No start signal detected-forcing start ?


I got this message on Repetier host :
'no start signal detected-forcing start'

I can not detect my bed heater and extruder heater, and I can not control my motor, it happened suddenly,
I can connect to my printer, but my printer LCD frezzed on Welcome message only, I can not got to its menu....

What happened here ?

Any clues ?


  • LCD is independent of host communication, so it is a crash in the printer preventing connection. Try reflashing firmware and see if it is gone. Sometimes flash changes value causes crashed not present before. Since it worked before it might be that.
