Hi, thanks for your help. I realized I made a mistake. Simplify3D creates two output files after slicing - gcode and x3g. When I load the gcode into Octoprint I have the issue. When I load x3g into the QIDI 3D Printer, it works fine. The printer doesn't seem to accept gcode from the SD card and Octoprint doesn't seem to accept x3g. How can I fix Octoprint to either take x3g or print properly with my gcode?
