@RandomFactoid maybe I can implement something that will help you:
In the DuetRRF plugin, before actually uploading the new file, I could check if a file with the same name already exists. If yes, you could select "Overwrite" or "Restart print with this file". This assumes you have Cura still running with you current model & build plate.

Would this be of help to you?

I just upgraded to 1.21 and the issue appears to be resolved now. ☺

And I think duet doesn't have enough CPU power to do any kind of video streaming and printing at the same time.

I'll add the bed compensation status to the M408 status report in the next firmware release, which will make it possible for DWC to display it.

Added to the list.

Just an update.

I added a feedrate to the G1 command and now they show up in the DWC properly.

G1 Z[first_layer_height] F600

Here is another interface to the DUET web service api. This one is designed to monitor multiple printers, and provide a few simple controls.

No problem for me Ill just input the URL on all the devices I usually use. Thanks for the helpful response.

Perfect thanks!

Just looking for this feature as well.
A lovely graph or other graphic display will always be nice, however…
initially I would be happy to have Machine Status -> Extruder Drives show mm/sec over last 3 (? maybe configurable 1-5 in settings) seconds.
Obviously this will dissatisfy those who get value out of seeing the mm extruded here, so maybe having a toggle on the display would be nice .. and then people will want toggles to show mm/sec for each of X, Y, Z and E[n].
So this would be same update rate as currently shown, just some adds and a divide to calculate the display value.

Well, no luck with the repeater yet. I didn't do a whole lot of debug - just went through the quick start routine. It actually made things worse. The Duet couldn't connect at all if the WR810N was nearby. I can try setting it up as a router instead since I have ports available but at this point I think I will try the board swap.

im using the pi for the webcam and got it to work finally. right way up now

sudo killall mjpg_streamer ./mjpg_streamer -o "output_http.so -w ./www" -i "input_raspicam.so -fps 30 -rot 180"

the -rot parameter is adjustable of course

Ahh yes, somehow I answered an earlier question.

To answer the new question - Its simulate in the same menu as edit.

See the end of https://github.com/chrishamm/DuetWebControl for instructions on how to do it yourself.
