X carriage hitting smooth idler

Hi there,

I just assembled my x-carve when running the homing test there was a loud clanking noise when moving towards the Y homing switch. After watching closely, it looks like it starts because the x-carriage is hitting the nut from the smooth idler. Im not sure what is going on, any feedback or suggestions would be appreciated. I feel that I am in way over my head assembling this

Hi Michael and welcome to the forum,
Your homing switch should contact the standoff and bolt before it hits the idler.
