Extruder went cold after pause
Today I tried Pause/Resume for the first time.
The Pause went as expected.. But I almost immediately selected 'resume' and got the message "Heating......".. But whilst the bed stayed at 60/60, the extruder went to 200/0 and decreased continuously.
I tried to pause/resume a few more times, but it seems to see if I could trigger the extruder into life, but nothing happened, so I had to "stop" the job.
This stinks of a bug.. are there any known issues with Pause/Resume? (I am on the latest firmware by the way 3.3.1)

Jon,
I've experienced this twice with the Pause/Resume feature (but not every time).
I worked around it by manually setting the nozzle temperature (LCD Menu - Settings - Temperature - Nozzle). I don't think you need to cancel the print when it occurs.

You're not alone. Github issue is already placed:

I had this issue once. Had to set the temperature manually Tune-> ... and it worked fine. So the workaround does work, no need to cancel the print.

Re: Extruder went cold after pause
I had to use pause today for a genuine reason. And again, resume didnt switch the heater back on.. but ss you pointed out, manually setting the temperautre worked perfectly.
