PS it's this one https://forum.duet3d.com/topic/9626/new-m-code-to-send-a-network-request/11

status is the easy part. connect to duet with
http://a.b.c.d/rr_connect?password="xxx"&time="2018-04-09T21:46:00"
and then poll
http://a.b.c.d/rr_status?type=3

I do that on my node-red server that provides a GUI with the status of a printer

ok thanks,

i followed this tut (http://richmondsystems.net/2017/06/18/using-arduino-library-in-eclipse/ )
step by step but at the and i'am getting a bunch of errors:

0_1537249502820_Bildschirmfoto 2018-09-18 um 07.44.42.png

as you can see, i used here the ESP8266RestClient- library, because i can't found the ESP8266HTTPClient - lib under Eclipse -> Preferences -> Arduino -> Libraries.

Thank you, but i meant how i can log from the Socketserver.cpp?

you are using version 0.4.12.
i updated to this version and im getting now a perfect .bin-File

@eberlin said in control multiple printer with node.js server:

I want to control my printer over the Internet.
I know that the duet3D firmware has method headers prepared to open TCP connections.
My problems is, I don't now how to implement them in cpp and how to receive any sended status message with my node. Js server

Two parts to this.

First, establishing a connection between the printer, which is an IP address on your private network, and your node.js on the public internet. There are MANY ways to do this SECURELY. Personally, I would run a reverse proxy... The details of setting this up are HEAVILY dependent your your LAN and Router setup, ISP, etc, etc. Therefore, you won't get that much help here on the Duet forum. There are many tutorials, or seek the help of someone who knows.

.

Second, how to have node.js talk to the printer. That is what is documented at chrishamm's github. It is all simple HTTP GET requests. That is the only thing the printer fully supports for control and status.

You can see this in action by entering a few of the commands in a browser. Something like:

http://192.168.86.100/rr_status?type=2

Will result in:

{"status":"I","coords":{"axesHomed":[1,1,1],"xyz":[0.000,0.000,622.124],"machine":[0.000,0.000,622.124],"extr":[4935.9]},"speeds":{"requested":0.0,"top":0.0},"currentTool":0,"params":{"atxPower":0,"fanPercent":[0,100,0,0,0,0,0,0,0],"fanNames":["","","","","","","","",""],"speedFactor":100.0,"extrFactors":[100.0],"babystep":0.000},"seq":93,"sensors":{"probeValue":0,"fanRPM":0},"temps":{"bed":{"current":21.0,"active":0.0,"state":2,"heater":0},"current":[21.0,19.9,2000.0,2000.0,2000.0,2000.0,2000.0,2000.0],"state":[2,2,0,0,0,0,0,0],"names":["","","","","","","",""],"tools":{"active":[[0.0]],"standby":[[0.0]]},"extra":[{"name":"MCU","temp":34.5}]},"time":1027270.0,"coldExtrudeTemp":160.0,"coldRetractTemp":90.0,"compensation":"Mesh","controllableFans":5,"tempLimit":290.0,"endstops":4088,"firmwareName":"RepRapFirmware for Duet 2 WiFi/Ethernet","geometry":"delta","axes":3,"axisNames":"XYZ","volumes":2,"mountedVolumes":1,"name":"Danal's BFD","probe":{"threshold":100,"height":-0.10,"type":5},"tools":[{"number":0,"heaters":[1],"drives":[0],"axisMap":[[0],[1]],"fans":1,"filament":"","offsets":[0.00,0.00,0.00]}],"mcutemp":{"min":32.5,"cur":34.5,"max":38.3},"vin":{"min":24.8,"cur":25.0,"max":25.3}}

The printer never "originates" anything. It MUST be "polled".

@dc42 said in Cant build DuetWifiServer:

I did an interim 1.22 release to fix a bug. I checked the Expressive SDK at the same time, but unfortunately they haven't yet released a version of the 3.0 SDK that looks easy to integrate int DuetWiFiServer. So I may add the outbound connection support to the existing version.

this would be great
