor marked 181 that is too high a value for 3.3V. The good news is that you don't need to remove it (which is tricky), you can solder a 180 or 220 ohm resistor of the same size (probably 0603) on top of it, so that the two resistors are in parallel and make about 100 ohms.
Alternatively, if your Duet 2 is a sufficiently recent version, you can provide 5V power to those endstops as explained in the link that I posted.
5V endstops sometimes do work on 3.3V, so it's worth using M119 or the Object Model Viewer in DWC to test whether they are working.

@Herve_Smith 6 for $13 in US or 1 for $28 in Canada lol
-
@dc42 So if i manage to solder on a 220ohm resister like this. it should work.
-
@dc42 I can pickup some of these. but cant tell if they will work 3.3

@Adamfilip said in Optical Endstops:
Error: Unknown pin name 'e6stop'
Where is it actually connected?
-
@Phaedrux duex5 e6stop
-
Change your pin name to
duex.e6stophttps://docs.duet3d.com/Duet3D_hardware/Duet_2_family/DueX2_and_DueX5#pin-names
-
@Phaedrux Amazing thank you! that fixed it all. its all homing properly now. im shocked to be honest.
I am curious why you need to add duex before e6stop but not when declaring the drive number on duex with M584

@Adamfilip I use endstops that have an LM393 comparator chip and LED on board with Duet2 controller. They are very reliable and precise, except that I have had problems with them when sunlight hits them directly (an easy problem to fix, once you have figured out that that's the problem).
These are the exact ones I used, but they are no longer available.
These are similar to the ones I used.
The comparator slams the output either hard high or hard low, and it works fine with the voltage available at the pins on the controller board.
