Duet 3 Mainboard 6HC - initial production run.

Selecta_Mota

Any news on the ToolBoard?
Would love to test it with my new printer and Hemera

@Selecta_Mota I expect we will announce the production pre order before Christmas for shipping either end of Jan or beginning of Feb.

@T3P3Tony and now I'm going to have to order one of those too

Selecta_Mota

@T3P3Tony great to hear, thank you

@T3P3Tony So Duet 3 is out. when is the expansion board coming out for the external stepper drivers? As I understand 3HC board still doesn't support external stepper drivers and/or servos.
It sounds a bit one step forward two steps back with a loss of the external stepper driver support.

A somewhat uniformed post that makes no real sense if you look at and understand the road map of what the duet team is preparing they have already given info on when the expansion boards will be available. (pre order is open)

@CaLviNx I think the key words in @Aurimas post were "external stepper drivers".

We finalised the tool board design and ordered the PCBs last Friday. We're now working on the single-external-stepper board, which is very simple because it is essentially a cut-down tool board. We are aiming to order the PCBs for them in time to get them before Chinese new year (25 January). We have already tested prototypes made from hacked prototype tool boards.

Yes I know what he meant. You of all people should well understand that is not the main priority/direction that the duet 3 appears to be travelling at this point in time, but as I already said all info has already been stated, one step at a time

@dc42 any news on the toolboard?
or are you also affected by corona?

dc42

We're not affected by Corona yet. Tool boards are in production and should be listed very soon. Tool distribution boards will follow shortly.

@dc42 Do I need the distribution board if I`m going to use only one Tool Board?
Does the toolboard include wire terminals for the CAN bus (+ the other not using screw terminals) wires between the ToolBoard and the Duet 3?

The distribution board is optional. It provides a convenient way of providing individually fused power to up to 4 tool boards, converting the CAN cable from RJ11 to JST ZH (because RJ11 was too big to fit on the tool board), and terminating the CAN cable. Without it, you should provide your own power fuse (e.g. an in-line auto fuse) and terminate the CAN bus with a 120 ohm resistor unless the bus goes on to an expansion board.

Any price info on the distribution board?

I may order ToolBoard + distribution board - so I`m ready for more projects in the future

dc42

Provisional price for the distribution board is £20 ex tax. This includes connectors, fuses and probably a 0.5m CAN cable. We plan to offer a £10 discount on orders of 4 tool boards + distribution board.

mundsen

So then I can install the distribution board at the printer top-right side (A) and the toolboard at the top of the hemera (B) ?

droftarts

@mundsen If you only have one tool, you don't need the distribution board.

Stop teasing us, take my money and ship I need a Homer picture here.....

@CaLviNx Agree - ToolBoard is the missing part on my printer

@dc42 Are there any concrete plans on implementing an EtherCAT-master? If yes, until when and do you plan to do an own implementation or use something like https://github.com/OpenEtherCATsociety/SOEM

Btw thanks for that great piece of hardware/software!
