M291 should be able to show images from SD card
-
Hi everybody, i am a newbie on this forum , but already spent more then 7 years of my life with Duet boards.
So now I am trying to make a "dumb-user" friendly printer, based on Duet Wifi + PanelDue. I have created a handy menu using macro folder, i am able to conduct a dialog with user, but sometimes I need to show a picture to explain in more convenient way what to do next. It would be very handy if M291 command with some flag be able to show pictures from SD card.I hope this feature is can be implemented and our Godlike developers have this in their plans?
P.S. Also would be great to have same feature in DWC

@Swaper The Duet devs might not be godlike, but they are indeed really close if I take a look at the amount of great support they do here. It might help to leave out the sarcasm though when posting a request...
I had the same issue when I created my printer calibration routine. My guess is the biggest obstacle would be missing computing power of the display - just take a look how long it takes to show the preview picture if you open the details page of a gcode file on the PanelDue.
I would get crazy if a message popup would take that long to show me the picture
If you happen to be able to display your instructions using ASCII art, that might work - as long as you can do it in one line at least, since M291 also does not support line breaks. This is how I solved that obstacle in my case...
But I fathom it would probably be easier to implement a line break for an M291 message than to get a picture onto the PanelDue with a remotely decent speed.

@Swaper pictures on a paneldue are unlikely to be possible at a sensible speed.
