General Mach Discussion / NEED HELP - Stability issue
« on: January 21, 2011, 06:25:47 AM »
Just emailed the following to support so why not posting it here:
----------------
I am using a licensed Mach 3 on a fairly strong PC with Win 7 32 bit connected via parallel port to a G540 (in Jeff Birt's box) and a Sherline mill with Sure Step motors. Until a week ago the system worked fine, was very stable and the motors worked smoothly. With no visible reason the system became unstable, the motors started to stutter and resets are initiated with no request.
The problem started right after installing a brand new ShuttlePro and its plugin. Needless to mention, I disconnected and uninstalled it but the problem remains.
Within Mach I can regenerate the problem by simply clicking on the toolpath window and changing the angle of view. As I move the mouse in that window the motor stutter. Outside Mach I simply launch an application such as Internet Explorer and the motor stutter as well.
The computer works very well and smooth and is quite clean from other applications, not even an antivirus. Trying to identify the source of instability I've reinstalled Mach and killed each and every service and process other than those you can't stop while Windows is running. I even rolled back Windows to a version I know was before installing ShuttlePro and disconnected all USB's but nothing helps and the Time in interrupt constantly runs between 3 and 6 mS.
Unfortunately I couldn’t find information on what may cause instability and how to identify it as all popular applications are not real time and couldn’t care less of what is so important for Mach.
Truly appreciate your help.
