On your BOB can you identify which pair of inputs controls the e-stop - it should tell you where to look in the Mach3 configuration port and pins.
If you link a short wire across the e-stop pin and ground on the BOB and hit reset then you should be able to clear the e-stop temporarily (as a check). If this clears, then do not run the machine but instead remove the link and go and find the break in the e-stop cable runs.
Hi.
I've investigated the problem further today. Getting a parallel cable tomorrow to try that BUT I have noticed something else that I'm hoping someone can help me with.
On the G540 control unit, I have the red fault light illuminated but no power light. There is good power to the unit, resulting in no motor movements. Checked all cables and all seem fine. Any ideas please?
Best Regards,
Alan
