I am very sorry Hood.
I was taking you as an Art Soft support person not realizing you are a user.
My apology and of course I emailed Mach support and expect them to solve the problem.
Again, so sorry, didn't mean it personal of course and thanks for your help.

Hood,

I have just finished reinstalling a clean copy of Windows 7 Professional 32 bit and Mach 3. The problem remains.

The optimization page you mentioned is outdated and intended for low performance hardware and not for a 2011 brand new multiple processors PC with top notch video card and full of memory. Nevertheless, stopping ALL services and processes except those required for minimum OS functionality didn't solve the problem either.

What am I supposed to do now? Read each and every post on the forum that describes an installation issue? Sorry, no way.

As a paying customer and with the installed base you have I am quite disappointed you guys don't have a methodical way of handling abnormalities and infrastructure issues. I am not even sure what type of Win 7 you support and couldn't find any document discussing that. I would expect some sort of debug utility that produce a log you can analyze or an application that runs on a machine and grade it for use with real time application such as Mach, highlighting problematic areas etc.

I am quite sure what I see is not unique and I am not the first client who runs Mach and get timing issues. Please collect all relevant information and return to me with relevant directions.

Thanks in advance for your support.
YK

It looks like the problem has nothing to do with the PC or O/S because Time in Int is very stable as long as there are no motors settings. Once these are set and M3 takes control over the hardware Time in Int starts bouncing.

Apart from the obvious, what are the settings that may affect frequency / timing?

Oops, please ignore my previous duplicated post (I just saw my initial post and your reply).

- For some reason Reset Device Select do not show device selection on subsequent M3 start. I did see that working before but now all I am getting is the legal notice. I even created a new test XML and worked only with that multiple times but it didn't bring up the device selection dialog box.

- Please see attached Device Test in action. It shows Pulsing Too Fast until it takes over and then System Excellent. While running Pulses Per Second keep on changing.

Strange, yesterday I post a reply from my iPhone but it's not here. Anyways, here are the answers:

- I don't have another XML. When moved from SS to PP I kept the same file and added Parallel settings as required.

- Time in Int bounce from 3 to 6 mS or from 4 to 7 mS. It changes quite rapidly, few times per second.

- Frequency runs between ~27.5K and ~28K but not as rabidly as Time in Int.

- SmoothStepper was unstable and kept on crashing M3. We invested more than a month trying to find the reason while replacing every component including SS, PC, cables, motors, drivers, plugin... nothing solved the problem. Once moved to Parallel port all problems gone and M3 became very stable.

- I don't have another XML. This is the one I am using since switching from SS to PP.
- Time in Int runs from 3 to 6 or 4 7 very rapidly (it changes few times each sec).
- Frequency runs from 27588 to 27988 (not as rapidly as Time in Int but changes constantly).
- SmoothStepper never worked well and kept on crashing M3. Once I moved to Parallel all worked well.

As mentioned above, this is the right file. I switched from SS to parallel and kept the XML.
So if the setup is OK, what else may cause the problem?
How can I trace the source that causes Time in Int to bounce? Do you know a debuger that can trace what the CPU is busy with during while handling your interupt?

Profile attached.
Please don't get confused with the file name, this is a parallel setup, not USB.

I went from 2000 to 0 in 200 steps. Still the same.
BTW, the [OK] button on that screen is not the Default so Enter exists but not saving changes.
