On Multi-Object Prints in Klipper , you might see the message:

1

Unknown Command "M486"

To me that happened when i switched to Superslicer .

Thankfully it is easy to solve:

  • Open Superslicer
  • Open your Print Settings
  • Search for “Label Objects” (should be in “Output Options”)
  • Uncheck the tickbox

That solves it ;)
