New computer, new problems

Queue depth stayed 0
buffer load stayed 0

They will be at zero unless you have a program running.
Jogging with the keys uses a different control mechanism and won't show anything.

Even just G1 X20 F10 on the MDI line will soon show you.
There is MDI line entry on the diagnostics page, and you can run a loaded program from there with cycle start.
Even pausing with the spacebar will still indicate.

Exact stop is exactly that. Given a short vector move, it moves from the start of the vector to the end of the vector and stops. at exactly the location, then it moves to the the next and stops.
With set CV it attempts to move from vector to vector smoothly.
As you you can imagine, at higher speeds and really sharp change of direction, it either must change direction very quickly, and hence a jerk at the change of direction, or the corner gets rounded and it doesn't stop.
You can CV distance and feed rate on the Mach3 settings screen (alt6)
The CV distance is really an angular limit, at which point you get exact stop regardless.

Thanks again for the explanation of what CV and Exact stop are. I have the CV set to stop on angles > 120 degrees. The rest of the CV settings are unchecked. This is for sure not the problem as once it starts it will continue to do it on one axis in one direction. It sounds like static or something.
I changed out the card and found that it did not fix the problem either... It is for sure a windows 7 issue.
Since this computer has 2 hard drives in it I though heck, Ill just put xp on its own drive. This doesn't work so well... After running the xp install process it wouldn't boot. I had to run windows 7 repair to get it to boot back to windows 7. Whets wrong with windows 7 and mach3! Very aggravating...

I'm going to load up a large file and let it run to see if it does the same thing as when I jog.

Win7. Nothings wrong.
Youv'e just discovered
Realtime operation... You wish...
I reiterate. Read the whole blog
Time

attached is an audio file of what it is doing. Might help , I don't know.
Rename the zip file to .mp3

Ok... Well, I found that running a large file showed almost the same results except for buffer load was between 18 and 20. Queue depth was between 180 and 200. Tim in int. 4-16. While running the file it would run fine for a while and then start this bumping/stuttering. Then it runs fine for a while, then it starts doing it again..
From what I can tell it is not actually loosing steps.

In win7, something is running every 30 seconds or so hogging CPU time from Mach3.
Run,
Sched,
scheduled tasks.

It's in there somewhere. Keep disabling stuff.

For instance, look at
Task Scheduler Library
Microsoft
Windows
Application Experience
SETTINGS TAB
something might be ticked to restart very regularly if the task fails!!

Is your computer off the network? IE, Network ports turned off?

Screen saver turned off? Background screen change turned off? When your machine stutters, is there activity on the hard drive going on?

I'm on my second computer for my Mach system. If your other computer worked with out issues, perhaps going back to it would solve your frustration issues.

I'm running on what used to be my backup computer. I even upgraded to the lasted release of Mach when I made the transition. I've since had to go back to an old release of Mach. I kept having issues with running my 4th axis with the latest release. Got tired of debugging the system and removed it and went to the version that I knew how to debug.

The old computer was and the new computer is on my local network. I do have a few things to try tonight. I have the background changing via windows 7 background changer.. That will be turned off. I also have, and this really might be the problem, MSN Mesh installed. I did this so I could work on projects in the house and when I go to cut them the files would already be on the CNC's computer. Mesh might be polling and causing the problem. I'm also going to check the startup processes etc and see what I can get by without. One of these things are bound to fix this problem. (I hope!) I will know tonight.

After disabling numerous things in task manager, and everything else that has been tried up to this point, I finally got it... One thing that was different in this machine was the wireless card. Although I had a usb wireless adapter in my other machine this one is a PCIe x1 slot card (shortest slot about 1" long). I thought it might be nice to have it built into the machine...
Anyway, all the problems stopped when I disabled the card. Funny how things work in the CNC world of windows.

Thanks Neilw20 for all of your suggestions and time. It is much appreciated. And thanks to osphoto for jumping in with the network disabling suggestion
Thank you all! I'm so happy!
