RPi connection option for Duet 2
I think it might be a good idea to concentrate on getting the dsf up to date on duet3 rpi first??
Duet 2 will use the same DSF as Duet 3, so no additional DSF work will be needed.

The Pi to Duet 3 interface is SPI. Duet 2 does bring SPI out to the expansion connector.
Pure speculation on my part... but I'd expect nothing will need to be removed, just hook up the SPI and run the correct firmware.
The plan in the short term is to use a Duet 2 Ethernet without the Ethernet module. The high speed SPI bus is on the socket for the Ethernet module.

There was talk in the past of adding support in RRF3 to redirect certain file system related gcodes to DSF so that PanelDue could be fully utilized with a Duet3 attached to DSF.
Is this still on the road map?
Yes I hope to implement that, but it needs support in DSF, which may not be implemented in time for 3.02.

- Triggers (M581) and wait-for-input (M587) supported on expansion and tool boards
M587 is Add WiFi network. Do you mean M577? I would very much like a 'Wait for external trigger' function

dc42,
I have an interest in beginning an effort to continue development on RRF 2 until end of life. RRF 2 in its current state is just splendid for me, and I see potential value in maintaining it as a sort of "long-term-support" firmware that users can rely on to always be available to troubleshoot or implement in mission critical machines.
Do you have any thoughts about RRF 2.0 you could document before leaving it to the community? I think you did some seriously magnificent things with RRF 2, and you seem off to the races with RRF 3. A short-medium length debrief of your thoughts about how you left it and what you may have wished to implement had development continued would be super-welcomed.
Thanks! You are literally one of the most important people in the RepRap community. I will continue directly supporting your products as long as you continue to produce them.

Thanks for pointing that out. I have corrected it.

Support switch-type Z probes on expansion and tool boards
Bit confused by this on the road map for RRF3.02. I already have the Metrol switch that I use as a Z (nozzle) probe configured as a simple switch (using M574) and connected to an expansion board. Did you mean "non switch-type Z probes on expansion boards? Or did you mean add type 5 to M558 for expansion boards?

M574 configures it as an endstop switch, not a Z probe.

I think it might be a good idea to concentrate on getting the dsf up to date on duet3 rpi first??I was referring to conditional gcode does not work on duet3 with SBC and anything regards console feedback e.g G32 does not either.

When will you have time to address the SD card connection issues with the PanelDue and Duet3 running from a RPi? Thanks

Any plans for M80/M81 support for meanwell PSUs?
I know I asked this before. Like many other. Is this anywhere on a plan? -

The idea was to keep the USB serial port free and the the SPI bus runs at 5MHz (depending on how you have it configured) and uses less resources on the Duet. Didn't make sense to develop 2 different ways to communicate between the Duets and SBC.

@dc42 Thank you. I’ve found this to make demoing our machines very challenging when taking them offsite.

TBH I'd rather have my USB port taken out byt SBC (currently attached to that USB port) than lose the ETH port by SBC (that's currently using the USB port). As compared to the setup ATTM where SBC attached to USB and ETH attached to DUET (and SBC) I will lose any outside connection to Duet2 and have USB port free.
and the the SPI bus runs at 5MHz (depending on how you have it configured) and uses less resources on the Duet.
Unfortunately, most MCU's have USB "hardware" that uses a lot of resources from MCU but I don't see how will it use more than what it is using right now. It is already implementing CDC that's one of the most resource-hungry ones.
I have zero experience with SAM's (tried, found ERRATA too late, gave up) but I doubt it's much different from STM32 so there should be 12MHz USB support out there. With all the overhead USB creates it should match the 5MHz SPI or come at least close to it. A secondary benefit would be that code on the SBC would be tad more portable as accessing /dev/tty* is much more portable than accessing (and enabling) SPI port on the expansion port of a SBC (as for e.g. one wanna use opi and not rpi or maybe fully open source ROCK pi ).
Didn't make sense to develop 2 different ways to communicate between the Duets and SBC.
That makes sense, but duet3 have USB too IIRC. Anyhow, decisions are already made, so I'll shut up now
-
The Duet2 does actually have 2 additional SPI ports on the temp daughterboard and 50pin connectors but based on @dc42's comment above, maybe he thinks they won't be fast enough.
