I notice in the Cura software when it writes the gcode file it does not set the material tempature to the material selected in the library. Its always processes the tempature to 190 degrees no mater what material I have selected. The Manage Materials selection in Cura 2.3.1 does not work in windows, I read that there was a known problem with Manage Materials in the older versions but it was stated to be fixed in the newer version which it is not. My fix is to manual edit the gcode file and input my desired tempature. Anyone have any other suggestions?
