Duet 3 CAN and external motor drives

[patrick802]

Hello,
What is the current state of the expansion boards for external motor drivers? I am considering using a Duet board to drive external closed loop steppers or BLDC motors. I have read a few forum postings that talked about CAN expansion boards driving external closed loop motors via Step and Dir TTL outputs and 3rd party boards connected via CAN. IIRC David Crocker mentioned something about a closed loop solution on the Duet directly.

I am planning a multipurpose CoreXY machine with a tool changer and would like to understand what is available now.

Thanks,
Patrick

The CAN connected external driver interface board is in production and we have stock.

The closed loop board is still in prototype stage.

Hi David,

Who should I contact to purchase one of these, or at least get my name on a list ?
I am working with a client who needs to drive some powerful external drives.

Thanks & Regards,

Julian.

Hi David,
The Duet 3 expansion board doesn't appear to have any logic level connections for step and dir outputs. Are you referring to a different board?

Best Regards,
Patrick

Drop me a line, info@duet3d.com

We only just got them in so our resellers have not had a chance to stock them yet.

@Veti The link to the documentation points at the tool board. Could you send me a link to that board?

Thanks,
Patrick

@patrick802
there is no documentation site yet.
@T3P3Tony can you correct the link on the duet store page?

@Rushmere3D
good catch

@Rushmere3D
thanks very much. I guess I need 3 of those boards to start with.

@Rushmere3D
The reseller links need to be fixed. I am trying to order 3 of them.
