New error to the POS makerbot we have at our makerspace. Now it is hanging at "Position Found 77%" on desktop software with a "Waiting for File" "This May Take a Few Minutes" display on Makerbot screen. A few minutes might as well be forever because it never starts again. I have deleted Makerbot Desktop software and redownloaded most current version from website, I have performed factory reset on Makerbot. The error occurs with any model I try to print through Desktop, downloaded from Thingiverse or just a regular STL. The only print that works is the test prints like Mr. Jaws and Nut and Bolt from the Makerbot internal menu. I am not able to print from SD card either as the Makerbot cannot find any supported files on the USB stick. Grrr. Makerbot is so frustrating! Help?
