I do have a problem using the HTML API.
I have one board that always reply with 404 Not Found error when i call curl http://<ip_machine1>/rr_connect?password=<password>

curl : The remote server returned an error: (404) Not Found.
At line:1 char:1
+ curl http://<ip_machine1>/rr_connect?password=<password>

both machines have HTTP enabled.

M586 P0 S1                                                              ; enable HTTP

calling other machines with works fine curl http://<ip_machine2>/rr_connect?password=<password>

Is there any other config that might prevent that behavior. I am not aware of significant differences between both machine types.

Is there a tool that aggregate the states or the print logs of multiple printers to monitore the health, and success rate of a print farm?

What version of RRF and DWC?

• In the Video Duet Web Control 3.4.6 is used (but I think I saw it also in the latest version.)
  What browser?
• Chrome
  What operating system is the browser running on?
• Default Raspbian (octoprint image)
  What exactly did you do before the slider started moving (I don't see any interaction with the slider in the video)?
• Just dragging the slider. After releasing the slider was moving up and down. It doesn't always happen. Therefore this video was taken afterwards.

@chrishamm Thats actually a prety good idea: I can image that for some reasons there happens no explicit touchend event. (not sour where this touch end event is generated)

Sometimes when adjusting certain slider parameters these parameters keep changing without any interacting.

As visible in the video:
BouncingSlider.mp4

The Video shows a short touch interaction in the beginning and afterwards an uncontrolled change with no further touch or mouse interaction.

@droftarts Do you need quicker cycletimes than 0.33 to 5ms?
And yes this is the entire purpose of this question.

Thank you.

@gloomyandy yes exactly - The request is to use it in scanning mode.

@droftarts I am a bit confused. Why do you need to flash the z-probe? What output do you need there? Shouldn't an anlog value be sufficient for the board to measure the bed in scanning mode.

I am not expecting that duet will integrate this particular sensor. I am more expecting to have a documentation of how I can add any sensor that gives me an Analo value or in what ever way a distance to the bed.

@gloomyandy Sorry I mean that the IL300 should work for us. Here is the Link: https://www.keyence.de/products/sensor/positioning/il/models/il-300/

Was that helpful? What are the next steps?

@gloomyandy Our printer has a large layer Hight therefore we are fine with e.g. a layer height of 0.1mm.
At the moment we are using the IL 300

We are thinking about a Keyence Sensor where we can get the absolut height from the sensor.
It would be also cool to prevent with this sensor e.g. during the print that the nozzle is pushing against the printbed.

Are there any updates?

@Phaedrux so the only option is to download the files via web. Can I do this automated with wget in any way? I am also happy with downloading the entire settings folder automatically and than select locally the logs.

Is there a way to Fetch the Logfiles in an automated way from the duet2 board?
In Duet3 SBC mode it is possible to just ssh into the raspberry pi and fetch (in our case) all the files starting with "Log*".
Is there a similar way for the Duet2 e.g. a web request or something?
I am aware that I can use a Browser to open the DWC System folder and than manually select all files and than download them as a zip, but I would like to have an automated way.

What is the best way to integrate a control loop algorithms in the duet firmware. This algorithm should be able to more or
less modify life, the gcode. I am fine with having a delay of e.g. a defined buffer size before the new/modified gcode takes action.

I tried out modifying the gcode or deleting it during the print. But It looks like you are using a huge buffer or writing the gcode to a different location during print.

Streaming the gcode in the sense of sending it command by command might be a bit slow I guess?

I read here that you "may support some other [computer] models in the future" and wonder how fare this is and if someone tried out e.g. an intel Nuc instead of a Raspberry Pi?
I assume this requires some USB to SPI breakout adapter.
Does it actually require being a 40pin header?

Is there a estimated release date for the support of other analoge scanning z probes:
https://docs.duet3d.com/en/User_manual/Tuning/scanning_z_probe_calibration
The documentation just says "To come."

I would like to use a laser distance sensor.

Is it possible to set a custom timeserver on Duet2 Boards?
This is for an use case where the duet2 Board has only limited internet connection and therefore sadly doesn't continue to count the time when its off.

Are there any concerns using the Duet3D hardware for Industrial Use cases?
My main concern is the HF Interference, e.g. if you are using long Cables for CAN.

I know this question is a bit vague and also maybe more than just one question... and I am mainly interesting of the future direction.
So I know that it is possible to run Klipper on the Duet Firmware and I know that Klipper seems to be often more Bleeding edge while Duet is more polished 1.

From my instinct and understanding: Klipper is doing all the calculation on the Computer (e.g. the Raspberry Pi).
A) Is this also true for the Duet?
What I tried out is: using a Raspberry Pi 4 and a Raspberry Pi 5 with Duet and run a speed test gcode up to a limit/problem: and starting with a speed of S25000 I run on both units into Hiccups.
(Note: There is a claim that it doesn't matter to much for steppers - but well I want to use servos... 2).
B) Are the Hiccups an issue?
C) Are they maybe caused the DuetBoard or the bus system and not the Compute unit?
D) are there any performance improvements from switch to Klipper (and a powerful computer)?
