I did some research and I found out when I slice with Simplyfi3D and save the G-code on the external SD card all is fine.In Flashprint the same crashes when I sent the G-code via usb.So when I sent G-code via usb the file would be stored on the internal TF card and I think that is the problem.Maybe a corrupt TF-Card?


What is the TF card? (SD Card?) Does Flashprint store the print on the SD card for USB printing? I've never used printing over USB as it was extremely unreliable for me. I've also read many other people having problems with it at various times, without any 'rhyme or reason'. I suspect you have a problem with the USB communications, either in the printer, computer or USB cable..?
