Printer not printing after updating and also installing remove/dev/ttyS* Ports

What is the problem? Printer not starting any print or moving when pressing control in the octoprint dashboard. Also not changing temperature.

What did you already try to solve it? Restarting, rebooting, installing Remove /dev/ttyS* Ports (port auto detection fix)
Uninstalling the webcam from the Pi

Sometimes this shows up, sometimes it does not.

I have an Ender 3 Pro. Usually connecting with Ultimaker Cura and also checking progress on spaghetti detective.

I did not print for a while but wanted to be able to print in help of the Covid -19 pandemic.

If you need any additional information please tell me. Thanks for your help.

Best regards,

Hello @yannickh2!

You may check your power supply:

Hi Ewald,

thanks. I put tape on the 5 V pin and the printer did not turn on at all anymore. No more lighting up of the Display. Maybe something is misconfigured? Output of power supply is 5V and 3A

So I assume the printer is not powered with it's own power supply?
Take care to put the printer to it's own power supply/power outlet for it is not powered by the Raspberry Pi.
