Error in filament change script?
I just wanted to change the filament but instead of stopping, the printer kept moving while it turned off the hotend heating. I just realised it when it had continued about two layers. I assume that this is not the normal behaviour, but maybe a bug?
Hard to say with no exact description. Could also be firmware having disabled heaters without server knowing that. If server pauses you can tell it to disable heater after x seconds. In that case first continue is preheating and second continues print. Can also be some commands in your continue print script.
I'll take a closer look into this. As soon as the next spool is getting empty.
