Hello,

I purchased CTC 3D printer a week ago and so far I have been satisfied with print quality. However it doesn’t seem to be able to read SD cards (it detects the card but doesn’t find any files). I figured that I have to update the firmware from 7.4 to newer versions but I don’t know which MCU is inside the printer (maybe atmega2560?). Any of you know how to open the CTC printer to see the MCU board without disassembling the whole thing? I have similar ctc printer as in the image
