The idea is to put a much heavier load on the computer when testing, so you identify and correct any potential problems before you start losing parts due to errors you didn't see (in "light" testing).
If you might plan to leave EMC2 running overnight (on some long G-code program), then you should probably let the latency test run overnight. There are background tasks that run from time to time (updating file indexes, for example), which would usually not be a problem, but could be if you leave the machine running when they happen. The reason to stress the machine (with disk, video, network, and USB activity) is that those are common sources of problems. There are also things that are unrelated to user activity which could cause problems, and which may not be found in a 5-minute run of the test. The fact is that we don't know all the possible causes of realtime problems, so we can only say that you should test the things we know about, and leave it running long enough that you're satisfied that your machine doesn't have any (significant) unknown problems lurking. - Steve ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
