Finishing pass losing position and

Hey guys I did my first 3d carve and the roughing pass went perfect however when I try to do the finishing pass it lost its spot and goes to the complete opposite side of the work area to start like instead of starting in the front left it goes to the back right and then when I try to home or jog it says the machine is locked out of nowhere… any suggestions on why this happened

What model cnc is this?
And during the bitt swap was the gantry moved by hand at all?

No I was very cautious not to move anything other than the tool when changed and it is a millright mega v xl i also just tried to run it on open builds with a similar outcome except for some reason in open builds it hit a limit switch

I am going to attempt it again today and video it if it does it again hopefully it was just a fluke or something I’m missing
