When printing, the extruder motor has a clicking sound and it is very repetitive - about every 2 - 3 seconds and it looks like the drive sprocket bounces back slightly with each click. Print is not coming out very well. Any thoughts? Thanks

Have the same problem with my new Ender 3 Pro. Got on it 9-20-2020 and ran until 9-27-2020. Same situation as you and Guzz. If you remove the card it boots up and has the normal menu. No response from customer support yet.

My new Ender 3 Pro bricked after within 10 days and the SD card which came with it is unreadable. When I tried booting the unit up with the card in it, it only has a backlit screen and no display. When I remove the card - the unit at least boots up fine and shows a menu. I put in a 128G card I had but it is exFAT formatted - same problem.

Will the Pro version not accept anything but FAT formatted SD card?

I had a similar problem. New unit worked for about a week. I found removing the SD card and reboot brought the unit back to life. But, when I put the SD card back in, it sensed the card but the main display indicated No TF Card. If I reboot unit with card in place, the unit would not start - only backlit display. SD card is not bad. I tried a new one I had, it has the same problem with No TF Card. Have waited 2 days for tech support - nothing yet.
