Thanks for the replies Martin, Mark, Jon. Since I disabled the screen saver, the screen stays up and appears normal, axis motion stops, spindle and mist remain running, the AXIS program stop button is depressed as if in normal manual mode. It's almost like a feed hold, now that you mention it. I'll have to check this out. > Ninteenth hole?

(I am > assuming this is NOT one of the machines with a UPC board > in it?) I am using using two dual port parallel PCI cards, not a USC (servos are planned ,but don't know when). There are a lot of unused pins open. I think the parallel port pins are biased on the card normally. The .hal file has very little done beyond the basic stepper configuration ( except the DAC, MPG and disabled Charge-pump <-? ). I'll clean up the .hal and try again. Mark: "I'd try to do away with cutting most of the slots that you know work, to reduce the wait if nothing else. Looks like that can be done by changing line 57 from #10=0 to #10=17 . " Good point, easy to try, thanks. Martin: "Before you go there looking have a look at "power management", I think that's off the "Preferences" menu on the desktop, from memory that gives you some access to how soon things start throttling back when the PC is left to its own devices. Maybe something else to try before you start tearing your hair out? " I'm not so proficient with the BIOS and background settings because I seldom have to deal with them. I guess it's time to reintroduce myself. By the way, most of my hair was gone a while ago, so I have little to lose. Also, after I swapped the PC, I ran the latency test, found that the pesky pcspkr module needed to be removed, then ran for an hour with ~9000us and ~15000us for jitter. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
