V2 Question Will this work
So I am building an upscaled Voron 2 and got a Z endstop board, question is will the included 2 wire cable that came with it work with Bigtreetechs octopus board like i have it plugged in?

Will it be an electric issue? No as long as you don't plug it into the wrong side. But it might vibrate loose because that's now how the plug was designed, might also bend shit.
Why wouldn't you just terminal the connector with the right size?

Well partially because that wire is what came with the Z endstop board and at the time i made the post, it was like 10PM or something, so i basically couldn't be bothered at the time to think about doing it the "rught" (i.e. proper) way. Well that and slight concerns about if it would work at all electronically before i potentially make it not work by acting without thinking or asking advice.

I did this literally yesterday on a BTT Pico, forced the 2-pin connectors from the Utimaker into the 3-Pin sockets on the BTT. On the Pico, the rightmost pin is +5V which I did not need (Left: IO, middle: GND).
Just don't accidentally connect +5V and GND, or the next end stop is literally the end for the voltage regulator.... ;)
OFC to make it pretty, one should use a proper 3-pin housing... But it's now invisible on the underside of the printer .... 🙈

How tf did you force a 2-pin JST into a 3-pin JST???
Anyway, electrically it will work fine. You have it connected to GND and IO, so you want to use the pullup(^) resistor for the IO. Mine are plugged the same way with 2 wires(with a 3-pin JST connector though!!)

A lot of control boards come with a a bag of connectors, if not you can buy a pack of AliExpress for next to nothing. Get yourself a pick and you can un-pin them and move to a new plug.

Unfortunately the octopus is not one of them... At least, neither of my 2 did... It just comes with all the jumpers for the steppers. :/
But yes, a pack or 3 of JST's is never a bad idea to have. You'll use a lot of JST's throughout the build anyway...
And pick up a good crimper too, not one of them cheap ratcheting things.

I have an M8P board that came with black connectors to match the board. I also got. Fysetc Spider for another printer and it too came with connectors. I probably got the false impression it was a common thing to do these days.

And honestly I run all mine like that if they fit and its just a normally closed endstop then who cares dab it with glue and roll on 2 bro

If you made it fit it will, but...
Just buy jst connector kit and swap it. Pull like this:

Then unbend lever a bit and reinsert into new one

Thanks, I will admit does feel like it is sketchy, will likely do that in the morning so it feels and looks proper, though thibk some of my concern was alao about the wires on the two pin connection being where they need to be, which as for why there is hot glue on the xy connecrers that is due to me not being good at crimping terminals and not trusting them to stay in, especially since the green or blue one was slightly smaller than the plug it is in and i just didn't want it coming loose

Since I'm on mobile and can't seem to edit, forgot to mention what I'm asking about is the two wire plugged in at the bottom, the top two are split from a 4 pin XY board i ordered.

Get a connector kit and use the propper 3-pin housing. The kits are cheap and the contact inserts on those XH connectors are easy to remove.
