Hi, Still having trouble with my “3s1pro” turn on this morning, level the 5 points all good, auto levelled seemed fine, hit PLA preheat as a normally do and inserted sd card as I waited for all to heat. selected file, returned to main screen, heat achieved, pressed print and waited. printer turned off and restarted. :0/ help.
I’ve seen in a few other posts lately that if a file name is not written correctly or has a special character or is too long that the printer will not process it…
Maybe try another file or card…??

Here some reasons from the top of my head:
- Power Supply Issue: Make sure the printer is plugged into a reliable power source. Problems here can cause the printer to restart.
- Firmware Problem: Update or reinstall the printer’s software from Creality’s website to fix any bugs that might be causing issues.
- SD Card Issue: Try a different SD card or reformat it, as problems with the card or files can cause errors.
- Loose Connections: Check that all cables inside the printer are properly connected and nothing is loose. Make sure the printer is heating up as it should. Issues here might need a closer look at the hardware. Like the cable of the thermistor and the hot rod.
- Factory Reset: Resetting the printer to its original settings might help.
Your issue is kinda random, but these are the things I would do if I have your problem.

Thanks’, ill try renaming it tomorrow
okay, it seems my problem is with the card reader. dose this mean I need a new motherboard?.
If you are certain there is a problem with your card reader you might need to contact Creality support for a replacement. I think this is the link:
Hope they get you a solution soon.
