I used Cura to update my Sigma’s firmware to 1.2.0 and installed the corresponding LCD files in the LCD’s microSD card (properly formatted as FAT-16), but now my printer won’t boot pass the BCN3D logo! The logo appears on the screen very slowly and then stays on. The version number on the bottom right shows 1.2.0, but it won’t pass that stage. Does anyone have an idea of what could be going on? my printer is bricked!
