Fix OctoPrint always on printer display

If you are an OctoPrint user, you probably noticed that the printer display is always on. This is caused by the USB connection powering the printer display and motherboard.
Today I will show you an easy fix for the OctoPrint always on printer display.

Why is this happening ?

In order to fix the Octoprint always on printer display, we first need to understand why that happens. A typical USB connector has two data lines, and two power lines.

By blocking the 5V power line on the connector, we cut the power going to the printer therefore fixing the always on power issue.

That’s it!

Now that the +5V line has been insulated, your printer display will stay off when the printer is not used. This eliminates the need for unplugging the USB cable, and fixes a little annoyance.

Happy printing !
