Random printer stops during print

What is the problem?

When printing the print stops, sometimes this is for just a second or so and sometimes for minutes
I have tried a simple print "XYZ Cube" and it has even stopped while printing the skirt

What did you already try to solve it?

Changed the power supply for a genuine Pi Charger
Changed the USB Cable to the printer
Print from SD Card or Local saved files
Prints OK directly from printer not using octoprint
Print in Safe mode
I have only had Octoprint for 2 weeks and had no successful prints yet as its new it could be I'm missing something but don't think so

Have you tried running in safe mode and if so did it solve the issue?

Safe mode made no difference

Have you tried without the SD card in the printer?
There are already 100 files in the trash folder there.

No but I will now

Tried without SD card in printer and stopped printing on layer 3

Thanks for the suggestion it was worth a try

So at every layer change there is this:

There is M400 to wait for to finish the last move.
Do you have Octolapse running?

I did yes but after turning it off and running in safe mode the same stopped printing still happens

Can you share the logs from safe mode?

Looks like logs turned off when I put in safe mode, I will turn back on and rune another print

Looks like I get this message in terminal when print stops

Latest Logs can't get logs in safe mode don't know why

Try isolate the 5v power connection (inside USB cable) from raspberry to printer.
There could be an issue when both have there own power supply.

You can try to significantly increase the timeouts. I had to do that for my printer a long time ago to avoid print crashes.

Thanks to all those who suggested a fix, the problem turned to be a faulty printer board..

Thanks to bigtreetech for refunding the cost of the board and help in finding th3 cause of another problem that was also the board
