I ran a two hour 3D job today with all axis running fast and the tool came back to the start fine and did not seem to loose position.
One thing I notice though. the DRO's are slow to enter values - about 2 or three seconds before they appear - sort of sluggish - and when the machine is running they are just frozen - dosnt seem to matter in practise, but it is a bit disconcerting.
Would that be Path Pilot or my computer?
