What is a good way to set up a USB webcam to return snapshot pictures (still image) via an URL? I tried this link and it seemed to install fine. But I'm not getting an image with http://127.0.0.1:8080/?action=snapshot in the raspberry browser.

That was it! Thanks Danal. Now time for a crash course in python to figure out what to do with the telnet message.

I tried using telnet to connect to the duet. I can ping it fine. But the telnet fails. the Duet & the Pi are on the same wireless network.

Inserting the gcode is easy in S3d. my problem is the python script and telnet and glue? I am a mechanical engineer. I can modify some code but I cant write it outright.

@resam I tried to use your example script but I do not know my way around python or Linux. I pasted what you have above in a .sh file, included the "#!/bin/bash" and ran the chmod to make it executable. But I get a syntax error.

Can someone post an example script file that will create a jpeg every time I send a M118 S"snap" in my layer change script. If I see how that part works I think I can work out the rest.

I have this same issue. Running Chrome Version 64.0.3282.186 (Official Build) (64-bit).
And Firmware Version: 1.19 (2017-08-14)
WiFi Server Version: 1.19
Web Interface Version: 1.19

Thank you.

One more question about the connections to the X-carriage. I read in an older post you said you can combine the common positive to reduce the wire count to the carriage.
@dc42:

You can use a common positive (V_FAN) wire for both fans.

If I have two extruders, two thermistors, x endstop, Z-probe, one heatsink fan, and one part fan, Can I combine any other common conductors? can the endstop and Z-probe share anything?

When I move my carriage around by hand and the Duet is unplugged I see some led light up and fans turning. Is the back feeding current into the board harmful? Should we avoid moving the carriage by hand?

2nd question. Can two 12V fans be wired in series on a 24V Duet? I know its not optimal but could this lead to any damage?

Thank You

That was it. I'm powering it from the 24V PS and its solid.
