Duet 3 demo at TCT
-
Can someone take my money for this yet? I void every warranty I touch when it comes to my own stuff, I am COMPLETELY okay with highly experimental, hell practically describes my life XD
I don't see anything on anyone's github so I can't even pay a pcb manufacturer to make one for me on my own.
When will you take my money?

@noskillzengineer Get in the queue ...........

@deckingman and that queue is growing already lol

When the Duet 3 arrives I'm more than willing to help people dispose of their used Duet Ethernets!

Hi everybody i a building a large 3d printer but now don t know whether to wait for the duet 3 ethernet or buy the duet 2 ethernet
according to the specs pf the duet 3 seems to have some good improvements over the duet 2
what do you think guys ? -

Carlos, how long are you willing to wait?
-
well i think can wait until it s released provided it s released this year as the printer is going to be quite large around 1 meter long all sides
looking at the duet 3 specs seems to be good for large projects
but of course that s on paper because we really don t know how is going to perform against the long tested duet 2 once buyers start having their hands on them
so maybe you guys with more experience with the duet boards can tell if the improvement of the duet 3 over the duet 2 is worth the wait
thanks for your comments i appreciate it -
I'm coming from a slightly different angle on this. From a techy side I'd like to be on the current but trying to keep significant upgrades on my machines to an as needed basis only - or I suddenly become more flush with cash!
I'm running on previous generation Duets - v0.6 - with noisey Steppers and not able to use the 2.0+ firmware. That said with a cantilever other than the lack of ringing damping/suppression control I'm not getting close to the limits of the board. Through careful testing and often dragged out investigation I'm picking off issues with the frame, extruder, hotend and heatbeds rather than hitting v0.6 limits. The longer I leave the upgrade the more likely other bits will be available too, be that a responsive magnetic filament sensor that moves toward a closed loop extruder or even the duet 3s.
If you are only using single or dual extruder without mixing and the stepper motors that you have picked are within the range of the duet 2 you'd be hard pushed to hit the limits of the duet 2 in the short term as you also learn about and evaluate the performamce of the new build machine.
With a new build you've plenty of enjoyment to be had from getting that running well. Save the 'bonus' of the Duet 3 until it is needed and you will appreciate it more then when performance improvements are thin on the ground. If you go this way Duets tend to have a strong resale value on ebay, even the v0.6 boards are still strong sellers.
For what it is worth last I hearf the Duet 3 will be marketed as a premium product in the Duet family, rather than replacing the Duet 2.

thanks for your comments i appreciate itIMO the Duet Ethernet and Wi-Fi are excellent boards and will likely be more than capable of doing what you want. But it depends a bit on what size motors you think you'll need to lift a bed that big. Also a one meter square printer will need substantial rails to prevent sagging so the moving mass is going to be quite high. So I think a good starting point would be to spec the motors that you think you'll need, then see if the Duet 2 series maximum motor current of 2.4 Amps will be adequate. I suspect it will be but you need to do the calculations. If it helps, I use a single Nema17 running at 1800 mA to drive my 400mm x 400mm x 10mm think aluminium bed via 3off 8mm x 1mm lead screws and a continuous belt without any gearing. Each of my CoreXY gantries has a moving mass of about 1.5kg and these are all driven by the same spec motors.
The other consideration is the number of stepper drivers. The limit for the Duet2 series is 5 on the main board plus 5 on the Duex5 expansion board plus 2 external drivers via the CON_LCD connector. The Duet 3 will support more stepper drivers via Can Bus expansion boards. AFAIK, the main board will have 6 drivers and each expansion board will have another 3. I don't know if there is a limit on the number of expansion boards but I do know that the expansion capability will allow for many more stepper drives (which is good news for me because I have an immediate need for 13 and a future need for a few more).
One final point that is important to me but may not be for you, is that with Duet2 series, all the wiring has to go back to the main board or the expansion board which has to be located very close to the main board. In my case, I have 5 extruders on a moving carriage so that's 20 conductors. Plus all the other wires for the hot end (heater, thermistor, end stops, Z probe, lights, part fans, hot end fan etc). So that's something like 40 conductors that have to go though a cable chain and the be routed in and around the frame. Duet 3 will give me the ability to mount 2 expansion boards on the upper carriage, close to the extruders so I'll only need 4 conductors (2 power and 2 data) going through a much smaller cable chain.

@deckingman thank you for your response i apreciate it the printer will have two extruders and i
ll be buying nema 23 24v 3a theyll be 5 motors plus the extruder s if i go with the duet 2 ethernet it will be with the duex5 expansion board too . What i read is that the duet 2 soport these motors
looking at the duet 3 specs it can soport these motors with eas -
@doctrucker thank you for the response I`ve been reading that the duet 3 is expected to be released on q3 this year
but that s not for sure it could very well be released at the end of the year or even the next one, who knows
now i think i am kind of thinking going with the duet 2 -

looking at the duet 3 specs it can soport these motors with easI think you'll be fine with Duet 2 series. Running 3 Amp steppers at 2.4 amps would be ideal. If you only have 5 motors plus 2 extruders, you could consider using the Duex2 expansion board, rather than the Duex5.

well i think next week i ll be ordering the duet 2 ethernet thank you for your comments
-
i would be interested in a very rough information about the price of the base unit.
obviously it will be more expensive than the duet 2.
is it between the duet 2 and twice the price of the duet 2? -

Will you guys take my money and give me a Duet 3 yet?
-
@noskillzengineer we are definitely getting closer to taking orders for the pre-production run but we are not there yet!!
-
Will RRF contributors / UI developers get priority so we can "test"?
