Duet 3 Mini 5+

sigourosandreas

Hello,

I am interested in buying the Duet 3 Mini 5+ and 3 or 4 Toolboard 1LC.

It is not clear for me if I can use 4 Toolboard 1LC with mini 5+, or even if I can connect them through the Duet 3 Tool Distribution Board.

So how many Toolboard 1LC can mini 5+ take?

Thank you.

I don't believe the number of expansion boards has been explicitly stated anywhere.
To use more than one toolboard you would need the distribution board.

The limit will depend on how many CAN expansion boards the Duet 3 Mini has enough processor power and RAM to support.

Currently the firmware limits for the Duet 3 Mini are 4 CAN-connected expansion boards with up to 7 drivers total on them. I can easily increase the maximum number of CAN boards if necessary, provided they don't overload the processor. If only one tool board will be used at a time (e.g. on a tool changer), that will help because a tool board that isn't moving needs very little main board processor resource.

The Duet 3 Mini can be used with the tool distribution board if you make up a cable with a 2-pin Molex KK connector at one and and RJ11 (6p2 or 6p4) connector the other end. There is a photo of this cable at https://duet3d.dozuki.com/Wiki/CAN_connection.

@dc42 ok thank you.
In fact I was thinking of using the 4 drivers on the board for x, y, z and c axes. And the Tool Distribution Board for the 3 or 4 extruders.
As you mentioned, it should be easy enough for the processor to work this way.
