Hey guys and gals! I'm very very new to 3D printing, and am trying to get my CR-10S set up with Octoprint. Have hit a snag though. 1.) I got the Octoprint image installed on my Pi. I can connect to it. I installed a TouchUI plugin, as my primary interface is an old smartphone I've dedicated to the print desk. 2.) I assemble my printer, connect the Pi, and connect Octoprint using the default serial settings. It works; I'm able to manually move all the axes through the Octoprint UI. 3.) Realizing I have no models on the Octopi yet, but wanting to use a test model, I grab the included SD card from Creality and plug it into the printer. (I found out later that this doesn't work - read on.) Seeing that it doesn't recognize the SD card, fiddling with settings, I start the "Init. SD" option on the CR-10S display. 4.) The machine stops and displays "KILLED." on the status portion of the display. I turn it off, unplugging the Pi, and turn it back on again, the error is cleared. 5.) However, now whenever I attempt to start the serial connection from Octoprint, the printer display "resets" (showing the Creality logo momentarily) and shows "KILLED." as soon as it comes back to the main status screen. Octoprint reports that the printer has errored and thus has disconnected. The printer still works - I can print from the SD card (now that I know it has to be inserted before starting up), just can't connect Octoprint anymore. Does anyone have any insight or notions about what might have gone wrong here? Thanks in advance!
