What is the problem?
Octoprint connects and start printing but
Prints fail at random points
What did you already try to solve it?
Reflashed octoprint
Covered 5V pin with tape (my printer won't connect if it's covered)
Bought correct raspberry pi power supply
Tried another cable (made sure its away from other cables)
Different SD card
Firmware is updated
Have you tried running in safe mode and if so did it solve the issue?
I have tried it without any plugins installed

I also get the

Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
octoprint 1.4.2 (I have tried different versions)
RPI 3B+
Longer LK4 printer
I have read from amazon reviews that people got their LK4 to work with octoprint just fine. I'm not sure what the problem is with mine. It could be they just have broken firmware but what is the fix for that if I already have the updated firmware.
Thanks!
