Mine certainly had an image on else I would have been lost as I know very little about the way Linux interacts (I know a lot more now since I got this thing on Saturday)

Did the Duet 3 just get classified as a "gateway drug"?
-
@Danal it should have had the image, glad you got it working!
-
@T3P3Tony Have you guys tested to determine the maximum practical SPI clock rate the Duet3 can handle, irrespective of cable characteristics?
-
@gtj0 it is determined by cable length. With the cables we supply we expect at least 10Mhz will work well, Iam currently running 5Mhz with no issues and after TCT will try extended periods with 10Mhz.
The image comes with 1Mhz as a default - thats conservative but till allows for a high throughput.

Tony,
I despise bothering you like this, but is there any news on any units being available? I've got cash in hand, and this would be PERFECT on the rig I am putting together!Doug instructed me to come bother you.
Thanks!

Current plans are to ship the next batch in November, following EMC testing for CE/FCC certification and any resulting changes we need to make. We were planning to open a pre-order for that batch next week, but that may be difficult because of the TCT show.

Received my Duet3 today......looking at this up close for the first time, as couple thoughts come to mind.
(1) it's bigger than I expected. I actually prefer that it is a bit bigger because it gives the impression of more of a "motherboard" or "mainboard" which is what I wanted out of the Duet2 initially.
(2) there are two different type of headers on this, the motor headers are significantly "beefier"
(Kinda wish they were the same like tan-ish color though.....first world problems
)(3) lotta components on this board....getting me excited and I haven't even plugged it in yet!!!
(4) there's two RJ45 ports on it?? Hmmm, okay, cool.
(5) kinda wish someone would hit these with a fine file, knife, or like red or blue scotchbright before they got sent out, I have it here, I just wish I didn't have to, again, first world problems.
Excited to use it!!!
Thank you!

It should have if it didn't

Thank you!x2 RJ 45 port's ?
I received mine today and I thought it was an RJ45 & an RJ11
-
Should be a RJ45 (8 pin) for Ethernet* and a RJ11 (6pin) for the CAN bus on the production board, but at a glance they look somewhat similar

There was a blog some time ago how to destroy a Duet 2, information how to avoid it. I would find it helpful to have the same information for the new Duet 3: what should one avoid in any case (wrong voltage at pin x/connecting pin x with y, connection cable etc.). It can be a short list which can be print out and hang it over the board while one wires it up. A cheat sheet with a caution list and the Duet 3 board as image with the dangerous places marked red.

Does the Duet3/Raspberry support USB Camera (connected to the PI) for integration in the Web interface?
I have a Logitech 1080P USB camera - possible to use? -

We've tried to make the Duet 3 even tougher than Duet 2 by including additional protection mechanisms. In particular, it's designed to survive a short between the external +5V and/or +3.3V rails and +24V. But I haven't tested these protection mechanisms yet, because Duet 3 boards are too scarce to risk writing off.
One thing we didn't include protection against is reverse polarity VIN. So be sure to get the polarity right! If you get it wrong, then the board may survive, depending on the short circuit current of the power supply. I "tested" reverse polarity a couple of weeks ago and the board was OK afterwards.

I have a Logitech 1080P USB camera - possible to use?I'm not sure whether this is implemented yet, but if not then it certainly will be. We chose a dedicated SPI bus for connecting the Pi to the Duet so as to keep the USB subsystem free for high bandwidth devices such as cameras.
-
One more thing - should I get a speaker for my PI? Does the web server use sounds for warnings, autolevel ready..?
-
@mundsen it does not currently
-
-
@CaLviNx I know you can use a USB camera in combination with the pi - but the web server need to support/use it to get video in the duet web interface
-
@dc42 Thank your for your information about what to avoid.
-
Was it an RJ11 port??? Whoops! Clearly I didn't look at it particularly closely
My bad!!!
