I found a workaround by accident. If your startup gcode contains no reference to any print temperatures (no {material_print_temperature} variants, even in a comment), Cura will automatically prepend the gcode M104 S{material_print_temperature_layer_0} M109 S{material_print_temperature_layer_0} before your startup code, with the correct temperatures. This is going to wait for the nozzle to get fully up to temperature before doing anything else (including heating the bed) so it might not be the best solution. /Frank

I had the same problem. It's a regression bug in Cura 3.1, and is supposed to be fixed in 3.2. As a workaround, you could just change your startup gcode to S230 for now, then change it back whenever 3.2 comes out. Not ideal, but at least you won't have to edit every gcode file. /Frank

Now I see it, issue #1296. Thanks!

I'm trying to print using the ABS/Fine profile, using Cura 3.1.0. The profile has Default Printing Temperature: 230 Printing Temperature: 230 Printing Temperature Initial Layer: 230 Initial Printing Temperature: 220 I have a custom printer defined, and my startup gcode contains the following line (I put all the temperatures I could think of in the comment just to see what they were): M109 S{material_print_temperature_layer_0} T0; {material_print_temperature} {material_print_temperature_layer_0} {material_initial_print_temperature} When I generate the GCode, it results in: M109 S210 T0; 210 210 200 These don't match my settings. Changing any of the temperatures has no effect on this line - it's always the same. Only the material temperatures are affected - {material_bed_temperature} and {material_bed_temperature_layer_0} follow the settings as expected. Am I missing a setting somewhere, or is this a bug? If so, any idea of a workaround besides defining a new printer with the temperatures hardcoded? Thanks, /Frank
