Same error on Cura 4.11.0 but does not reproduce o n other printer e.g. Anycubic 4Max

I confirm the problem for both Build Plate and Printing Temperatures. GCode generated doesn't take into account values for Initial Layer. Here on an Snapmaker 250, Normal profile. Cura 4.12.0

In the Snapmaker2.def.json file (which appears to have been written by someone at Snapmaker) the startup gcode is defined that way and neither the A250 nor the A350 specific definitions override it. M104 S{material_print_temperature} ;Set Hotend Temperature M140 S{material_bed_temperature} ;Set Bed Temperature and later: M109 S{material_print_temperature} ;Wait for Hotend Temperature M190 S{material_bed_temperature} ;Wait for Bed Temperature

Those keywords need to be "material_print_temperature_layer_0" and "material_bed_temperature_layer_0". You can alter them in your StartUp G-Code. You should probably let Snapmaker know as well so they can alter their definition file.

Thanks @GregValiant that has fixed the issue and I'll log a support request with Snapmaker.

Please unclose/reopen this issue and we (at least you and I but probably more) can get more traction on the actual fix in cura rather than hand editting settings files...

@tyeth, the problem isn't in Cura. The problem is in the definition file that Snapmaker (or a Snapmaker user in the "community") provided to Ultimaker.

The issue should be fixed by #10849 now.
