Printer disconnect mid print

[mojo265]

What is the problem?

Printing via octoprint on raspberry pi 4 keeps disconnecting mid print

What did you already try to solve it?

Prints are perfect from SD card.
Tried multiple cables.
Installed fan on Pi.

Have you tried running in safe mode?

nope

Did running in safe mode solve the problem?

To test

Systeminfo Bundle

You can download this in OctoPrint's System Information dialog... no bundle, no support, unless the reason you couldn't retrieve the bundle is your network issues

Here are some replies I have given in the past to that issue

Printer Disconnects Mid-Print

That's unfortunately a common thing with some Ender 3s. Those printers are prone to EMI. Since you already got a quality usb cable I can only suggest to check for other devices that could emit EMI. That could be for example a microwave, a washing machine or vacuum cleaner. I had also good results with tin foil - wrap the mainboard box in it (but don't cover the fan venting holes)

Printer Stopping Randomly and disconnects from Octoprint

No worries Creality printers are known for having this kind of issue. It's most of the time caused by EMI. EMI can be emitted by a lot of things like fluorescent tubes, ACs, fridges and sometimes even when you sit down on an office chair with a gas cylinder in it. Things you can try: print with and without an sd card inserted into your printer (you don't need to print from the card - we just had some cases where it helped with some weird issues). if you have something nearby that could…

Bad prints with FLYING BEAR Ghost5

I see a lot of transmission errors in your log. You should try another USB cable - preferably a quality one with ferrite beads. Try to keep the cable as short as possible and don't run it next to the stepper motors. Also is there something nearby that could emit EMI (like a fridge, an ac, etc)?

Anycubic predator connection problem

Did the other cable work a bit better? An error at line 23 is pretty early so I guess there is a bigger problem. If it was as bad as the other cable there could be something nearby that emits emi like a microwave, a refrigerator or a fluorescent light.

looks like problem solved i ran cable underneath the printer as pi was at the back. Thank you for the help
