@hairy_kiwi:
Additionally, I just tried cancelling a print (with bed at set temp, extruder almost at set temp) and restarting the same print only to discover another problem: the extruder temperature is never re-set to printing temperature - the extruder head moves but cold extrusion protection is apparently kicking in to prevent extrusion. This probably needs more testing and verification, but will need to wait a week until I can play again.
That would be because you started the new print with no tool selected, and you didn't have a T0 or other tool selection command in your start gcode in the file you printed.
