General Mach Discussion / Re: Lots of noise in system.

I finally got the problem sorted out!  
It turned out that it was the ACPI issue.  I just followed the instructions according to the XP optimization guide and now the machine works flawlessly at 67.5 inches per min.
As a note I am still using windows Server 2003.  It is a simpler operating system that has less flashy things compared to XP.

Thanks for the ideas guys.

First I will try out Kerry Harrisons program and if that does not work I will reinstall XP and go through the optimization page.
I have two questions though, when installing XP should I upgrade to service pack 2 or just leave it as service pack 1.  Also should I go out and install all the device drivers on the machine or just the ones that are required for running the cnc machine?

It is a fresh clean install.  I previously had it running on server 2003 but then decided to try it out on XP.  It turned out that server 2003 made it run much smoother, with XP I wasn't even able to get 15 inches per min smoothly compared to server 2003 it runs great at 72 inches per min.
I am kind of puzzled because this is a fresh install.  I have messed with a few things trying to turn off some services but nothing has effected it.

I finally got my machine up and running  but it only runs nice for a short amount of time.
When I start windows, server 2003 in this case, if I start mach 3 right away I can get my machine to move very smoothly and quickly for about 30 seconds.  Then some service or device seems to be starting and causing an epic amount of noise in the system.  When I run the driver test the graph shows complete crap, there is so much noise that the line is a wide black strip instead of a thin line with a few spikes.  If the driver test is started as soon as I start windows it will have a graph that looks exactly as it should free of noise but then gradually it gets worse until it is total crap.

Are there any clues as to what could be causing all this noise?

Well I finally got it running!  I decided to install Mach 3 on windows 2003 server edition and now the drives move very fast.  Though now they do not run very smooth.  I am currently running with a kernel speed of 45 khz which was smoother than 35khz and 25khz.
Surprisingly they run amazingly smooth is using the Axis calibration.  Any thoughts?

The computer is barely using any of it's processing power.  I will test to see if lowering the kernel speed lowers the time and int number.

Sorry, I have misrepresented a number there.  The 20uS number is when running at 100KHz.

It is an IBM thinkpad T43.  I have it on a separate port replicator so I may try plugging directly into the port on the computer.

It has a 1.83 ghz single core processor, 1gb of memory.  The OS is loaded with crap though so I will try doing a fresh install of XP and start over.  It will be a Saturday project.

I have tried it at 25KHz and all the other settings up to 100KHz.  The speed is identical at all settings.  I will try again later but right now I have some other work that needs to be accomplished.

Do you suppose that the problem could be related to running Mach 3 off of a laptop?

The time and int is between +19 and +20 when moving and when not jogging it is between +9 and +10.
I am not sure if I was looking at the correct number but the pulse frequency was everywhere between 650 and 800.
