  @snufkin said in Firmware wishlist and priorities for Duet WiFi and Duet Ethernet: My vote is: True bed levelling using 2, 3 or possibly 4 independently-driven Z motors and a Z probe. This one exists now. https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors Automatic advance of changes in the colour mix when using a mixing hot end. See deckingman's blog. Support for PanelOne 20x4 text displays, or possibly 12864 mono graphics displays. The Duet Maestro supports 12864 displays. The other Duets lack the hardware needed. But there are other alternatives to the PanelDue now as well. Cheap tablets as a web interface or even a customized simplified interface. https://forum.duet3d.com/topic/9257/dueui-1-1-0-is-released Ability to update PanelDue firmware via the web interface. Still on the wishlist. Ability to control an electronics cooling fan thermostatically based on CPU temperature and driver overheat warning. This is now possible as well. https://duet3d.dozuki.com/Wiki/Mounting_and_cooling_the_board#Section_Cooling Thanks for all you do for the community!

  @Danal said in RRF3 / Duet3 with Pi: execute bash through M code: @dc42 said in RRF3 / Duet3 with Pi: execute bash through M code: It would be perfectly possible (and probably straightforward) to take a Telnet client and have it talk to the API provided by DSF. But Telnet is horribly insecure, so it would be much better to implement SSH or another secure alternative. Completely agreed. But there it is on D2. Hmm.... And it's disabled by default. And we tell users not to make a Duet accessible to the Internet without using a VPN.

  @dc42 I understand that. The macro early in this thread that takes 10 measurements at the point X151 Y161 works fine in the /sys folder. However, if it is edited to remove the X and Y co-ordinates like: M291 P"Probe will be tested 10 times and return mean and standard deviation. Ok or Cancel?" R"WARNING" S3 ; User must click OK or cancel. G28 G30 P0 Z-9999 G30 P1 Z-9999 G30 P2 Z-9999 G30 P3 Z-9999 G30 P4 Z-9999 G30 P5 Z-9999 G30 P6 Z-9999 G30 P7 Z-9999 G30 P8 Z-9999 G30 P9 Z-9999 S-1 it does not stay at the current position but moves in X. I believe it should just take 10 points at the current location without moving.

  @littlehobbyshop well, for a gcode that short it would work using macros, yeah. but if I want to print say 100 or 1000 files that might get a bit messy without the print control interface? also pause would not work either? My idea for m28 is to change a macro file to start the next print, but I ran into other issues there.

  @mmiscool said in Ability to use real serial as default interface rather than USB.: that knocks out the USB interface from time to time. I hunted USB problems between a Pi and a different controller board (Planet CNC) for weeks. Manifested as a USB disconnect that would occur every 5 to 20 hours when cutting. Everybody thought it was EMI. Near the end of the debugging, had just the Pi and the PCNC board in a cage. Still happened. Tried all kinds of things. Including 3 different Pi 3B+ boards. Really, lots of hardware changes. Excellent support from the PCNC people; many suggestions. Turned out the Pi 3B+ has known USB issues. Very hard to pin this fact down with Google searches... (hard to separate Pi versions, and a huge signal/noise ratio with many posts that blur the 3B+ issue). If you read very carefully it becomes apparent. In my case, switched to a Pi4 and USB became completely stable. Tested for 30 and 40 hours at a time in the cage. Put the setup back in a CNC router that uses 70V Nema 23s. Perfect. Several 20 and 30 hour cuts. Many, many, shorter cuts since then. I have read that perhaps Pi2 and Pi3B (not plus) are also USB stable but have no direct experience either way. Summary: Pi3B+ will disconnect USB every few hours; Pi4 is USB stable.

  I am on board for the ability to cancel object on the Duet 2 for sure. I use the cancel object or exclude region in octoprint when a small piece breaks free on a plate full of items. This has saved many prints from being complete failures.

  One of our plans for Duet 3 is to have a "Read ahead" GCode stream that reads the printing GCode ahead of the main stream and simulates them, looking out for operations coming up that have an associated delay - such as changing the filament mix in a mixing extruder, and switching to a different tool that needs to be heated up. Then the firmware will be able to advance those operations.

  I would prefer a real time thing, probably something that could slow down the step clock if the filament extrusion is getting a bit behind.

  Gotcha. I thought it might be too complex to implement, but doesn't hurt to ask. Thanks for the explanation

  @kraegar said in M220 apply to only printing moves: I'm talking about for a print already on the printer and printing... you know, like when you'd say "oh, I'm printing too fast, let's slow it down a tad..." Ah... Understood. Frederick

  @nikscha said in Allow to use different idle currents on different drives: @deckingman that sounds promising. The extruder is controlled by macros for the most part. In that case it's easy. You could simply use M84 to turn the idle hold off completely when not in use. You can't do that with an X,Y or Z motor because it will reset the homing status, but I can't think of any reason why you couldn't do it with an extruder.

  Thanks for clarifying, I was going off the assumption that I had already defined sensors and heaters.
