Hi, I'm working with the repeater host, and want to operate without connecting my computer to the printer, I want to upload my designs to an SD card which will connect after to the computer. I want to change the print, printer and filament setting of the slic3r that comes with the program. The problem his that wen I open the slic3r tab it does not allow me to change anything. There's drop down menus for each category but noting happens when I click them, even when I click configure at the top right corner nothing happens.
