Thanks in hope!

I've converted a few of these A3HSR Routers and they usually have proximity switches for home switches. So it's my guess the Y switch isn't working.
I seem to recall it's located under the Z-axis cover and travels on the Y-axis and looks for a metal target at the end of travel but could be wrong as it's been a while.! . . . If I'm correct then Check the target hasn't moved or come off
