Duet 3 release date

I foresee the largest "con" as being the boot up time.
I don't think this will be the case, as RPI is a computer without an OS, the OS you have to provide (usually a variant of linux which boots slownly by comparison to RTOS), If you load the reprap RTOS on it then it will be as fast as (actually faster because the more powerful cpu) the current duet2. Please correct me if I'm mistaken.

@denke Looks like it will run duet3d software on top of linux. See here for prototype details, although this may not all apply to the final product: https://duet3d.dozuki.com/Wiki/Duet_3_prototype_guide_for_OEMs.
I imagine that it won't be necessary to restart/reset the raspi frequently. Boot times on a stripped down raspi install are only a few seconds in any case.

The RTOS that forms a chunk of RepRapFirmware is a really stripped down OS that I believe provides threading capability to microprocessors. I also think it is aimed at the Sam ATMEL processor that runs in the Duets.
CAN was available on the old Arduino Due. I wonder if there is an opening for people who want the practicality of local stepper control but don't need the real time processing clout requied for 5+ channel mixing. In other words a version of RepRapFirmware 3 configured to run all axis through the CAN bus. I'd be interested to hear if there were performance reasons for that architecture not being used rather than the cost to set up your standard machine.
Edit: I'm not suggesting we cram RepRapFirmware 3 onto the Due, more like the Ada Fruit Grand Central which I believe is Due format but with a very simialr processor to the Duet 2 boards.

@deckingman surely you can "cheat" and get started on RRF3 with the Duet 2 hardware, and even start the re-wiring before you get the Duet 3 hardware? Trade off would be longer downtime, but maybe worth it?

This is getting a bit off topic but ...........
I'm doing what I can. One thing that's a bit of head ache for me is that in order to get the printer through the door of my study, I have to break it down into two sections. Mechanically, that's easy to do - just 4 bolts. But as things were until a couple of days ago, there were a lot of cables running between those two sections. That was a bit of pain the last time I took my printer to the TCT show so in order to mitigate that, I've moved all the mains wiring, PSUs, SSR, etc. That was all at the bottom of the printer. Now it's on a new aluminium plate fixed to the top section, closer to where 3 of the boards will be fitted.
Like this
But I need to keep the printer running in order to make new cases when the the new boards arrive. So the rest of the wiring now looks like this
The new extruder gantry to take 6 extruders and two expansion boards is finished (just hope the boards fit).
Like I said, this is getting way off topic and I shouldn't really be posting these pictures in this thread. So, if you really want to know how things are progressing, take a look at my blog (link in my signature). As well as Duet 3, I've done few other upgrade and have a couple more planned before the show.

Hi any updates on a round two of duet 3 sales? I'm only waiting on this last piece before I can get printing

@elmoret yes that does help! Thanks for the heads-up!
-
We're currently planning to open a pre order for the next batch next week. Delivery is expected to be in November.
-
Just to confirm, we will be releasing the next batch to preorder the back end of next week, targeting a delivery schedule of November. This will be a larger batch and should see the Mainboard transition to a "normally in stock" product.
I realise that the slow ramp to general availability is frustrating people who want to get their hands on one ASAP. We are ensuring we learn from the ramp up on Duet 2 and have things "behind the scenes", like Automated Test Equipment, in a good place.

@T3P3Tony ATE?

@T3P3Tony Cheers!
-
@T3P3Tony so after the New Years you will work on major updates to the Duet 2 line of boards?
-
@T3P3Tony still planning to have pre orders this week?
-
@thebeachtoday putting it off to next week to ensure we have all our ducks in a row!
-
@T3P3Tony how are things looking?

@thebeachtoday Pre orders are open. See this post

Will there be a wifi version of Duet 3 soon? Then I could upgrade to Duet 3.

Duet 3 is intended to be used with a Radspberry Pi (RPi) or other single board computer (SBC), although it can also be used in standalone mode using the built-in Ethernet port and SD card. The RPi provides both Ethernet and WiFi. So we don't plan to make a version of Duet 3 with WiFi on board.
