Homing Y/A Axis Says Limit Switch Triggered

[Stevenson]

It’s difficult to describe what you ask Neale because when I click a switch I can’t take a snip so I made the attached sketch. The black cells mark from the top down the lights ON in the indicated axis on the left of each bank.

But in my notes I found that M1=X, M2=Y, M3=Z and so I don’t understand why when I reference the Y I get on the diagnostic screen the M4 lights as shown but only for a few seconds and then I get the message “Limit switch triggered…”

I also switched to ESS because it’s difficult if not impossible to find a PC today with a parallel port and besides where can I find XP or Vista to run the PC?

Thank you
