Solarflame5 commented 1 month ago

Steps to reproduce

  1. Open an OctoPrint instance in your browser
  2. Start a print and start waiting
  3. Eventually(takes around 20-30 minutes) the tab will become really unresponsive, and the Firefox task manager will show high RAM and CPU usage for the OctoPrint tab.

Description

The issue disappears when I disable the Link Hints extension and try using OctoPrint again in a fresh tab.

image The tab freezes for a couple of seconds after presing Alt + J, and Firefox shows a warning.

Hi!

What does “open an Octoprint instance” mean? How do I start a print?

Solarflame5 commented 2 weeks ago

I'm sorry for the vague and hard to replicate bug report.

OctoPrint is a 3D printer management software with a web interface, "open an OctoPrint instance" means to start a server running OctoPrint and connecting to its web interface in your browser. To start a print, you need to slice a 3D model in a slicer software and upload it to OctoPrint, and then start a 3D print of the sliced file.

Thanks! That sounds cool! But also too complicated. I’m not into 3D printing (yet?). So unfortunately you’ll need to debug this yourself, or hope that somebody else shows up who also has this problem and has the possibility to debug.

No problem! Just wanted to keep the bug documented somewhere.
