Printing.. but extruder cools down

Almost there..
Everything seem to work in manual mode (dry run).
To heat the extruder, I acivated dry run and send command M302 S1. Extruder worked as expacted.
However, when I start the print job, head started  to move as if it's printing but extruder doesn't do anything and heater cools down (while host indicated it is being heated!)
What am I doing wrong?
I tried to disable dry run, but the problem remains.


  • Would M111 help here?
  • M111 is the command to set/disable dry run. Make sure you disabled dry run before starting the print or it will ignore the heat commands.
