Solidworks, saved as STL, opened in Cura 4.4.1, sliced and saved to SD card. I placed the car in the Ender but removed it to to check the code because I saw this happening to the OEM SD card the last time i used it. Its an issue with Cura, or maybe a virus from a downloaded model then slicing it in cure? Its defiantly happening in between Cura and the USB port though. Can custom slice settings cause this? The issue maybe started when i upgraded to 4.4.1 from 4.1.0 and i think i imported the settings over. Not sure i only use it once a month due to insufficient time to model parts but really need it to work when i do like any other tool. I'm trying to print a complete gauge cluster for a bus i have been converting to a motor-coach.
