Greg, thank you for your very educational post. I would loved to get a copy of the factory manual and I can pay you for any expense involved in copying it etc and for your time. I read a bit about M functions and it seems easy to use, though it would be a true 4th axis. I will try to get it to work with my mill. Do you happen to know what Amphenol connector do I need for this one.
