Upgrading from Cura 4.12 to 5.6 no longer heats extruders or bed (sh.itjust.works)

Hi folks,

I've used Cura as my main slicer with my Flashforge Creator Pro for several years with no major issues. It was a while since I had upgraded (4.12) and I decided to try out the latest version (5.6).

My printer and slicing profiles seemed to transfer over automatically, but when I tried to slice and print, I encountered a strange issue: It no longer heats the extruders or the bed.

It just starts "printing" immediately with stone-cold extruders and bed. The temperature settings in my slicing profiles seem unchanged from 4.12, so I'm a bit at a loss as to what is happening.

I can verify that this is not a hardware issue with the printer, as I can run print jobs generated in Cura 4.12, and the heaters work just fine.

Anyone else encounter this or a similar issue? Any known fixes or recommended troubleshooting advice?

Thanks in advance!

What's in your start gcode ?
Maybe you use a variable that has been deprecated between the 4.12 and 5.6, and is set to 0 ?

https://all3dp.com/2/cura-start-gcode-end-gcode/

For example :
{print_temperature} Alias for material_print_temperature (deprecated, do not use)
{print_bed_temperature} Alias for material_bed_temperature (deprecated, do not use)

instead of :
{material_print_temperature_layer_0} and {material_bed_temperature_layer_0}

Thanks, this is my start gcode, which is unchanged between 4.12 and 5.6:

M140 S{material_bed_temperature, initial_extruder_nr} T0 ; set bed temperature
M134 T0 ; stabilize bed temperature
M104 S{material_print_temperature_layer_0, initial_extruder_nr} T{initial_extruder_nr} ; set left or right extruder temperature
M133 T{initial_extruder_nr} ; stabilize left or right extruder temperature

How up-to-date is the file on fieldofview? There doesn't seem to be any deprecated variables...
