End Stop problems

Mostly Printed CNC - MPCNC Troubleshooting
1

I’m brand new to this. I’ve been slowing putting together a Primo MPCNC, and this is my first major issue. I’m using Fluid NC on the Jackpot 3, a recent install of the yaml file from the Github.

I’m at the point where I have X Y Z movements working from my phone, and I should be able to start “squaring”, but when I push the home X button, it moves about 5mm in the wrong direction, then I get the error message “Homing Failed. Pull off travel failed to clear limit switch”. FWIW, the trucks are nowhere near the end stops when I get this message.

I did the $Limits test, and got these results:

No switch pressed:

X0 pressed:

X1 Pressed: (sorry, volume popped up, but it’s not hiding anything):

Photo of connections: Note, I have only connected the X switches at this point for troubleshooting:

Anything standing out there as the problem?

Nevermind, I figured it out, I somehow switched my X and Y wiring… I had taken all the wiring apart today to put the computer in the case and screwed it up … ooofff…
