[Solved] Printing Temperature Initial Layer not working

[bassamanator 1]

No matter what I do, I can't get the first layer to print at the specified temperature, 270C in this case. If I set Printing Temperature to 270C, it prints at 270C throughout the print. I've also tried setting Initial Printing Temperature to 270C at the same time also and that doesn't work either.

 

What gives? Using Cura 4.10.1.

 

Thanks!

Different placeholders in the start script are required to achieve this.

 

Try to replace:

 

{material_bed_temperature}  ==> {material_bed_temperature_layer_0}

{material_print_temperature} ==> {material_print_temperature_layer_0}

 

or {material_print_temperature_layer_0, 0} if this is a printer with more than one extruder.

What about the rest of the layers? How would I change the startup gcode so that it changes the temperature for layers 2 on wards to the default print temperature?

@tinkergnome that worked. Thanks!
