Machine is still tight. Backlash is great on this machine.
I had search the forum for past postings and someone mentioned that the look ahead buffers will fill and on long runs, or really tight corners, you will see it stop, go , stop, go again. I get that on exactly long runs, and tight corners. The 1400-4 is a 286 microprocessor, and the 1400-5 is a 386SX, so the -5 stuff will surely process and have better look ahead buffers.
EDIT :
Avoid another post....
I was just running a chamfer bit around an edge and the buffers were running about 15 and the jerking was pretty bad. However running a .625 around a block of alum the buffers were running about 52 and there was no jerking at all. both code came from MasterCam. What sets up the buffer look ahead? Why 15 on one of the paths, and 52 on the other?
