Awesome! Thanks!
So, now I'll see about getting my hands on a stmbl drive.

That's the hard part, as one of the ICs that the drive depends on (the big expensive one) is no longer available.

There is an STMBL chat forum here, where you might find some advice.
gitter.im/rene-dev/stmbl

I know,, I have already posted a question on that chat, but no information has come forth there. As great as the stmbl drive looks, I find it very difficult to get specific information as the developers seem to have the drives they needed and life moves on.
It looks very impressive and is apparently able to interface with my 4-wire RS422 Mitsubishi serial encoders but apparently the master firmware supports only the 2-wire Mitsubishi encoder interface and I have not found out if I could get the 4-wire version anywhere.
And then of course there needs to be a new layout for a new IGBT which could be done next month or next year or never.
So I'm looking for alternatives.

your encoders will work fine with 2-wire connection

So after weighing my options I finally moved forward with this robot and it's broken controller. Since dm17ry is an expert on mitsubishi drives and motors and has some pretty awesome insights in the technology used I was able to get the servos running with some used mitsubishi J4 drives.

The original controller:



Had some PCBs made up to interface the drives with the original connectors:



And in action:
