Has anyone received any response or resolution to this issue? Is the only solution to replace the main board?

I am having the same issue. I have been using the same 2 SD cards and suddenly my reader stopped reading any cards. Moving the card around didn’t seem to make a difference.

I have had my CR-6 SE for almost 3 months and have used the same 2 SD cards on it daily without issue. Suddenly when setting up my next print printer would not read any SD card at all even existing gcode files already on the cards that have been used many times before. I have cycled power many time, i have even reformatted my SD card just in case. My computer can read and write to the SD cards without issue as well.

Is there a something else within the printer i should be looking at? Is this a hardware issue with the printer? Wiring issue? Software issue?

Any assistance is greatly appreciated as this shouldn’t be a failure point after less than 3 months.
