Octoprint causing random layer shifts

[Meierme176]

What is the problem?
When uploading gcode locally to my octoprint that is connected to my Geeetech A20M at random times the print will shift. Even if I rerun the same print, it has a chance to shift. It doesn't shift at the same layer and it has only shifted once per random print.
What did you already try to solve it?
I have tested just using the SD card and bypassing Octoprint. Doing so provides flawless prints so I have indeed localized the issue to being with Octoprint and not my hardware.
Logs (octoprint.log, serial.log or output on terminal tab, browser error console ...)

Hello @Meierme176!

Have you tried the safemode?
Also the serial.log would be quite handy.

Do you use marlin 2.0? I'm asking because layer shifts are a known bug in marlin 2.0 and sometimes even on 1.1.9. Most of the time idex printers are affected.

the serial.log would be quite handy

Sorry, I would have provided that but im not actually sure how

[Meierme176]

Do you use marlin 2.0? I'm asking because layer shifts are a known bug in marlin 2.0 and sometimes even on 1.1.9. Most of the time idex printers are affected.

I will check as soon as I get home. If I am, should I try to install an older version or do I have to wait until a fix comes along?

Well first I would check safemode as @Ewald_Ikemann suggested.
Then we should check your logs. You can find help to serial.log and logs in general by clicking on the blue words.
If you didn't modify your printer you should be on 1.1.9 or 1.1.X (which is very close to .9)
here you find your latest official geeetech firmware https://github.com/Geeetech3D/Prusa_I3_3Dprinter/tree/master/A20M_Marlin-1.1.x12864

I also experienced layer shifting. It happened after I started having wifi issues.

On my PC, I started experiencing another possibly unrelated issue. I could connect to Google, and run searches, but no other websites had connectivity. I restarted my computer and saw that Windows 10 was demanding another update (I've had the web problem in the past and Windows 10 requiring an update is a common theme). I'll try running the print again in safe mode and I'll let you know if I experience it again.

I tried adding the serial log, but I couldn't find %APPDATA%\OctoPrint\logs on my PC. I'm guessing because I need to look for it on the Pi itself, and not my PC??? Let me know if / how I can add more data. I would have pulled the terminal log, but I didn't think of it at the time.
