Indication of print in progress

[dc42]

Another way would be to configure the RPi as an HTTP client and have it make rr_status requests to the Duet. The response includes whether or not a file is being printed.

[DocTrucker]

The automatic call of an optional start.g gcode does seem like an ommision. @dc42 is there anything on the horizon?

[rubillos]

@dc42 has having start.g and end.g files ever been considered? Is there any reason not to have those?

[DocTrucker]

@rubillos end.g = stop.g

[rubillos]

And that is also called when a print is canceled?

[DocTrucker]

The http method @dc42 recommends has a few benefits.

• No extra wiring or failure points.
• If in the (unlikely) event of a process hang the http will stop responding and you can cancel your capture.

I implemented this many releases ago.

No, cancel.g is called instead.

[DocTrucker]

@dc42 documentation hasn't caught up yet.

[rubillos]

@doctrucker True. That might be the way to go... I'll have a look at modifying my time-lapse code.

There are just so many I/O pins on the Duex5, seemed like an easy thing to hook up

[rubillos]

@dc42 So start.g is called when a print starts?

Yes, whenever a print from SD card starts. I have updated the documentation at https://duet3d.dozuki.com/Wiki/Macros.

@dc42 Awesome! Thank you!

@resam has a raspberry pi camera solution as well, though I can't seem to find the thread at the moment.
