I've been using my X1C for only a week and loving it. But one thing I've noticed is that when I send my sliced model from the app to the printer it overwrites the last model on there previously. I appeared to work fine initially but now when I send a file to the last file used is replaced. I've made sure that I change the file name but if continues to happen. After I send the new file I click the file tab on the printer and the previously used print is replaced by what I have sent. Just wondering if anyone else has this problem. It's not a storage issue as the printer is still generating time lapses for every print and the card is 32g and definitely not full or even close.
