Got the solution. In the new setup I'd set the kernal speed at 35000. I just ran a test with it set back at the normal 25000 and the speed mismatch got fixed. Is it safe to assume my computer's not powerful enough for maxium performance. Its a pentium 3 666mhz. What would I gain, percent wise, by swapping the box for a faster one? Does the driver play a role. My driver is a 10 year old Camtronics servo driver. Its been a great dependable unit but never-the-less long in the tooth.
