Beyond checking all of your connections, no - but I've had my power leads come loose...
Is everything else ok? Head moves, etc? You get heat to the head?

thanks for the reply, i got the hotend extruder red light to come on [with affirmative connected log report] but when i turned the bed on: the power supply shut down/ no fan but restarted fine! but no red lights back on ,this after changing around the 0 1 values in theEprom config firmware for extruder heat manager?

But your EEProm is activated ...
So that might not do anything anyway.
No clue after a shutdown. Let's hope some other chime in...

Sounds like you tripped a protective function in the power supply. I'm hesitant to suggest something other than double check your wires again. I say that since it'd be easy to see if it happen if you just heat the bed without the hotend on (if it works without the hotend on it suggests the powersupply might have been overloaded, if it shuts down again it could still be the power supply was overloaded or something happened to the wiring or something else), but it's not good to rely on protective functions like that when trouble shooting if you're not ready for magic smoke release to point out the problem.
