Hey Matt, I don't know where you are at with the retrofit but I thought I'd share some info about mine as it may help you.
I've just got the X axis going using closed loop to the controller this weekend. I am setting this up with Riocore, there is a very long thread on this forum about it, I'd recommend having a look.
I am using the original brushed DC servos, I removed all the resolver and tacho generator bits out from the end, mounted a perspex plate and fixed a CUI capacitive encoder. I did build my own H Bridge and controller board, had a couple of issues but it is now working.
The actual part doing the tricky stuff is a $30.00 fpga board (Gowin Tang Nano 9K)
There is something about turning the servo by hand without the motor drive engaged and watching the DRO update on screen!
Cheers.
Russell.
