I had a timeout it seems on Repetier Server and when it continued it didnt resume properly:

As you can see from the logs it isnt setting the temperature:

Recv:7:19:45.600: T:204.46 /0.00 B:53.86 /0.00 @:0 B@:0
As such after a while it fails due to:
Recv:7:20:38.246: echo: cold extrusion prevented
I assume my pi restarted or the server restarted but tbh idve rather it abandon the job than continue and waste filament and not tell me so that I can fix it.
