Anyway it was good to know that 4rth axis is working cause just this morning i was wondering after all the hype if 4rth axis could work at all as there was no video.

By the way i forgot to tell that all this time the 3 axis controller was loaded with the latest 4 axis software and apart from 4rth not showing on DRO, everything works fine as you know. I dont know if the 4rth will work actually but just is good to know. Anyway the 4rth axis version and the 3 axis version share same hardware.
