SV: is my software stable?

Hi!
I am running DeskNC on my step/dir servosystem from Dan Mauch.
I am running at a speed of 4000mm/min that is 157ipm.
I have been running files that takes up to 3 hours to finish and without errors.
My machine is a 133mHz Compaq notebook.
The resolution is 2000 pulses for 10mm (~3/8") or 200 steps /mm.
