I already reformatted it and same thing happens. I bought 2 more sd cards and I have the same issue. Sucks that customer service responds once a day :/
Kind of frustrated now with my boss forking up the budget to buy one and not being able to print my 3d models.
I've done factory reset multiple times but I think somehow something might be wrong with software? All I have done when I opened and set up was do the platform calibration and that's it. Not sure if I had to do anything else. By the way I am using windows 7 if that makes any difference?
