MACH4 not responding to Y Axis Homing Switch
« on: February 10, 2025, 09:10:52 PM »
Hey all!

hoping someone can help me figure this out:

I recently installed Mach4 after having motor issues with a Pokeys controller and Mach3 (wouldn't slave the A-Axis with the Y-Axis).

Most everything during configuration went well, but I seem to be stuck with getting my y-axis home switch to be seen by Mach4.

I've used the Pokeys diagnostic routine, and it sees the activation of the Y home trip.  I can also see that Y-home activates, but never once do I see an event message as such.

I started logging and I do see an event of the Y Home, however, it seems like its missing an additional Signal id result, though that may just be me hoping for something easy.

i've tried to swap the X and Y home switches by changing the ports, and the problem stayed with the Mach Y-home and the physical switch in question worked fine as a X-Home.

needless to say, when I try to home the machine it just trips the limit switch and ignores the home.

Not sure what to try next...any thoughts?

Thanks

I think your Y home switch is not properly mapped in the Input Signals settings. Double-check that Y Home is enabled and assigned to the correct input (Signal ID 66 or your Pokeys pin) in Configure -> Control -> Input Signals.
