Duet 3 Mainboard 6HC - initial production run.

dc42

Yes, potentially. We're already planning a WiFi version of the Maestro, so we can look at doing a variant to connect to a Pi instead.

@t3p3tony I did order this one (model B) for the DUET 3/pi4 - seems like an ok capasitive lcd with high brightness

The new home for my Duet 3 + rpi4 + 7" LCD (design in progress)

Hi, anyone know if it’s possible to add an extra stepper with for example a TB6600 to the Duet3? And is it also possible to get in queue for the 3HC expansion board?

T3P3Tony

@hanshogeland at this stage the main board we are producing initially (6HC) and the expansion board we have in prototype of (3HC) do not have the interface for external drivers. That said we plan an expansion board for external drivers as soon as we can. (but I can't commit to a date yet!). Further out I think there will probably be enough demand for a main board that has no onboard drivers and just uses external drivers.

I expect to announce more about ordering expansion boards as soon as we have completed some more testing on the prototypes. The production boards will have some (relatively minor) changes from the prototypes, but we need more testing to confirm we have identified all the required changes.

@t3p3tony thx for the quick reply, yes we are eager to begin our journey. I need atleast 13 drivers so the Duet 3 is the choice

Sorry to be a pain.. but if you are including a ribbon cable to go between the Duet 3 & the SBC do you offhand know the length of the cable that will be included ?

Im designing plate mounts so i can have the SBC side by side with the Duet so a cable length would be handy to know.

Hi!
I`m trying to install the duetwebserver on my RPI 4

Is it possible to test/start it without the Duet 3 connected to the PI?

wilriker

@mundsen Not really. It requires a connection to DuetControlServer to start up properly and serve requests. And DuetControlServer won't start unless Duet 3 is connected.

mundsen

@wilriker ok, I`ll have to wait for my Duet 3 to arrive then

@dc42 , I currently have poor wifi connectivity to one of my duets (signal is great but my laptop gets around 50Mbit in the same place as the printer). I am acquiring a RPi4 next week, would it be feasible to hook it up to a Duet 2 Wifi? (I suppose I need to remove the wifi module?). And as I understand it, DSF only supports Duet 3 but it will support Duet 2 in the future, right?

dc42

@whosrdaddy, did you mean "signal is not great"? If so, and you are capable of removing the WiFi module without damaging the PCB, then your best option is probably to replace the WiFi module by the ESP-07S version and external antenna.

There is no firmware build for Duet 2+RPi yet, and it will be at least a month before I can consider doing one.

Planning my Duet 3 setup. Can Duet 3 power an rpi4 + 7 inch LCD + USB camera ++ ?

@dc42 said in Duet 3 Mainboard 6HC - initial production run.:

ESP-07S

Thats the 4MB flash version, is that a requirement for the upgrade? Might be worth highlighting that

TLAS

@mundsen
You could probably do the math by finding the amp usage of each component. WhenI ran it to determine the maximum number of LEDs I could drive while using a 7” screen and it came out to about 10 when considering the load of the PI + LCD screen. I’m going to use an external power source for the PI (and connected components), and leave the PI in always-on mode. Then have a separate power button to boot up the Duet 3 and the rest of the system.

A Former User

@tlas I've got my 24V supply in series with a mains relay hooked up to a unused GPIO pin on the Pi, so the Pi can turn on/off the Duet 3. One day I'll throw together a systemd script to handle it with dependencies to DuetSoftwareFramework.

(Both the 24V and USB supply are also hooked up to a Wifi controlled socket so both can turned completely off from HomeAssistant:)

My Duet 3 order have status = Completed

Does completed indicate that it has been shipped?

There is no tracking info

T3P3Tony

@mundsen nope, shipping will start soon (this week!) The shop software is a bit poor for pre-orders

mundsen

@T3P3Tony so the first Duet 3 are fine ? Exited

Dougal1957

Tony Can you say if a connector kit will be included and also a cable for the SBC or do we need to source our own beforehand? if we do can you list what we need to obtain.
