When they should be at 215 and 105 respectively.  If i hold a lighter to the extruder it goes right up in temperature so its not a thermoresister problem.  And the fact that both the bed and extruder are having the issue makes me think there is a deeper problem.  Any help would be great....im running out of stuff to fix.

p.s. the hot ends only a few months old. Also if i disconnect the software from the printer then re connect they start to heat up fine but will eventuallf fall and send the print job into error.
