HELP: Can't connect to P1S today with Bambu Studio

Bambu Lab Software
1

This is really weird. I have been using my P1S almost continously for 3 months. It has been connecting fine to Bambu Studio, but as of an hour ago, Studio does not find any printers.

  • I am logged in in Bambu Studio, printer is completely gone. Not using LAN only mode.
  • Restarted the printer
  • Bambu Handy finds the printer immediately, no problem
  • OrcaSlicer took about a minute but found the printer (I shutdown Bambu Studio first, I do not try to use them both at the same time)
  • Shut down Orca Slicer, tried Bambu Studio again but still no luck.
  • Ping from my Mac Studio to the printer works fine, about 12ms latency

Not using any beta firmware or software.

What the heck?

Completely removed Bambu Studio and the ~/Library/Application Support/BambuStudio folder. Reinstalled and it’s working again.

bet you coulda just waited it out, mine did same thing but ended up working on its own. support said they were aware.

Well, I have to confess one thing. I had tried copying the new SUNLU profiles from Github. I only copied the SUNLU folder and modified BBL.json to add the new ones - not sure how that could have messed me up, I was pretty careful. No syntax errors, nothing to do with the printer connection. Bambu Studio was also crashing on exit.

What happens when you uninstall and reinstall Bambu Studio?

After I uninstalled completely, and removed the application data, I was able to get in again.
