Frankly speaking, if I would start this project today, I would definitely go other ways in some decisions - the main mistake I've done was trying to use drive and electronics of the original design. It would be much simpler and functional to drop the original electronics and spindle drive and replace it with a powerful stepper drive - there are Nema 34 motors with virtually same size and power as the original DC drive. The control scheme would me trivial in this case, as well as the significant increase in functionality could be achieved.
