Duet 3 release date



  • Can you give an estimate when V3 will be released



  • +1 Been wondering as well. Ill risk the wait for 3, but need to move on if 9 months. Pleas give us all a hint if you can.
    And for us US folks, how long will the stock take to float across the pond? Please consider the possibility to allow direct orders for some short window?
    Thanks!



  • I would imagine that this is an impossible question to answer at this time. In another thread, it was mentioned that some prototypes would be produced in Q2 of this year. As they are prototypes, then they will need to be evaluated. The result of that evaluation may or may not mean that further revisions are necessary. Also, my understanding is that Duet3 will consist of a main board plus a number of expansion boards, all of which will need to be evaluated and possibly go through some sort of design revisions.



  • I'm more interested in what the interface specifications are (e.g. CAN bus) so that extensions one makes now are compatible with Duet 3.



  • @joergs5 I'm fairly sure the Duet guys have already said that it's CAN bus and in another thread, it has been stated that the number of conductors for expansion boards will be 4 - 2 for data and 2 for power.



  • @deckingman I meant which CAN bus version. CAN FD as I understood, but which specific version and for what. Best would be to know which interface CAN chip is used.

    No idea - I'm just an end user like you.



  • @deckingman I know, but if you say you are only an end user is (british?) understatement 😉

    I'm not sure I understand. Perhaps something got lost in translation. What I mean is that I am not part of the Duet team and so they don't tell me anything that they wouldn't tell any other user. I have no "inside knowledge" of their plans.

    Status of the Duet 3 project:

    • The first prototypes were a technology demonstrator, so that we could gain experience with CAN bus, the the new processors we are using, and the new stepper drivers. We demonstrated them at TCT last year.
    • The second prototypes of the main boards are intended to be very close to the production design. We had some assembly issues related to the new stepper drivers, which we are working out with Trinamic and our PCB assembler. Several of the prototypes are working well and have passed all tests so far. There is one functional unit remaining to be tested, which is waiting for software. When that has been tested, we will ship some of the prototypes to OEM customers who wish to integrate Duet 3 into their designs.
    • The second design iteration of the expansion board has started. The functional changes from the first prototype are small. We expect to order prototypes soon.
    • Design of the smart tool board is on hold while we wait for our OEMs to specify their requirements. It is essentially a cut-down expansion board, so it won't take long to complete. I expect this is something we will customise for OEMs, because one design is unlikely to suit everyone, especially given the space constraints for a board mounted on a print head.

    I expect us to be shipping Duet 3 main boards and expansion boards in Q3 this year. But of course that is subject to receiving good feedback from our OEMs and other beta testers, resolving the assembly issues, and not coming up against any other issues that we are not able to resolve speedily. Availability of Duet 3 in the US and mainland Europe through our distributors should be only a few days later than availability in the UK.



  • @deckingman I only meant, you are not a normal user, but one of the best. This comment had nothing to do with duet 3.

    Thank you David for your detailed information!



  • Excellent detailed response David; tip of that to you for sharing. Development is always a guess (and usually a little longer than planned) so you have more or less helped me to decide on a Duet 2 for now ....I however will be lurking and watching progress closely and wish you guys luck on successful designs and testing.



  • Any news about the Release Date?



  • IIRC, I read somewhere here that Duet 3 will not be a stand alone controller and will require an additional single board computer to operate, and that it is not positioned to replaced Duet 2 but to be a higher end alternative for certain use cases.

    Is it so?



  • That tracks with what I've been reading. The early prototype giveaway is a special version that was made for stand alone use, while the next ones are designed to use a Raspberry Pi for networking etc.



  • If that really is the case, comfort would be a real step backwards.

    Because as I understand you now rupture then a Raspberry to the Duet in the domestic network to find and control ... Did I understand that correctly?



  • I can't say what you wrote made a whole lot of sense to me, so hard to say; but I believe the limitations of the ESP8266 is the reason it will be replaced with a SBC like the Raspberry Pi.



  • Hmm ... Well then let's surprise ourselves.
    Do you think the expansion board for the network is offered directly by Duet, or do you have to "tinker" yourself?



  • Time will tell. I just don't see the problem - the customers why buy just the Duet board are likely comfortable with building, wiring and configuring a 3d printer from scratch ... adding a Raspberry Pi isn't really increasing the complexity by much.



  • This is the statement I was referring to earlier, which indicates that a standalone Duet board will still be available though with limited software updates.

    We expect Duet 2 to continue to be mainstream for most applications and we will continue to make minor improvements to the Duet 2 series.
