Yeah I already have an Ender 3 modded with linear rails and a Hemera, and have both added in Cura and running off one Octopi Being a bedslinger tho, the Ender3 does not compare to the new CoreXY IDEX. I have souped the Ender 3 speeds up to the max (100mm/s, 3000 accel), but this new one will do 200mm/s, 6000 accel out of the box without any tweaks. Plus of course it's an IDEX, so I can use Copy Mode to print off two copies at once, making it basically 4x as fast as the Ender3 My printer does not support those AFAIK. Besides, this preheat issue mainly concerns "Normal" IDEX mode (Multi-material in one print) I put in a feature request on the GitHub repo, let's see what the devs think...

I have just got my first IDEX printer (Snapmaker J1) The Cura profile which comes with it does not start heating T1 until both T0 and the bed have heated up Here is their start g-code: ;--- Start G-code Begin --- M104 S{material_print_temperature_layer_0} ;Set Hotend Temperature M140 S{material_bed_temperature_layer_0} ;Set Bed Temperature G28 ;Home G1 Z0.8 M109 S{material_print_temperature_layer_0} M190 S{material_bed_temperature_layer_0} G1 Z0.8 F6000 M201 X10000 Y10000 Z500 E5000 M593 P1 F50 M205 V5 G92 E0 G1 F200 E2 G92 E0 ;--- Start G-code End --- If I change it to this: ;--- Start G-code Begin --- M104 S{material_print_temperature_layer_0} ;Set Hotend Temperature M140 S{material_bed_temperature_layer_0} ;Set Bed Temperature ; >>> MODIFIED CODE START M104 S{material_standby_temperature, 1} T1 ; Start heating T1 ; >>> MODIFIED CODE END G28 ;Home G1 Z0.8 M109 S{material_print_temperature_layer_0} M190 S{material_bed_temperature_layer_0} G1 Z0.8 F6000 M201 X10000 Y10000 Z500 E5000 M593 P1 F50 M205 V5 G92 E0 G1 F200 E2 G92 E0 ;--- Start G-code End --- then this seems to do the trick, but there's a problem: If I do a single extruder print, and uncheck "Enabled" for the 2nd extruder, like so: Then the generated G-Code still heats the 2nd extruder, even though it is not used for the print. Is there a way to somehow generate conditional G-Code, or is there some equivalent of {material_standby_temperature, 1} which would return 0 if the 2nd extruder is not used?
