someone suggested i follow an XP cleanup routine on the documentation page of the Mach site. I looked over the page briefly and now that I have time to try and work through the list, I can't find it. In fact, mention of the list seems to have been removed from the response to my question. Can someone please let me know what is going on?

thanks everyone for your input! I've got a pretty good to do list going now and I'll just start my way working through them. For now I'll slow the machine down. And start cutting parts. One last thing though. Will do you think these out of sink pulses will result in missed steps and a loss of accuracy on a long program?

thanks

It's a HP dx2200, The processor is a pentium 4, 3.06 ghz unit. And I believe it has 2 gigs of ram. Should I dig up any more info?

thanks

Thanks for the help Gerry! I opened the tuning dialog and it takes about 1% of the CPU to jog one axis. Then with the dialog open it takes about 18%-24% just to jog one axis. I'm so happy to know where the problem is, Thanks! Now I need to deal with it, but i could use some advice. I feel like i have a few reasonable options. Is there basic house keeping I can do on the computer to make the cpu more efficient. I could add a graphics card if it would help significantly. Or is a faster CPU the best solution. Right now i have to slow things to about 2000mm per min to run smooth, and with the dialog open I can run it at about 10,000 and it's still smoother. For what's it's worth I'd be interested in fielding anyones opinion. This has been driving me crazy for a week. Thanks.

thanks for your responses. The steppers ran so well at low speed that I skipped the trim pot adjustment. I'll go back and do that along with adjusting the pulse width and the ports and pins settings. It sounds like these are things I should check anyway.

The fact that Mach runs differently when that window is open, makes me think that it's my computer system. I'll spend some time going through the list of "house keeping" steps to see if anything helps. Thanks so much for your help!

First Id like to thank everyone who fields these questions. I've found amazing info in the various forums on line. Enough info in fact to build a nice little 18" x 30" x 6" router. It's turned out great, I've even cut a couple of parts, but i have a nagging problem. I'm trying to get my motors to run smoothly and have been experimenting with a lot of different speeds and acceleration to try to acheive this. Whats puzzling is that if have the motor tuning dialog open I can get them to move smooth as butter at top speed (25,000 mhz). But then when I close that window and am jogging the motors they run really poorly. I'm running a g540, mach 3, 48v power, 12 amps, and 381 oz in motors. If anybody would like the specs on the motors I can supply those also. I bought them through keiling, for what it's worth. Thanks all for taking a minute to read this. I've spent hours searching for the solution, and am finally throwing in the towel and asking for help. Thanks again!!!!
