Duet 3 3HC Expansion board firmware update.

CSLTM

Hi,

I've managed to install the new V3.3 firmware on my Duet 3 however my expansion board is on V3.0.

I've tried moving the updated firmware for the expansion board onto the SD card however the option to install it doesn't come up like it did for the toolboards.

Any help appreciated.

Many thanks,

Tom

@csltm use M997 Bx where x is the CAN number

Hi Jay,

Maybe that didn't quite work.

The only thing that the expansion is running is the tool pin for the tool changer mechanism.

These are the errors I get, I'm still unable to home 'C' which is what that pin is called.

Cheers,

@csltm yea, looks like the expansion board hasn't been upgraded.
Which command did you send?
Is it on CAN address 1?
Whats the output of M122 B1? (assuming 1 is the CAN number)

I sent M997 B1 and upgraded the board to 3.2. Couldn't find a bin file for 3.3 expansio board firmware.

The results of M122 are as below.
