Duet embedded server stops responding after upload

  • Hi!

    I am having problems trying to automatize my Duet uploads.

    I use pycurl to upload to rr_upload. And it is being successful most of the times, but every now and then the same file makes our duets to stop responding with a URL ERROR [[Errno 111] Connection refused.

    The printers keeps printing, but we cannot longer communicate with it. I tried different firmware versions.
    I can ping the printer and it responds back.

    Anyone experienced this kind of problem before?
    Here is my current code to upload to the duet

        c = pycurl.Curl()
        upload_url = "http://%s/rr_upload?name=gcodes/%s&time=%s" % (self.config['ip'], onlyfiles[0], get_timestamp())
        file_name = join(self.print_folder, onlyfiles[0])
        c.setopt(c.HTTPHEADER, ["Content-type: application/json"])
        c.setopt(c.URL, upload_url)
        c.setopt(c.POST, 1)
        c.setopt(c.VERBOSE, False)
        file = open(file_name, "r")
        c.setopt(c.POSTFIELDS, file.read())

    Is there any example of using python to upload into the Duets?

    Hi, try sending a rr_disconnect http request after the file upload completes. That will free up the server resource. HTH David
