My understanding is that the DX-32 control is 4th axis capable. I know I can pulse an indexer. What I'm wondering is how I can add a true 4th (A) axis. I have a spare control so I should be able to harvest the servo drive and wiring and add it to my machine. I then would need an appropriate DC servo drive indexer of course. Has anyone added a 4th axis to their Torq-cut?
