Duet 3 Mini 5+ : Initial announcement

dc42

It's only green because green prototypes are sometimes faster to get made and delivered than blue ones.

@dc42 Want one for my Delta time it had an upgrade lol

dc42

So far, testing shows that the wifi upload speed is about the same as the Duet WiFi, and the Ethernet upload speed is a little faster than the Duet Ethernet.

@dc42 I assume that the SBC support is there as that would be the way I would want to run it failing that the ethernet one would be my choice TBH. Once it is available.

Looking good!

SBC support is included, but not tested yet. I've currently disabled SBC support in firmware, because I identified an issue that causes problems when SBC support is included but no SBC is connected.

Is that across the whole duet3 range or just the mini due to the different MCU?

jbarros

This would be great to test on an IDEX I'm building
You get picked for the testing or will there be a way to apply?

@dc42 There is a big difference of speed between wifi and ethernet speed ?

No, the Ethernet is currently only about 20% faster than the WiFi, although there is more scope for improvement with Ethernet.

I already have a Duet 2 Wifi. I would love to test this on my Delta, and Folgertech FT-5, that is likely going to be converted to corexy.

This looks awesome! I am especially interested in being able to use my 24v PS and then use 12v fans as they're so much easier to get ahold of!
Was the rumor I heard that Duet3 Mini will have both Ethernet and WiFi, true as well?

dc42

There will be separate Ethernet and WiFi versions.

Veti

this is a very nice evolution.

any news on when it will be available?

T3P3Tony

@Veti I expect we will have some availability for normal purchase in November.

We have to iterate on the prototype and then conduct more CE and FCC testing before we put it on general sale.

We are excited to officially announce a new Duet Mainboard:
The Duet 3 Mini 5+ is an evolution of the Duet 2 Maestro

Have you also plans to bring Duet2 WiFI/Ethernet to the next level?
For the next project I need 9 -12 steppers....

As a user of a Maestro the Duet 3 Mini 5+ would fulfill all my requirements...except the count of steppers...

@dc42
Are there any options to get 9 steppers working ???

The Duet 3 Mini is intended to fit in the medium price and performance segment, so the microcontroller doesn't have enough I/O pins for 9 drivers. However, we're looking at adding CAN bus expansion to the Mini 5+, which would allow tool boards etc. to be connected.

T3P3Tony

@DIY-O-Sphere also, you can use 12 steppers on the Duet 2!

@T3P3Tony
I know...that was an option I was thinking about.
I will build the machine in autum. If I'm able to realise a working tool lock mechanism driven by a servo, the Mini 5+ is still an option.
Locking at the IO Pin table it should be possible to drive additional servos.

T3P3Tony

@DIY-O-Sphere you can drive small hobby servos from the IO conenctors
