What happened?

The printer is displaying the message: This request is not compatible with the Prusa remote API. See our documentation for more details.

Error name: Remote API error

Error code: #10407 

This is shown when there is an error in the connection between the SL1/SL1S SPEED and the external system that is sending the print to be made.

How to fix it?

Some remote printing solutions, like Octoprint or Repetier host, may not send compatible commands to the SL1 or SL1S SPEED. Make sure the remote printing service officially supports an Original Prusa SL1/SL1S SPEED. If you are using PrusaLink, make sure your firmware is up to date, as features may have not been added in older versions.
