Duet 3 Mini 5+ : Initial announcement

@dc42 said in Duet 3 Mini 5+ : Initial announcement:

The biggest change we've made is to add CAN bus support. This places the new board firmly in the Duet 3 family, and it will allow the Mini 5+ to communicate with existing and forthcoming Duet 3 expansion boards. Expansion will be limited compared to the Duet 3 MB6HC because of the less powerful processor and reduced amount of RAM - in particular, the maximum supported number of CAN-connected stepper drivers will be
reduced - but (for example) it will be possible to connect several Duet 3 tool boards to a Mini 5+.

it supports CAN-FD so yes it will support our Duet 3 tool boards

@antlestxp Nope, I am with you brother!! can't wait.

The biggest change we've made is to add CAN bus support , now that as become useful .

We have reduced the stepper driver support from 5+3 to 5+2. T

Deal killer for me. Oh well. I was excited for this board. It was going to be the recommended board for CroXY.

@wesc

with the addition of the canbus, you can add extension board with additional steppers like this

Perfect!
That gives many new options for adaption. Even upgrading the main board to a 6HC, as one can leve the CAN based expansion boards untouched...or reuse them.
That makes it also easyer for beginners...
Start with a Mini++ and expand the hardware step by step to the level of experience...
The appetite comes while eating....

How were you using 8 motors? Dual X, dual Y, triple Z and one extruder perhaps? If so then you could put a Tool Board on the print carriage, which would provide the 8th stepper driver and greatly reduce the number of wires going to the print carriage.

@dc42 Is it possible to get my hands on a Duet3 Mini now and help with testing or is that closed?

We have a small number of generation 1 prototypes available. Our priority for those is existing and potential OEM customers. The version 1 prototypes do not support CAN, and the firmware for them doesn't include stall detection.

What's the price on them?

About the same as gold dust?

Seriously, these are most definitely not for end users, only for OEMs to evaluate. We are supplying them to selected OEMS free of charge, because will drop firmware support for them once we make the pre-production boards available. If you are an OEM, then feel free to contact us by PM or email - although I don't know whether we have any boards still available.

jallen810

@dc42 ah okay fair enough! I’m by no means an OEM. They need them due development for sure.

@dc42

are you doing an updated version of the smart effector with canbus?

Not yet. It would only make sense IMO in conjunction with a very low mass extruder drive. However, you could mount a Tool Board on a flying extruder.

@dc42
like a hemera with a smaller motor?

Yes. It would also need to be small enough to be mounted just below the effector, or possibly just above it.

Excellent decision! This is the budget but expandable board that I think many people will be looking for. I hope you order lots of them!

cabal2000

@dc42 Any news? ETA? Thanks man..

T3P3Tony

We have made some changes to the design (as @dc42 mentioned the CAN expansion plan etc) and the next prototypes are on order. I would not want to commit to a timeline for general availability yet though, still targeting November!

@T3P3Tony Thanks for the quick reply Tony. Appreciate it. Take care!!
