New to simplify. I added a model into simplify3d, processed it, and used the save toolpaths to disk feature -- with the goal being to put the file on a USB drive and then to print it via my Qiditech x-pro's usb port. That said, when I open the file within my printers interface, I do not get a preview file. Also, the print itself never begins to preheat, print, or perform any type of process. I have tried this with a few models and with both dual and single extrusion and seemt o get the same result everytime -- my guess is though of course, that I am doing something wrong on my end.
