Is this something we could add to Ioni to ease the design/assmbly of a high power drive, or am I way off track?

That sounds good; something like that would work for me if I can locate a service or person to assemble them…

A set of open-source reference boards is an exciting idea. Similar to dirty pcbs (http://dirtypcbs.com/view.php) where
– anyone can order previous designs outright,
– or make some modifications, and order the modified design while making it available to others.

except all source files are available.

A github for IONI mother boards, if you will…..

I would love to have a reference design on which to base my own boards.

Sure it’s possible to fit multiple axis on one PCB but that would grow big. The single axis alone is 160×100 mm.

If we want to manufacture these industrially, we would rather make “powerstageless ioni” which would reduce parts from the power board and make them smaller. But that of course needs volume to be cost efficiently doable. Maybe there is enough demand for such systems, we will keep eyes open to spot it :)

Do you mean it could only be single axis, or that you had only planned it for single axis?

I’d like to see a multi axis hybrid of Ionicube and Ionizer. The use cases I can see include CNC machine tools with small axis drive motors and a large spindle drive, or robotics where there may be a couple of big drive motors and smaller motors for steering or onboard accessories but all motors would use the same bus voltage.

I’d also be interested in chipping in to finance it, but couldn’t be any use in the actual design.

That would be single axis.

I believe for 230VAC the Argon drive would much easier solution. The custom board would be good filling the void of other voltage/current ranges.

I would be interested in finished boards, 230VAC if possible. Can’t help you with design but I would be interested in chipping in to finance it.
Also, is this going to be multi axis or single drive board only?

Yes, driving two DC motors would be possible with 4 power lanes but there is no enough other I/O on IONI for that (such as encoder inputs). So that is unfortunately out of question.
