When I send a Slic3r gcode file to print through Octoprint, the printer acts like its geometry is all wrong and will crash into the side limit. If I load the same gcode file on SD and print from there it's fine. Also noticed that when I download a file to the SD card using Octoprint it shows up in the Octoprint directory but isn't actually on the card if I remove it and check.
