Connection between two Duet3 mini via Can

[droftarts]

@Proschi78 to have more than one controllable LED strip, and/or LED strip on a CAN connected board, you need to be running firmware 3.5 (currently beta3). Define LED strips with M950 E (parameter for LED strip number) and C (pin name, with CAN address), then control with M150 command including E parameter for LED strip number.

Firmware 3.5 is in beta, so this may not have been rigorously tested, and using the beta may cause other issues. Let us know how you get on.

@droftarts Thank you for your description

@droftarts what is the pin name of the neopixel output on the Duet 3 5+ mini M950 E0 C"?"

[droftarts]

@Proschi78 Unfortunately, it turns out I am in error. Currently, multiple LED strips are only implemented in the STM fork of RepRapFirmware, so far. There is also no way to target the LED output on a CAN-connected mainboard-as-expansion board. Sorry.

@droftarts ok that means I connect the neopixel to the master duet and don't need an M950 command?

Yes, correct. You control them with M150.

@droftarts Ok I'll test it this afternoon thanks.

Is it planned that it will be implemented to control led's via CAN

[droftarts]

@Proschi78 not in the upcoming 3.5 release.

@Proschi78 some of the infrastructure (i.e. CAN message protocols) will be in place to support this in the 3.5.0 release, but the support for LEDs on expansion boards may have to wait a little longer.
