Duet 3 demo at TCT

@brunofporto sounds good, however it's likely that a farm bot would work great with Duet 2 unless you planned on having lots of heads!

@t3p3tony The issue is the size. We would like to design a polar system, with a Delta as "fine" tool manipulator to compensate for the imprecision of a 50m radius woobly thing

So a duet3 main would control the big polar system, pumps, feeders, etc. Then a add-on card would control the local precision tool.

Currently the DWC runs on the same CPU on the Duet that also handles everything else the printer has to control. It used to run on the even slower wifi chip.

Duet 2 = 120MHz 32-bit, ESP8266 = 160 MHz 32-bit.
I think moving the web task to the main Duet 2 chip was because there is no ESP8266 in Duet 2 Ethernet.
And in terms of performance, that is a mistake, because the main chip has realtime tasks to do while ESP8266 is mostly idle now.

No, the main reason we moved the web server to the main processor is because it was too hard to debug the web server on the ESP, and because of the closed source SDK for the ESP we could never be sure whether CPU time used by the web server was impacting on the WiFi performance. Also it was taking too long to upload DWC to the ESP during manufacturing.

Like most users, we run the ESP at 80MHz, not 160MHz.

Sounds really exciting. Do you have a timeline for when beta or first retail will be available?
I would like to be on the list of Beta Testers if it is possible

@percar we want to have some initial production boards in Q2 2019.

You have a great sense of humor!

Hi,

The new design looks very well thought out.

It's a good thing it is not going to be around until next year - gives me time to come up with the reason why I have to have it - it's a "wife" thing.

@t3p3tony Hey, so how close are you guys to that Q2 2019 goal for early production boards? Can you take my money for it yet?

Would it be possible to make an expansion board that mounts directly to the extruder? Say it has a single stepper driver, some PWN fan controls, Z probe input, heater control and a thermistor input? Would be really nice if all you had to run to the extruder is power and data, instead of having a mess of wires like normal. Would also make tool changing much easier.

I think they've actually talked about a board exactly like that.

dc42

It will be a smart tool board, handling at least an extruder motor, heater, temperature sensor, 2 fans and a Z probe.

I do have a Duet 2 - I don't need a Duet 3 - I do have a Duet 2 - I don't need a Duet 3...

Just practicing. I need to get this mandra working until Duet 3 is available.

I was testing the Duet 3 second prototypes earlier today.

what are the main cool features, compared to DuetWiFi ? will you uncover a bit?

@c310 That link works for me.

Manuel, - it's "mantra" not "mandra" (that's a town in Greece). Oh and it's "practising" not "practicing".

Here endeth the English lesson for today

wilriker

@deckingman Yeah, the mandra-mantra thing is the same in German.

But with "practicing" I can - for once - correct you. This is the valid American spelling. And since I usually also write "color" and "honor" I consider this correct.

deckingman

@wilriker I gave you an English lesson, not an American lesson. They drive on the wrong side of the road and use all the wrong words for parts of cars (trunk instead of boot, hood instead of bonnet etc).
