Hi, I bought an Asus P5LP-LE MB. I want to use this for emc2. My machine is a a milling machine with DC servo motors. I am going to replace the Heidenhain TNC 151 with the emc2 control. I have been running the latency test on the MB. The best I have been able to do when running the test for many hours (2h to 8h) is: Servo Thread 14602 nS max jitter Base Thread 18487 nS max jitter.
My understanding is that these numbers should be good for use with servo motors. When running the latency-test I also ran glxgears, firefox looking at youtube videos, view jpg pictures resize, minimize and restore windows etc. There is just one area of concern. If I also open and view an .avi file the jitter jumps to a huge number (like > 200000) when the .avi window is opened or closed. Otherwise the numbers above are what I see. Should this really be a concern? I don't plan on viewing .avi files when running a cnc machine. I like this MB because it has 3 PCI slots so thee is plenty of room for expansion. I plan to place the latency-test results in the wiki.
