Something I had forgotten to mention before I started this run of parts - would you consider adding a parts counter DRO? Should be fairly simple and you already have a macropump anyway so will only have to look at the Cycle button being activated and count it.
Another thing which may not be that simple is a total elapsed time DRO (from the moment Mach loads). It has to be zero-able. Together with the part counter it can be a very valuable tool for high volume runs.
