Serial Data cable print quality isse

Hi,

I am using Octoprint on raspberry pi zero w connected to Ender 5. I also connected DHT11 temperature sensor, and Relay to control the printer PSU.

I noticed some printing quality issues such as bobbing, but when printing the same file directly with the printer SD card, no quality issues. I tried to change the USB cable, but still the same.
Is the raspberry pi zero w not fast enough to transfer the data?
I don't have a camera connected.

Hello @Yaron!

The issue is described here: The ongoing USB Conspiracy Theory?

BTW: A RasPi Zero W isn't really not recommended for running OctoPrint. This referres to the performance in all.
