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())

    c.perform()
    c.close()
    file.close()

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

Thanks!
