Duet and external integration

[strips]

Hi,

I think I have read something about this somewhere but can not find it.

I'm primarily looking for a way to send a signal to an RPI and triggering time lapse videos of a print. This could be triggered by some API, TCP, GPIO, serial and so on.

The signals could be sent by a GCODE command or special configuration in firmware.

Usages

• Start stop recording video

• Trigger for time lapse

• Send state/info to home automation devices. This could be started print, stopped print, heaters on/off, failures and warnings, preferably by REST API

• Recieve alarms from home automation. E.g. if fire alarm is triggered a print could be shut down.

Maybe a gcode on layer change that trigger a photo from the rpi? You can take 1 for layer and then make the video.
The PS_on pins can simulate the switch with a relay

Thanks David,

GPIO 1-4 on Duex5 should be possible to use for integration to RPI.

Still think REST API could be useful as well

The REST API is being considered.
