Y1 servor motor is in error (fixed, loose wire)

[Kevlar (Thomas)]

Hello,

When I turned the machine on today, the Y1 servo-motor red led was flickering on and off.

I unscrewed the cover to see if the wires were all good. When touching the wires it seems to make the alarm go away for a second or two before going back to error.

I tried to re-seat the green plugs. Then when I turn the machine on again the Y1 red light is on for good now.

I don’t know what to do ?
Any suggestions ?

thanks.

Ok I have found the culprit :

the green wire jumper had a faulty contact.
Now it’s working fine. See picture attached
