@Phaedrux I thought that it helped to reinstall everything. First everthing worked well, but after configuring my RPI in the way I typically use it, i got the same problem again.

But I was able to find the point where something is going wrong.

What I have done:

Completly new image on SD card (v3.2). Everything worked correctly: DWS webpage is shown correctly in my network.

I want to run another Singlepage-Application an the RPI therefor I install nodejs with the following command

sudo apt-get install -y nodejs npm

and after finishing the installation, something is wrong with the Appache-Server (?).

Results:
And I get my old error message: "Apache2 default message"

Question:
Is there an Apache expert who has an idea?
How is it possible that the installation of nodejs is changing something that leads to my problem with the Apache?

RPI are supporting docker containers and there is a general trend towards containerization.

Wouldn't it be nice if DCS DWC and DWS are running in on a docker container?

Did somebody tried something similar?
What is your opinion about that? Do you see more advantages or disadvantages?

Could somebady explain me why there is high difference in total speed if my gcode looks like

a)

G1 X1
G1 X1
G1 X1
...
G1 X1

100 times.
or (b) just:

G1 X100

Less gcode is faster? Why is the firmware not optimizing that?

@Phaedrux It's just that often I am not finding what I am searchingt for.
Probably I am using the wrong search terms, but to give you example search for term like,

"5v power supply problem"
"Changing ports of DWS"
"Wiring neopixel"

and 95% of the posts which will be shown are not really correlated to what I am searching for.

My personal experience is that the search function in this forum is very limited. Most of the time I find the right forum post rather when I go back to Google and search there.

Does anyone have any idea what the technological problem is? Would something like "tagging" be useful?

And the STEP fieles ofat least 1.0
here https://github.com/Duet3D/Duet3-Mainboard-6HC/tree/master/Duet3_Mainboard_v1.0

@TLAS Thanks fo the hint.

I found the schematics in https://github.com/Duet3D/Duet3-Mainboard-6HC/blob/master/

Does a free CAM/CAD model of the Duet3 MB6HC exist anywhere?

and second question:

Does somebody has created a fusion 360 electronic library block for the Duet? I would like to use it for my circuit plan.

As so often: @chrishamm has the right answer!

M586 C"*"

helped! Thanks!

@chrishamm Ok? That's interesting. I used http://192.168.1.7:1000/ and checked that it was http and it did not work.

Changed my config back by removing the port. Restarted Server -> worked again.

@chrishamm recommended me for another problem to change my DWC port.

I changed
/opt/dsf/conf/http.json
into

...
  "Kestrel": {
    "Endpoints": {
      "Http": {
        "Url": "http://*:1000"
      }
    }

...

but after an restart, even if I was able to connect to //my:1000 and DWC was responding, the DWC is not able to connect to the Duetboard.

Is there a second config file which I have to change?

Setup:
SW 3.2 Duet3
not standalone mode

@chrishamm Thanks I will try that!
