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

M586 P2 S0                                                              ; disable Telnet

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
