Not able to "activate" any material under material list in Cura, option is disabled.

[AmiSheiner 0]

Hi all,

I have Cura connected via USB to my Ultimaker 2 printer. everything seems to be working well, prints are coming out great, but for some odd reason, I cannot "activate" ANY material, built in or newly created in the settings\materials tab. Anyone knows the reason for this?

Thanks in advance!

For the UM2 UM2Go and UM2 Extended, materials are handled on the printer. The idea was that you slice once, and then have the liberty to print it with "any" material just by selecting a material on the printer. Because of this, Cura will not let you select materials, or temperatures.

If you want to use Cura to select materials and temperatures instead of the printer itself, go into Machine Settings (on the Printers tab), and change the gcode flavor to Reprap (Marlin/Sprinter). Then you get a materials dropdown in the sidebar, and you can edit temperatures, etc.
