Syil X4 Plus - E-stop issue

[cropwell]

-Mach 3 doesn't see the e-stop as being pressed on the diagnostic screen - could this be the first place to fault find?

I presume that you have checked the port and pin used for e-stop. I would guess that the circuit is wired so that the normal operation is with the pin grounded. So a break in the circuit would force an e-stop. It also sounds as though the spindle relay is controlled by the e-stop. It looks like a previous owner has had a play with the wiring.

On the Mach3 diagnostics screen do any indicators change state when you operate the e-stop switch ?

Cheers,
