Can OctoPrint turn off my printer?

Hey tech lovers! It’s Carolina here, your techno-guru who’s obsessed with sharing every byte of information I love. Hold on to your keyboards because we’re diving deep into OctoPrint issues that have been bugging many of you.


Troubles with OctoPrint Keeping Your Ender 3 Screen Lit? Here’s the Fix!
1. Properly Boot and Close Down the Pi
2. Shield the 5V Pin Using Tape
3. Sever the 5V Cable
4. 3D Fabricate a Protector for the 5V Pin

Did you know? A sneaky troublemaker called back powering is often the culprit when OctoPrint refuses to let your Ender 3 screen rest. This mischievous act happens due to the USB connection from the Raspberry Pi to your 3D printer sending power, even when you think it’s off! A tiny 5V terminal remains active and can make your printer seem awake. Not cool, right? And guess what? This can mess with your printer’s circuits!

How to Put that Ender 3 Screen to Sleep:
– Start and Shut: Always begin and end sessions by turning on and off both the printer and the Pi in the right sequence.
– Block the 5V Terminal: An old-school trick! Use tape to block the USB’s power transfer. Detailed instructions are available on the OctoPrint forums.
– Slice that 5V Wire: A tad messy but super effective! Expose the wire, cut the red one, tape it up, and voila!
– 3D Design Solution: Print a USB-A Male Plug Pin Insulator using a design from Thingiverse and slide it over your USB.

Fed Up with OctoPrint Crashes or Disconnects? Let’s Mend It!
1. Switch to a Different USB Cord
2. Examine the USB Port of your Printer
3. Shift Electronic Gadgets to Another Circuit
4. Monitor for Electromagnetic Disturbances
5. Refresh Your Wi-Fi Device
6. Apply Tape on the 5V Line

Handy Hints:
– USB Cables Matter: Sometimes a sturdy, short, and shielded cable, like Amazon Basics or Anker Cable, can do the trick.
– Tighten Those Ports: A user realized a loose USB port was the villain! By angling and securing the cord, peace was restored.
– Be Circuit Wise: Sharing circuits with other devices? Maybe not the best idea. Another gadget might just be your OctoPrint’s nemesis.
– Beware of Invisible Troublemakers: Objects such as heaters, microwaves, and vacuums might cause interference. Keep your eyes on those OctoPrint logs!
– Router Reset: A tech-savvy user switched routers and solved his connection hitches, sometimes it’s the tools we overlook.
