Duet WiFi firmware new feature priorities
-
H. Grid-based bed compensation
B. Multi-threaded web server
E. Support for an external SD card socket
L. Faster file upload speed
J. Dynamically-varying microsteppingSomething not on your list that was previously discussed on the delta forum was adding better support for webcams. I'd add to that the ability to record timelapse photos/video.
Thanks!

Are people who are voting for faster upload speeds aware of the progress that has already been made in the latest firmware? I can't say how fast mine is uploading (over wired LAN) because I haven't uploaded anything larger than 1.8Mb which happens so fast that I don't have time to register the speed. Maybe if I looked hard at the screen when I pressed the upload button, I might see it, but it has to be in the order of a couple of seconds or less.
-
As far as I am concerned I am seeing a reduction of 40-50% in file upload speed as compared with the (wired) duet 0.8.5.
Typically I would see upload speeds of circa 950 Kb/s compared with 500-540 Kb/s on DuetWiFi. Respectable but noticeably slower. Admittedly in my area there are often ten to a dozen wifi channels competing with my setup.
This is the main downside I see with DuetWiFi compared with 0.8.5 - pretty much everything else is a plus. I particularly like the reduction in noise from the steppers and I love the thermocouple interface board. Looking forward to the extra features David is planning to add to the firmware.

J. Dynamically-varying microstepping
I. Faster microstepping
C. Predictive temperature control
M. Babystepping
S. Support for DS18B20 temperature sensors -
- Support for PanelOne
- Support for restore points
- Support for a config-override.g file
-
- . J Dynamically-varying microstepping
2). D Support for PanelOne and similar 20x4 text displays, not including the SD card socket - see next item. - O. Support for restore points.
- C. Predictive temperature control
- S. MQTT client - so that actions could be performed by other things, e.g lights, alarms, home automation, during or on completion of the print. So as to make things a bit more secure, the duet wifi would only want to publish data, not subscribe to anything (with the possible exception of emergency stop) Shouldn't be too hard todo as there simple mqtt implementations based on LWIP floating around already.

Just ordered mine right now…..so:
E. Support for an external SD card socket
A. Higher stepper motor current
C. Predictive temperature control
H. Grid-based bed compensation
J. Dynamically-varying microstepping -
Wow, that's a long and great list!
1 C Predictive temperature control
2 O Support for restore points
3 L Faster file upload speed
4 M Babystepping - if implanted with a usable UI
5 B Multi-threaded web server,and some comments:
re: config_override.g - smoothieware uses this and it did nothing but drive me crazy! I frequently had unexpected results that turned out to be override settings. If you do go down this path, making it editable in DWC like the config.g is would go a long way to help.
SSH would be ideal over telnet but telnet is fine for me. I only run on my internal network so security is not a huge concern. But I can see it being important in an educational and industrial situation.
ROBUST DWC connections - I know huge progress has been made on this this year but it can still improve.
-
Here's a new request: an option to perform both the auto calibration (G30 Sx) AND return the results the way S-1 does.
-
1 - predictive temp control
2 - grid based bed comp
3 - restore points
4 - dynamically varying microstepping
5 - Support for three independently-controlled Z motors -
My vote is:
- C. Predictive temperature control
- J. Dynamically-varying microstepping
- I. Faster microstepping
- M. Babystepping
- E. Support for an external SD card socket
-
Just thought of a "anything else".
Some sort of running total of print time to date. A sort of "hour meter", or "mileometer". It would be useful for setting up maintenance schedules\reminders. Like "lubricate guides" every x number of hours or "change belts" every y hundred hours". I guess this is more a web interface thing, as it would need to be running total of when the printer is actually printing rather than power on time. Just a thought…....
-
Oh yes, the hourmeter would be a very very nice feature. It could be nice to know individual axes' travel distances, as well as print hours, total powered up hours (for motors) etc.
-
Very nice list, choices, choices…
My vote would be -
-
- F. Support for multiple independent X carriages.
-
- A. Higher stepper motor current (above 2A)
-
- P. Control over which access point
-
- N. Support for driving RC servos - But do the HW on the expansion header (shield) with a +5V reg + I/O etc.
-
- R. Support to compensate for axis hysteresis
In my first week of using DuetWifi I would have voted for E. Support for an external SD card socket, but now it's almost not even something I would think about, and it's annoying that other 3D printers are still using a slow external card…
Best Regards,
Rich.

I think this is my preference of order.
C. Predictive temperature control.
H. Grid-based bed compensation,
J. Dynamically-varying microstepping
O. Support for restore points.
G. Support for three independently-controlled Z motorsI read DC42 start post that way, the other topics will
not be dropped, just come later.One suggestion from my side ( I believe the topic
was already discussed in some thread(s) on the RepRap forum)What about having a dedicated button (pin) for pausing
the print (similar the pause Web Button) ?Sometimes I have see someting strange during the print
and would like to pause. The Webbutton is to slow to reach
and a power off (like an emergency stop button)
ruins the print. -
The PanelDue offers exactly this pause button. I personally would never run a duet printer without a paneldue. It's a much more reliable and fast means of controlling the printer than the web interface. Keep in mind, the pause command does wait for the last gcode command to finish executing (or maybe even the whole queue).

I just pre-ordered a board. One feature I want to request (if it doesn't exist already) is an extruder advance (aka JKN, Linear Advance, etc) to help compensate for hysteresis in bowden systems. My machine has some very long bowden tubes and enabling this (unfinished) feature in Marlin's RC Bug fix branch made a noticeable difference on corners and top infill quality.

Good news for you. RepRapFirmware has supported extruder pressure advance for around 18 months. See

My own list for a printer:
1/ H grid-compensation
2/ C temp control with auto-tune
3/ D Simple panel
There was on forum someone asking for an odometer (recording filament consumption) and printing hour counter. That shall not be high priority, but that may be a nice to have.
The Duet WiFi having higher current capability, it can be possible to handle a CNC, but there is need to implement a few more G-Code- M0/M1 stop/start for tool change
- M3/M5 start/stop spindle
- M8/M9 Coolant on/off
- M10/M11 : Vacuum (for part maintaining) - lower priority
- Sn : spindle speed
Heaters output can be used to command SSR or to make a PWM for spindle speed control.
A 'standard' mapping shall be decided, e.g. E0 heater -> spindle on/off E1 heater -> coolant on/off , Bed heater -> Vacuum pump, Fan0 for spindle speed control.
Shapeoko is listing the G-code it is using here http://www.shapeoko.com/wiki/index.php/G-Code
