[Ultimaker S5 print via API]

Hello,

I am trying to start a print via the RUST-API, but unable to do so because I don't understand what the problem is,

I have written some code, which is attached, and when I try to run the start_print.py, I don't understand how it sends the gcode via this CURL request:

curl -X POST --header 'Content-Type: multipart/form-data' --header 'Accept: application/json' -F jobname=test 'http://192.168.4.12/api/v1/print_job'

 

Thanks in advance,

Jurgen Kuyper

[problem trying to start print via Ultimaker 3 API]

Hello, I recently started playing around with the Ultimaker 3 API, and everything is well, except that I cannot figure out how to succesfully send a file to be printed via the api, everything I've tried either results in a response 400, or 200, not the required 201 to start the print.

the full code is attached as reference. thanks in advance!

Hey, I am trying to start a print from your code, the UM3_API.zip, but after adding the ip to the start_print subroutine it still won't work on my UM3, I get the response 400 bad request back, do you happen to know what's wrong?

dunno... but i would not use the "api" object at all for this task.

The cluster-api works different, no authentification, and does not know the "jobname" parameter (AFAIK).

 

Can't you simply mimic the curl command with a python library or such....?

I tried that already, but then I still get the 200 back instead of 201

I'm not sure, either this (older) network printing doesn't work anymore or we use it in a wrong way?

I use only the new API for this, i hope it still works in the same way in this new "digital factory" age (my UM3 has not heard yet of those fancy things... 😏)

 

Have a look at the documentation on the printer.

http://169.254.168.50/cluster-api/v1/

 

Something like this (from a windows batch file):

 

set URL=http://169.254.168.50:80/cluster-api/v1/print_jobs/
set FILENAME=UM3_UltimakerRobot_support.gcode
curl -X POST --header "Content-Type: multipart/form-data" --header "Accept: application/json" -F "file=@%FILENAME%" %URL%

okey that works, but when I try to do the exact same thing in my python code I get a response 200 back, and the print doesn't start.

import UM3_API
UM3_API.start_print("UM3_UltimakerRobot_support.gcode")

.......

def start_print(file):
    api = initAPI("169.254.113.5")  
    if os.path.exists(file):
        jobname = os.path.basename(file)
        filepath = file
        print(filepath)
        print(api.post("cluster-api/v1/print_jobs", headers={"Content-Type": "multipart/form-data", "Accept": "application/json"}, files={"file": (jobname, open(filepath, "rb"))}))

what am I doing wrong?

I learned here that Postman and the firmware do not speak the same dialect of "http digest" somehow...

But the python script works like a charm

I tried that, but I get a missing argument error on the api.loadauth subroutine, cus the "auth.data" is going in to self, and the filename is not specified, if I add that it doesn't work either, I am using python 3.7.5

[Ultimaker S5 API authentication problem]

Hello,

I have a question about the rest API,

When I try to authenticate using a key and id I got from /auth/request,

It always returns the 401 authentication required, no matter where I enter it on postman.

does anyone know what I am doing wrong?

thanks in advance!
