Settings visibility and actual visible settings do not match

I am trying to change print temperature in Cura 4.12.1, for my Ultimaker 2+.

The option is not in "Material", although it is selected for visibility:

 

What could possibly be the problem?

 

If I search for "temp", the Material menu shows up, but expands to nothing.

    This is "by design". For the Ultimaker 2 family, you set the material on the printer, so the printer sets the temperatures. Also note the small exclamation marks in front of the checkbox. They have a tooltip.

     

    If you would rather control everything from Cura, go to the Printers pane of the preferences, click the Machine Settings, and change the G-code flavour from "Ultimaker 2" to "Marlin". Personally I think that is the better workflow.

    Thanks for the reply. 

     

    You mean that selecting the material on the printer upon inserting it, is what is meant to set temperature? But what if you have two brands of PLA, which you want to print at different temperatures?

     

    I suppose selecting "Marlin" implies that I need to flash the firmware of the printer?

    One of the problematic assumptions the Ultimaker 2 was based upon is that all PLA prints the same, and the only difference between PLA and ABS is the temperature. The benefit was that you could slice once, and then print with whatever material you happen to have loaded on your printer. It was later realised that this does not really work, because you also need different speeds, different buildplate adhesion and different supports etc.

    No, it only means that temperatures are fully controlled by Cura and specified in the gcode, instead of the printer inserting the temperatures on the fly. You don't have to change a thing on your printer, but your printer may tell you that the gcode file you are printing "overrides" whatever temperatures it thinks you want to use (which is exactly what you want).

    I can put the temperature in the Material Profile instead!

    That might work. Or not. I am not 100% sure. It may work when you create custom materials.

    Wait a minute. If I DON'T change to Marlin flavor gcode in Cura, but still insert M104 commands into the gcode (post-processing gcode, I'm printing a temp tower), will the printer override these temperature changes? So my additions to the gcode do nothing?

     

    I mean, the temp tower I got is pretty much the same for all temps...

    AFAIK, the printer adds its own M104 command before it executes your gcode, so any M104 commands you add should work, even with "Ultimaker 2" gcode flavor. But to be honest, I've always just set the gcode flavor to "Marlin" (since that also allows printing over USB through OctoPrint, which for me is the better workflow).
