Help! I just bought an Ender 3 Max. First time to ever 3D print. As far as I can tell it only prints gcode files from an SD card. I am using my iphone with an sd card reader. I can slice the models just fine with the cloud slicer, but then I cannot figure out how to get the gcode file?? It only lets me download an SLA file. When I click Print it only lets me pick options like blue tooth, raspberry pi, etc. How do I get the friggin gcode file created by the cloud slicer??
