405: Method not allowed when trying to send a print job over the API

Posted · 405: Method not allowed when trying to send a print job over the API



I have a weird issue I'm kind of stumped on. I have a Docker container slicing customisable print jobs with CuraEngine which it then sends to the printer via the printer API.

This setup has worked so far, but today I restarted the Docker container and now get a 405: Client Error METHOD NOT ALLOWED error when trying to send the printjob to the printer with

requests.post(http://192.168.1.x/api/v1/print_job', files={'jobname': jobname, 'file': gcode_file}, auth=requests.auth.HTTPDigestAuth(ILAUMS5_USER, ILAUMS5_PASS))

Usually a 405 error indicates that the method used is not allowed for the endpoint I'm trying to reach, but the /print_job endpoint can be reached both over GET and POST, so this should not be the issue.

I have also verified that the credentials are valid, the file exists and the jobname is valid.

Does anyone have an idea what I am missing? Any help is very much appreciated.

    Hi @xsimplex,


    From the information you provided I don't see any particular reason why this should not work. If your authentication is okay there are a few other reasons you could get a not allowed:

    • Your request is not properly formatted.
    • The printer is not ready to accept printjobs. For example, this can happen when you are currently printing. Or if the printer is in any other status than 'idle'. After the a printjob the printer will only go back to idle after you've pressed confirm removal.

    You can check the status of the printer using the api /printer/status. I hope this helps for you. If not please let me know.
