Adding a +1 from me. With the new Voron Extruder the Stealthburner hitting RC1, this design is largely finalized and will be released soon. The Duet 6HC & Toolboard combo makes a very good setup for this printer with the features it has. It also eliminates the need to send 20+ wires through 3 x cable chains to the tool head with the can bus. That, and Thomas Sanladerer built his Voron 2.4 with a Duet meaning his 417K subscribers got to see that build. Almost half a million people viewed his Voron videos using a Duet by the stats. I am sure there are a lot of people buying into the Duet ecosystem for this printer just from these videos alone so perhaps if the full Voron 2.4 isn't supported because of neopixels on the tool board then I think there's a compelling reason to add it to the firmware. @dc42 would you have any thoughts on this?

@phaedrux I did find the datasheets on both, you can find the info on the links below. From what I can tell they very similar, the pinouts appear the same but the 5160 has a built in motion controller so I am not sure how much difference it makes.

I'm sure I've missed the explanation somewhere but I did search.

In the product pages most of the Duet 3 boards list "On-board stepper drivers 6 x TMC2160 or TMC5160" as the drivers. Are these drivers essentially identical for the purposes of the board? did they change with a revision? I'm Just curious what drivers would come with a board if I were to order one.
